Know about the perfect size of the tyre for your vehicle

by Huck Nall Hucknall Lane Service Centre

A car’s tyres come in direct contact with the outer surface of the road. Tyre’s performance is subjective to most of us whereas some go for acceleration, control, some think of grip and many of us consider speed and performance but we hardly consider noises and sizes of the tyres.

Tyre sizes are specified based on the vehicle’s height and the choice of the tyre size is mostly focused on ensuring optimal grip and control for the vehicle. The other dominant feature for tyre size being taken into consideration is the fuel economy and performances of the vehicle. One can choose different types of Tyres Kirkby-in-Ashfield based on different tread patterns, rim sizes, and quality. But it is recommended to get professional advice for the perfect size of your vehicle tyre.

When an object rolls on any surface it experiences friction that resists the body’s motion, this is known as rolling resistance. Tyres experience this friction and thus, it is the power coming from the engine that is used to overcome the rolling resistance. It is the engine’s power that overcomes this friction and helps the vehicle to be under motion. If the vehicle tyres experience more rolling resistance then more power is needed to overcome this resistance and thus it results in more fuel consumption. Is, rolling resistances impacted by the tyre size? The answer is yes.

Tyre Size

When we have larger sized tyres, the surface area shall increase. This increased surface area shall

experience more rolling resistance. As rolling resistances increases, the more energy is needed for moving the vehicle. For maintaining good speed, more energy shall be required for larger sized tyres which shall increase fuel consumption.

Tyre Weight

It is certain that larger sized tyres generally are heavier and we all know that pulling off more weight requires more energy. If your car Tyres Sutton-in-Ashfield are lighter in weight then there shall be a decrease in the rolling resistance experienced thereby improving your car’s fuel economy.

Types of Wheels

But still, if you are fond of larger sized tyres, then go with the lighter version of wheels known as the alloy wheels. Generally, the car wheels are made up of steel and this makes them heavier. On the other hand, the alloy wheels are lighter in weight and this helps in enhancing the vehicle’s controlling abilities, and gripping mechanisms. Alloy wheels of larger sizes though shall have a marginal impact on fuel efficiency but these wheels shall help in enhancing the control of the vehicle.

Car tyre size guide

Car tyres and wheels come in different sizes. Before shopping for a perfect car tyre, you need to know your car’s tyre size. Each tyre comes with sidewall symbols written on it. It is available on the tyre’s wall or in the vehicle’s handbook. For example, the code or the sidewall symbols on your tyre might be like this:

245 / 45 R16 91V

· 245- This depicts the tyre width in mm

· 45- This is the ratio of tyre height and weight in %

· R – Type of tyre diagonal or radial

· 16- Rim diameter in inches

· 91 – Load Index

· V – Speed rating
