Tyre Size Calculator

Plus sizing your wheels and tyres is one way to improve both the performance and appearance of your car.

By using a larger diameter wheel with a lower profile tyre it's possible to keep the overall diameter of the tyre, ensuring that odometer and speedometer changes are negligible. By using a tyre with a lower profile, you gain improved steering response and lateral stability.

The visual appeal is obvious, most alloy wheels look better than the tyre, so the more wheel and the less tyre there is, the better it looks. Please contact Troy Autopoint for assistance.
