Can I fit smaller Tyres to my car?

It depends. Wheels and tires are not interchangeable words. Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size.

Do smaller wheels go faster?

Yes, smaller wheels accelerate faster, but it doesn’t matter. It all has to do with the rotational moment of inertia. The moment of inertia of an object is simply how easy it is to move the object. The heavier something is, the harder it is to move.

Are smaller tyres better?

While larger-diameter wheels and tires should improve handling and high-speed performance, lower-profile tires also tend to have a firmer ride and may be noisier than the smaller, standard rubber. Some potential performance benefits may be offset by the additional weight of the larger tires and wheels.

Can I go down a tire size?

It’s possible to change the size of your tires without actually changing the diameter. One example is if you want larger rims – you can buy tires that compensate for the larger rims by reducing the “height” of the outer tire.

Do smaller tires affect speedometer?
