Knowing About Different Sizes Of Tyres

Tyres are crucial when it comes to driving comfort, fuel economy and overall vehicle performance. They are also one of the major drivers of shock-absorption and efficient braking mechanism. Therefore, it is vital to ensure that you pick out the best possible replacement for your tyres.

There are several tyres’ components that dictate their performance, and one of them is sizes. Size is crucial because it dictates vehicle stability and steering control. However, choosing a perfect size could be technical, given that there are a plethora of options available in the market. Here is an article to assist you in finding the right-sized tyres for your vehicle.

Different sizes and their effect on your vehicle

Stock size: When you buy a new vehicle, the car tyres Coventry that come fitted with it are known as stock tyres. The brands that produce these tyres work closely with the vehicle brand to optimise the weight, shape and size according to the vehicle’s specifications.

The technology and rubber used in these tyres optimise the driving control, vehicle stability and performance. If you do not want to dwell deep into the tyre technicalities, just go for the stock tyre’s dimensions.

These dimensions are painted on the sidewalls in an alphanumeric code that looks somewhat like 160/45R15. In this code, 160 is the tyre’s width, 45 is the per cent of height of width, R denotes that the tyre is Radial type, and 15 is the diameter in inches. You can use these details to pick out the perfect replica of your stock tyres.

Large tyres: One of the primary reasons people switch to larger tyres Lutterworth is the addition of aesthetic value. If you drive a heavy vehicle with significant engine power and a huge car-frame, you can switch to larger tyres to give a more beastly look to your car.

However, apart from the aesthetic effect, bigger tyres also ensure better vehicle stability and handling. Larger tyres also ensure better grip off the surface because of the larger contact patch surface area. This added grip surface provides good vehicle control when speeding on highways.

The added contact patch surface area means that a greater frictional force will act on the tyres, making the acceleration difficult. As a result, the engine will burn more fuel to overcome the extra force, which will adversely affect the fuel economy. Also, larger tyres are heavier, which makes it difficult to steer around sharp corners.

Small tyres: Smaller tyres are extremely efficient if you want to improve your vehicle’s fuel economy and performance. These tyres are lighter in weight and ensure smooth acceleration. They have a smaller contact patch surface area which means less frictional force acting on them; this means the engine would burn less fuel in the acceleration process, improving fuel economy.

However, these tyres prioritise performance over stability. For this reason, they start to skid or slide on slippery surfaces and provide lesser control when the vehicle is speeding on highways.


Different tyre sizes come with their pros and cons. What matters is what you want to achieve out of your vehicle in terms of performance and aesthetics. If you own a powerful vehicle, bigger tyres will ensure better stability and control when speeding; but they will hurt your pocket eventually. Similarly, smaller tyres are preferred because of performance optimisation and better fuel economy.

If you go to buy a new tyre, note down your requirements and your vehicle’s specifications.
