Your tyre size can be found on the sidewall of your current tyre and is a sequence of numbers and letters. The first three digits. This displays the width of the tyre in millimetres. A tyre marked will measure mm across the tread from sidewall to sidewall. The fourth and fifth digits of the tyre code that immediately follow the tyre width.

The aspect ratio or profile height of the tyre sidewall is expressed as a percentage of the tyre width. The next two digits represent the size of the wheel rim that the tyre can be fitted to.

It is also the diameter of the tyre from bead to bead. So a tyre marked 16 will fit on a inch wheel rim. The speed rating of a tyre is represented by a letter of the alphabet at the end of the tyre size code and indicates the maximum speed capability of the tyre.

Tyres receive a speed rating based on a series of tests which measure the tyres capability to handle a set speed for a prolonged period of time. If you are unsure what speed rating you need, be sure to check your vehicle handbook.

Choosing a lower speed rating than that recommended by your vehicle manufacturer could potentially invalidate your insurance. Cookies and your privacy Our website uses cookies to place bookings and help us provide a better service.

The width of cars tyres can affect many things including: Noise levels Fuel consumption Braking distance Grip Likelihood of aquaplaning As such, changing tyres seasonally can be incredibly helpful to people who live in areas where extreme weather is common.

The Pros and Cons of Narrow and Wide Tyres Here are the main pros and cons of certain tyre width vs rim width combinations. Wider Tyres: Pros Short braking distance Better grip when turning Handles small potholes more effectively Wider Tyres: Cons Noisy Road roughness is more noticeable Increased rolling resistance and fuel use Difficulty on rutted roads.

Narrow Tyres: Pros Less likely to aquaplane Quieter Less rolling resistance and lower fuel use Increased driving comfort Narrow Tyres: Cons Poor grip while turning Longer braking distance As you can see, changing your tyre width at least in the winter can have huge benefits for you in terms of your safety, comfort, and even fuel costs.

What to Consider When Getting Replacement Tyres Replacement tyres of different sizes can be perfectly safe as long as you use a tyre rim width calculator to check that they are compatible.

Both ride and handling are considerably improved with a lighter wheel. This reduction in mass or the wheel also leads to an improvement in fuel economy, especially in stop-start traffic. A reduction in the weight of the wheel also allows the forces of acceleration and braking to be transferred better. Critical as far as India is concerned, alloy wheel designs that allow a greater airflow to the brakes, can considerably reduce brake fade and increase the life of the brakes.

Cornering performance, especially turn-in and steering responses, also improve dramatically when wheels or rims are upsized or taller.

Next step, getting the right sized tyre. But before you do that make sure that you understand how it works. Many aftermarket shops will try and sell you the tyre and wheel that makes them the maximum profit.

If you get the size wrong, not only the ride and handling of your car suffer, but it could also damage your car. There is a method behind the madness of upsizing tyres and wheels. There is a reason that every manufacturer offers a standard size of tyre and wheel rim on a particular car. So if you change from the standard size, one or all of these qualities will change.

For example, if you go for a larger diameter wheel, you will have to put a lower profile tyre on it. If you have completely smooth tarmac, the car will handle if you are driving on rails.

The first thing to remember is that there is not much scope to deviate from the total diameter of the tyre that comes originally fitted in your car without making drastic changes.

To calculate the total diameter of the tyre, add the diameter of the wheel rim to the size of the sidewall.

Read the marking on the side of the tyre.
