When it’s time to buy new tyres for you car, what are the most important things you should consider? Here are CarToq’s top five things to consider when picking out a new tyre.

car tyre buying guide

Tyres are one of the most important parts of the car, but are oft ignored until they begin to show signs of aging or act troublesome. Tyres aid in many aspects of the cars drivability from the braking, to acceleration, road grip and ride quality. It’s therefore important that you choose the right kind of tyre for your car.

Carmakers usually offer the best combination of tyre size and wheel size on the top-end variants of their cars, but do compromise on size and quality on the lower variants of their cars in the interest of keeping costs low. When you buy a car you could choose to either change the tyres straight away (and get a good price in exchange for your existing new tyres), or wait till the first set has worn out and then change to a tyre of your choice.

Life of a car tyre

The life of a car tyre varies with the size and kind of vehicle. Small hatchbacks tyres have an average life of about 40,000 km, but some even touch 50,000 km. SUV tyres can go about 60,000 km. Some expensive sedans with low-profile tyres only manage about 30,000 km from their tyres. The life of the tyre also depends on the compound used – softer tyres have better grip, but last less. Harder tyres have longer life, but may not be good at grip.

But all these figures can vary drastically depending on the driving conditions and maintenance of the vehicle. If you drive on bad roads, or drive fast and brake hard, you can reduce tyre life by nearly 50%. Or if your car has an alignment or suspension problem, this too will badly affect your tyres. And then there’s tyre pressure – always maintain the recommended pressure, checking it every fortnight.

Tread pattern

There are various kinds of tyres for different driving applications. All tyres have speed limits and load limits, which you will find on the sidewall markings. The tread pattern also varies. Unidirectional tyres only have the tread pattern in a single direction and you can’t swap these tyres to the opposite side of the vehicle during wheel rotation. All-terrain tyres have a deep and wide tread block pattern for SUVs to handle various tough road conditions. Mud-terrain tyres are specifically for off-road use, while HT or Highway terrain tyres are usually road-biased tyres. If you live in high-rainfall areas, it’s better to choose a tyre which has deep grooves in the tread for better water drainage and road grip on wet roads.

Tubeless or tube type

These days most cars come with tubeless tyres, which have a number of advantages over tube-type tyres. A tubeless tyre is less likely to lose air faster in a puncture and hence is more reliable. One can just fill air and drive for a bit, till the puncture can be fixed, as the nail / thorn acts as a temporary plug. They also generate less heat as there’s no friction inside between the tube and the tyre.

Size of the tyre

Ideally, when buying new tyres, stick to the car manufacturers recommended size. Usually this is the size provided on the top-most variant of the model of car that you have. But if you want a bigger size, don’t go over the limit, as a larger tyre will affect the odometer readings on your car as well as affect handling adversely. Always reduce the tyre profile size for each increase in tyre width size that you undertake.

For instance, the standard tyre size on a Mahindra Scorpio is 235/70 R16, where 235 is the width of the tyre in mm, 70 is the profile or sidewall height in percentage to the width of the tyre, a R16 denotes a 16-inch wheel rim diameter. If you want to increase the width of the tyres, the ideal upsize is 255/65 R16. Because even though the width has increased, the decrease in sidewall profile keeps the overall diameter intact.

The formula to calculate wheel diameter in inches is:

{[Width of the tyre x (profile number/10)] x 2} divided by 25.4 and add this to the wheel diameter in inches.

In the above example, the overall diameter of the Scorpio’s wheel with original factory-fitted tyres is 28.95 inches. When you upsize to the fatter 255 width tyres the overall diameter is 29.05 inches. As long as the difference is within 3% of each other, it is fine.

Thicker tyres are good for bad roads but will give poor handling as they have more flex and the car is not as sure-footed. Low-profile tyres are great for handling and precise control, but can be hard on the car’s suspension.

Tyre specifications

When buying new tyres, there are a few things you have to watch out for in terms of the specifications of the tyre.

Don’t put two different tyre sizes on the same axle (eg. a 235/70 R16 and 255/65 R16 on the left and right rear wheels respectively).

Ideally, all four tyres on the car should be of the same tread pattern and brand if possible for the best ride and handling.

If you have to mix tyres, ensure that the best two tyres are put on the front wheels of the car in most cars that are front wheel drive, as these tyres will have to pull the car, take care of steering duties and take the majority of the car’s weight on braking. On rear-wheel drive vehicles and MUVs ensure that the best two tyres are on the rear axle, as these bear most of the load and take care of driving duties (also in slippery conditions, they will tend to skid less).

When buying tyres, check the manufacturing date on them. Tyres that have been stocked with a dealer for over six months or more, will begin to harden and become brittle.

If all tyres are of equal age, ensure you rotate them every 5000 km. Undertake wheel balancing and alignment also every 5000 km to ensure the best life for your tyres.

Stick to the recommended tyre pressure and remove pebbles and materials stuck in the tread regularly to increase the life of the tyres.

  1. my swift dzire has Bridgestone 205/60R14 89H tyres, already covered 50700Km i think it will cover another 5000km, however the tyres at the time of delivery(JK tyres) done at 34000Km

  2. Gr8 article, just on time when I was seeking an expert advice for change of tyres of my mighty muscular. Need your advice on the same lines, does alloy wheels effect on the performance of the car, if yes, then what are the repercussions of the same, 2. What is the difference b/w All terrain and Highway terrain 3. Please guide on the use of these Nitrogen option in tubeless offered by most of the dealer’s.

  3. Also, since my pair are the original one’s accompanying the SUV and have done 82k till date, however I believe shall run for another 10k, still I would want to replace atleast two of them, would change of the front tyres will do?

  4. Hi Ankit, 82,000 km is definitely a lot of mileage on your tyres, especially for a Scorpio! I presume the original set are Bridgestone Dueler HTs? I would suggest you change all four tyres at the same time. HT or highway terrain has a tread pattern that’s narrower and hence has lower road noise. AT or all terrain tyres have a wider block pattern, which offer great grip in slush and snowy terrain, as well as on the road, but are slightly more noisy – they are however the best balance for on-road and off-road performance. And then there are MT or mud-terrain, which have widely spaced block pattern on the tread, mainly for offroad use. As for the use of Nitrogen, not necessary – normal air will do. Nitrogen is mainly a money spinner for dealers, and no real benefits can be felt on normal road-going cars.

  5. I drive a Honda City and could you recommend someone from Bangalore who can do a great work at economical price on the Header (Until Exhaust), except for Raj at RT Nagar (oflate he is bit expensive with his work)

  8. Hi there…….I have a Swift Dzire VDI with 165/80/14 tyres and looking for an upgrade to 175/70/14 however most tyre dealers have been recommending 185/70/14 which is offered in the ZDI variant or older variants of Swift Dzire. I have 5J alloys which has an ideal tyre size of 165-175 with a max size limit of 185. I would like to know which tyre size to look for and which brand of tyres are best suited for me. I am from Mumbai and not a very careful driver.

  9. To get most of the tire life, include the spare in your.tire rotations. Also don’t use tire cleaners frequently. The chemicals are not best for the tire rubber.
