What Tyres Do I Need

How do I know what tyres to put on my car?

Look at the sidewall of any one of your tyres and note the numbers and letters on it. This information will help you find the tyres that fit your car.

Should all 4 tyres be the same?

Can I mix tyre makes on my car? – Ideally you should not mix tyre makes and tread patterns on the same axle – it’s important for the front two to match and the rear two to match. That’s because driving with mismatched tyres can pose a risk; causing an imbalance in steering, braking and rolling resistance.

  1. Aim for brand, tread pattern and size to be the same, along with speed rating and load index, if possible.
  2. To find out whether your tyres match in this crucial information, consult the sidewall of each tyre to for width, aspect ratio (the height of the sidewall as a percentage of the width), the rim size and the speed rating.

Sometimes it’s unavoidable to fit tyres that have different tread depths, but it’s recommended to get as close a match as possible. This advice may differ depending on the car manufacturer, so always get advice from this source to hear the specific advice for your vehicle.

How do I match my tires?

How to Choose a Different-Sized Wheel and Tire Combination When it’s time to replace your car’s tires, the natural move is to stick with the same size. Many drivers choose a tire from a different brand for better all-weather grip, handling, or braking performance, based on a, But replacing both the wheels and tires can make sense for some drivers who want much better performance.

  1. A common situation in which you’d change sizes is when buying winter/snow tires.
  2. Retailers often recommend moving to a smaller wheel and using a tire with a taller sidewall, without increasing the overall tire diameter.
  3. This creates a longer footprint, also known as contact patch, where the tire connects to the ground.

A longer contact patch can help snow traction. (However, a wider tire hurts winter traction by plowing through snow or even floating on top, akin to hydroplaning through a slushy.) Or you may want to upsize to a larger wheel and a tire with a shorter sidewall.

  1. This can be done because it’s fashionable and to improve three-season handling—a short sidewall has less roll and such lower-profile tires are typically optimized for grip.
  2. Putting performance aside, you may just want to switch to a more common wheel and tire size for the sake of availability and cost if you plan to hold on to a car for at least a couple tire changes.

Before making such a change, there are several things to consider. Illustration: Chris Philpot

For a wheel to fit properly, it needs to have the right lug nut holes and offset—the distance from the recessed hub mounting surface to the center of the wheel. The replacement tire should have an overall diameter that closely matches the original rubber to ensure that the speedometer, odometer, and overall vehicle dynamics aren’t affected. The replacement tires should have the same load capacity or higher to ensure they are rated to carry the same weight. The load capacity index can be found on the tire sidewall. It’s a two- or three-digit number after the tire size. (Learn more about reading a tire sidewall in our,) Tires are commonly split between metric tires for car and crossover vehicles, and LT, or light truck, tires. (An LT tire is built for more demanding applications and costs more because of its tougher construction.) The key is to be sure the tire is engineered for your vehicle’s demands and load. For all-season tires, use a tire with the speed rating recommended by your vehicle owner’s manual or listed on the tire information placard found on the driver’s doorjamb. This letter denotes the maximum sustainable speed and is found directly after the load index. Standard all-season tires are usually rated S (up to 112 mph) or T (118 mph). Climbing up the scale are the letters H (130 mph), V (149 mph), W (168 mph), Y (186 mph), and ZR (149+ mph). Though few drivers would ever drive to these sustained speeds, higher speed-rated tires generally offer better handling and wet grip than lower-rated tires. Generally, you may go up to a higher speed rating than the original tires to improve performance or move to a lower speed rating for winter/snow tires, but consult your vehicle owner’s manual for specifics.

It may seem daunting to sort through these different factors in selecting alternative wheels and tires, but tire manufacturers, local car dealers and tire shops, and online tire retailers can help. Not being adequately informed before you switch to a different wheel and tire combination can lead to the speedometer being inaccurate, the vehicle not handling properly, and the brakes not working as designed.

  1. It’s important to seek professional advice for your specific needs and vehicle to ensure proper fit.
  2. The wheels, for example, can have a compatible bolt pattern, but the offset or smaller diameter might not provide proper clearance for the brakes.
  3. Changing one size up in tire width and one size down in aspect ratio (the ratio of the tire sidewall height to width) will maintain approximate tire size.

As an example, a P195/60R15 has an overall diameter of 24.2 inches and a load capacity of 87. Move up to a wider tire with a lower aspect ratio, P205/55R15, and the overall diameter is similar, at 23.9 inches, and the tire has the same load index of 87. : How to Choose a Different-Sized Wheel and Tire Combination

Should I replace 2 or 4 tyres?

Replacement Tyres: Why is two better than one? · Posted by: Universal Tyres · on 15th January 2016 Your tyres are a key element to maintaining balance and stability when driving, so they must be kept in full working order for optimum handling and control.This article will look into why replacing both tyres on the same axle is better than just one so you can stay safe on the road.

Replace tyres in pairs on the same axle If you have noticed that one of your tyres is worn, damaged or punctured, it’s important to have it replaced as quickly as possible. Ideally, all four tyres would be replaced at the same time, however this is not completely necessary if only one needs to be changed.

That said, if you do need to replace a tyre, it’s advisable that you change the two tyres on the same axle as a pair to avoid creating an imbalance, as this can cause unpredictable driving in emergency situations. Investing in two replacement tyres will improve the safety and control of the car, as well as saving you from having to pay for four new tyres.

The key elements which must remain the same for tyres on the same axle include: – Brand – Tread pattern – Size – Type Official guidelines and legal requirements

According to UK law, your vehicle must be fitted with the correct type and size of tyre for the particular vehicle you are driving and for the purpose required. Build quality typically changes from company to company, so both replacement tyres must be made by the same manufacturer to ensure even wear.

  • During the fitting process, it’s important that the replacement tyres are inflated to the manufacturer’s recommended pressure – you could also take this opportunity to check the tyre pressure of your existing tyres too.
  • For superior safety, it’s also a legal requirement to only use tyres of the same construction type on a single axle.

The most common types in the UK are radial and cross-ply, both of which must not be mixed on the same axle. Seasonal tyres Although it’s not a legal requirement, it’s strongly recommended that you do not mix winter tyres with all-season or summer tyres as the different tread and performance capabilities can affect vehicle control.

If you are at all unsure about what tyres you need or whether your existing tyres need to be replaced, you must contact a professional as soon as possible so you can drive safely. Here at Universal Tyres, we offer a thorough and efficient tyre fitting service for all types of vehicle, application and budget, including winter tyres, performance tyres and 4 x 4 tyres.

We also supply a huge selection of popular branded tyres from industry-leading manufacturers, installed by our fully trained tyre fitters for reliable use for many years to come. For us, road safety is at the forefront of our business, which is why our dedicated and highly experienced team are always on hand, whether you require tyre repairs or a brand new set of replacement,

Is it worth getting all season tyres?

All Season tyres are designed to provide good performance in both warm weather conditions and more reliable than summer tyres in moderate winter conditions (cold, rain, some ice/snow). If you live in a country with extreme winter conditions a winter tyre would be a better choice.

How long should tyres last?

How many miles should tyres last? – Your front tyres should last for around 20,000 miles before being changed and your rear tyres may last longer than this. For example, this means that they should be changed every four years if you average 5,000 miles per year. However, they should be swapped sooner than this if you notice any of the problems listed above.

Is it OK to replace just one tyre?

Changing tyres in pairs – Whether you’ve experienced a flat tyre or noticed a puncture, it’s important to replace your tyre as soon as possible. But should tyres be replaced in pairs? The answer is ideally, yes. Replacing just the one tyre without changing the tyre on the opposite side of the axle at the same time may cause an imbalance to the vehicle – potentially leading to wheel misalignment and excessive tyre wear,

Having different ages or types of tyres on the same axle can lead to an unequal level of rolling resistance and grip, and it may also affect your steering and braking, too. This could be potentially dangerous in the event that you need to perform an emergency stop. If your tyres on the same axle are a mix of old and new, your vehicle may fail to stop in a straight line when braking hard.

Being on a motorway in such a situation for example, could spell grave danger. To check that your replacement tyre will be the same tyre as the punctured tyre – or that your tyres on either axle are the same, you can check the markings on the tyre’s sidewall.

Is it OK to replace just two tires?

When replacing only two tires, we recommend mounting the new rubber on the rear axle. This is because having fresh tires on the rear helps provide more traction and reduces the risk of hydroplaning. This is true even when the front tires are worn.

Is it OK to have 2 different tires?

For optimal safety and performance, Continental recommends fitting the same tires to every wheel position on your car, so drivers should have the same brand, size, tread pattern, load index, and speed rating on the front and rear tires.

Can a tyre be last for 10 years?

How Long Does a Tire Last? – Carmakers, tiremakers and rubber manufacturers differ in their opinions about the lifespan of a tire. The National Highway Traffic Safety Administration (NHTSA) has no specific guidelines on tire aging and defers to the recommendations of carmakers and tire manufacturers.

  1. Many automakers, including Ford, Nissan and Mercedes-Benz, tell owners to replace tires six years after their production date, regardless of tread life.
  2. Tire manufacturers such as Continental and Michelin say a tire can last up to 10 years provided you get annual tire inspections after the fifth year.

The Rubber Manufacturers Association said there is no way to put a date on when a tire “expires” because such factors as heat, storage, underinflation and conditions of use can dramatically reduce the life of a tire. Here’s more on each of these factors: Heat: NHTSA research has found that tires age more quickly in warmer climates.

NHTSA also found that environmental conditions, such as exposure to sunlight and coastal climates, can hasten the aging process. People who live in coastal states and other areas with warm weather should keep this in mind when deciding whether they should retire a tire. Storage: This applies to spare tires and tires that are sitting in a garage or shop.

A tire that has not been mounted and is just sitting in a tire shop or your garage will age more slowly than one that has been put into service on a car. But it ages nonetheless. Spares: They usually don’t see the light of day, but they’re still degrading with time.

If the tire has been inflated and mounted on a wheel, it is considered to be “in service,” even if it’s never been used. And if a truck’s spare is mounted underneath the vehicle, it’s exposed to heat, dirt and weather — all reasons to plan on replacement. Conditions of use: This refers to how the tire is treated.

Is it properly inflated? Underinflation causes more tire wear. Has it hit the curb too many times? Has it ever been repaired for a puncture? Tires on a car that’s only driven on the weekends will age differently from those on a car that’s driven daily on the highway.

Can car tires last 10 years?

It may be tentative, but tires do have an expiration date. There is a general consensus that most tires should be inspected, if not replaced, at about six years and should be absolutely be swapped out after 10 years, regardless of how much tread they have left.

  1. How do you know how old your tires are? There’s a code on the sidewall that you can read about here,
  2. Wear is a far more straightforward consideration: Tiremakers and safety advocates say a tire is worn out when its tread depth reaches 2/32 of an inch.
  3. That’s all fine, but what most car owners want to know is how long to expect a set of new tires to last before they need to be replaced.

“I wish it were simple to say how long each tire might last, but tires are different,” said Dan Zielinski, a spokesman for the U.S. Tire Manufacturers Association (USTMA). “Some tire manufacturers offer a warranty as high as 80,000 miles or more, reflecting confidence in that particular product’s longevity based on its engineering, technology, and design.

Other tires may be built to provide 30,000 miles of service.” Or less; some high-performance tires on cars driven aggressively will be worn to the 2/32-inch point without ever seeing 15,000 miles, but those are extreme cases. The average American drives between 14,000 and 15,000 miles a year, according to data from the Federal Highway Administration.

Zielinski said that, if you’re kind to your tires—that is, you aren’t constantly peeling out at stoplights and you properly maintain them—most new tires on the market today will last about 60,000 miles. For what it’s worth, the USTMA did a review of several thousand recently scrapped tires and found that most were three to four years old.

There was no way of telling how many miles were on those tires, but it’s easy enough to multiply four years by 15,000 miles annually to confirm the rough approximation of tire durability. If you want to figure out how soon you’ll wear out the tires on your car, Zielinski said it would be a good idea to start by determining how many miles you drive each year.

Divide the number of miles on the odometer by how many years you’ve owned the car (starting, obviously, from when you first got the car and accounting for any mileage it had on it at that time). Then you can compare that with any advertised warranty on the make and model of the tires and figure out how many years of service to expect.

If you live where winter tires are advisable and swap those onto the car for some months of the year, your regular tires will get less use and will endure for a longer period of time, but remember the caveats about tire age. Zielinski also noted that if you hit the wear bars at 50,000 miles on a set of tires with a 60,000-mile warranty, for example, tiremakers that offer such coverage will typically prorate the price of a new set.

In this example, you could expect a discount on the new set equal to one-sixth their price, or about 17 percent. You might not get it, though, if you decide to change brands. What Tyres Do I Need Kypros/Getty Images In general, the best way to preserve the life of your tires, and keep yourself and your passengers safe, is to maintain them properly. Here are some tire basics and maintenance tips: Tread A tire is considered unsafe, and should be changed, once its tread is worn down to 2/32 of an inch, according to the National Highway Traffic Safety Administration (NHTSA).

  • Many tires have tread-wear indicators, which are little bars in the tread that show when the tire is worn down to replacement level.
  • These will start making noise to alert the driver that they need attention.
  • You can also use a penny: NHTSA recommends putting the penny in the tread with Abraham Lincoln’s head upside down and facing toward you.

If you can see the top of Abe’s head, it’s time for new tires. Pressure To ensure even wear, tiremakers and auto companies recommend that vehicle owners check their tire pressures monthly. The pressure should be at the vehicle manufacturer’s recommended level, which is usually found in the car or truck’s doorjamb or in the owner’s manual.

One quick and easy way to check tire pressure is with a handheld tire-pressure gauge, which you can find starting around $10 at an auto-parts store. Tire shops will often check the pressure for you. Some gas stations have digital readouts as part of their air pumps; these are not always accurate, though.

It’s best to check the pressures when the tires are cold, meaning that they have not been driven on for several hours. So you’re better off checking them at home after the car has been parked overnight. Balance and Alignment Tires need to be round, and the tire/wheel combination needs to be balanced.

Rotation Rotating your tires can help prolong their lives. For front-wheel-drive vehicles, the tires in the front will wear more quickly and can be swapped with the rear ones. The inverse is true for rear-wheel-drive cars and trucks. All-wheel-drive models, too, may need rotation.

How many km can tyres last?

What does this all mean? – Generally speaking, tyres nowadays last for about 40,000km. That’s a significant leap over the 32,000km they lasted for in the 1970s. However, it’s hard to estimate exactly how long your own tyres will last. One thing that’s certain is that making an effort to keep your tyres maintained and inflated to the right pressure will help them last longer.

Is it OK to have different tyres front and back?

In this section, you’ll learn the critical information about mixing tyres on your vehicle. Primarily, you should avoid mixing different tyre brands and different tread patterns. There are rare exceptions for approved mixed-tyre fittings, but in general, manufacturers do not recommend tyre mixing at all.

  1. For optimal safety and performance, we recommend fitting the same tyres to every wheel position on your car, so you should have the same brand, size, tread pattern, load index and speed rating on the front and rear tyres.
  2. As a bare minimum, tyres must conform to recommendations concerning size, load index and speed rating as provided by the vehicle manufacturer.

It’s a legal requirement in many countries. Driving a car with a set of tyres with mismatched size, construction, load index or speed rating can pose a danger to you and other road users. It’s always best to follow the vehicle manufacturer’s specifications or consult a qualified tyre specialist.

  • If there are no special considerations, our recommendation is to rotate the wheels axle-wise between the front and the back on a regular basis.
  • Regarding timing, an excellent opportunity is the seasonal switching between summer tyres and winter tyres,
  • Alternatively, tyre rotation at mileage intervals between 3,000 – 6,000 miles (4,800 – 9,600 km) is also effective.

If you notice signs of uneven tyre wear, however, consider rotating them even more frequently. And ask your tyre retailer to check for any wheel misalignment or other mechanical problem. They can make the necessary corrections. Full-size spare tyres of the same size and construction as the regular tyres should also feature in your tyre rotation.

  1. Before incorporating the spare, however, don’t forget to check and adjust its inflation pressure.
  2. Speaking of air pressure, you should also adjust the air pressure according to the vehicle manufacturer’s recommendation for the new wheel position, as the specific pressures for the front tyres and rear tyres may differ.

Rotated tyres can also affect the Tyre Pressure Monitoring System (TPMS), if your car is equipped with it. Consult the owner’s manual or a qualified service professional to make the proper adjustments and recalibrate the system. First and foremost, our guidance is to fit the same tyres on all wheel positions of your vehicle.

  • However, if mixing becomes unavoidable due to a lack of availability or budget constraints, then it’s possible to mix tyre brands and tread patterns – but only so long as drivers fit a pair of tyres with the same tread patterns and brands across the same axle.
  • That means installing a pair of identical tyres on the rear axle, or a pair of identical tyres to the front.

It may also be possible to mix tyres with a different load index and speed rating if the load index and speed symbols are higher than the minimum threshold recommended by the vehicle manufacturer (extra load vs. standard load). In these instances, fit the higher-rated tyres to the rear axle.

Is it OK to have different tires front and back?

Staggered Tire Sizes – Unless your vehicle is a staggered one that requires differently sized tires on the front and rear axles, do not mix tire sizes. Mount the same size on all four tires, even if they are not the same tire brand. If a vehicle’s tires are too small or too large, they will hinder its performance.

Is it OK to have mismatched tires?

A matched tire set is best Generally speaking, you shouldn’t use a mixed or mismatched set of tires on your vehicle, unless the tire and/or vehicle manufacturer specifies that this is acceptable. (Some vehicles have what is known as a ‘staggered fitment’ – different-sized tires on the front and rear axles.)

Is it OK to mix tyre brands?

If possible, using tyres from different brands for your car should be avoided. This is to ensure safety and help you achieve the best driving performance possible. Essentially, you have to ensure that all your tyres are from the same brand. The size, load index, speed rate and tread pattern—should all be the same.

Is it OK to have 4 different brand tires?

As a general rule, tires should not be mixed on any vehicle unless specified as acceptable by the tire or vehicle manufacturer. Drivers should avoid mixing tires with different tread patterns, internal constructions or sizes, and use identical tires on all of their vehicle’s wheel positions in order to maintain the best control and stability.

Additionally, drivers should never mix winter tires with all-season/summer tires, or mix run-flat tires with non-run-flat tires. This is one of the reasons that it is desirable to have all of a vehicle’s tires wear out at the same time. It’s confirmation that the vehicle design, driving conditions and maintenance practices worked in unison to equalize tire wear and performance.

It also lets drivers know they got their money’s worth out of the current tires and allows them to choose a set of replacements that will either maintain the Original Equipment (O.E.) tires’ capabilities, or help tune the vehicle’s qualities to even better suit their needs.

  • Unfortunately wearing out all tires at the same time isn’t always possible.
  • Sometimes vehicle design, the use of differently sized tires on front and rear axles, insufficient maintenance and/or driving conditions conspire to prevent it from happening.
  • If a vehicle’s tires don’t all wear out at the same time, drivers are typically forced to decide whether they should purchase a new set of tires (forfeiting the worth of the two tires not fully worn out) or just a pair of replacements.

While purchasing a new set of tires is best because it will maintain the handling balance engineered into the vehicle while restoring poor weather traction, it is also more expensive. And while purchasing a pair of replacement tires reduces immediate expense, it brings with it the options of choosing exact, equivalent or alternative tires.

  1. Of the three, the best choice is to select the exact tire currently on the vehicle.
  2. This assures that the tire’s physical dimensions, internal construction, tread design and tread compound are equal to the tires being replaced.
  3. The second option is to choose equivalent tires from the same tire performance category that share the same speed rating, handling and traction characteristics of the original tires.

While this isn’t as desirable as selecting the exact tire currently on the vehicle, it can become necessary when the original tires are no longer available. The third option, choosing alternative tires, should only be considered as a temporary solution in an emergency situation.

Using alternative tires from different tire performance categories, with alternate sizes or different speed ratings can unbalance the vehicle’s handling in poor weather or when pushed to the limit in an emergency. Because tires play such an important role in every vehicle’s comfort qualities and handling capabilities, it is always best to drive on tires that are identical in every detail, including tire brand, model, size and remaining tread depth.

Anything else involves some type of compromise.

Should I change all 5 tyres?

How often should I be replacing my car tyres? – The lifespan of a tyre will depend on a range of factors, including your driving habits, climate, road conditions, the tyre quality and how well you care for your tyres. Your tyres should be inspected by the CMI Toyota Tyre team at least once per year and rotated.

It is recommended that your tyres are replaced at least every five years at a minimum, or when the tread is getting close to being at the legal minimum depth. If your tyres have not been replaced 10 years after their date of manufacture, they should be replaced, no matter how often you have driven the vehicle or the amount of tread that is left.

This applies to spare tyres as well. It is best to replace all four tyres at the same time. Mismatched tyres can affect the overall balance and road grip of your vehicle. If you are unsure as to whether your tyres need to be replaced, the CMI Toyota Tyre team are more than happy to look over them next time you’re in for a service or call our team to make an appointment for a tyre inspection. What Tyres Do I Need

How do I know my wheel size?

Tyre Markings: How To Find Your Tyre Size The writing on your can be confusing. The sidewall of typical tyre is imprinted with myriad codes and numbers that are used to identify the size and physical features of that tyre as well as details relating to its manufacture. What Tyres Do I Need What Tyres Do I Need What Tyres Do I Need What Tyres Do I Need What Tyres Do I Need What Tyres Do I Need What Tyres Do I Need Your tyre size can be found on the sidewall of your current tyre and is a sequence of numbers and letters. The most common tyre size in the UK is 205/55R16 but there are many variations so it’s important to check your existing tyre or to check your vehicle handbook to ensure the right tyre size has been installed.

What number should your tyres be?

Most passenger cars have a recommended PSI between 31 and 35 when the tyres are cold. But with so many different types of vehicles and tyre options you should always refer to your vehicle handbook for the required tyre pressure.

How can I tell which tire is low?

Thumb Check – You can use your thumb to check the pressure of your tire. All you have to do is push your thumb down on the tire to feel the pressure. Underinflated tires will be soft. You will find your tires to be extremely stiff if they are overinflated. The tire pressure is proper if your tire is not too soft or too stiff as mentioned above.
