Welcome to Rota Wheels UK - the home of Rota Wheels in Europe

Tyre Size Calculator

Enter your existing wheel and tyre specification in 'Existing Setup' then enter the specification of your potentially new wheels and tyres to see what a difference it will make!

This tool is great for working out if your new wheels will give you more or less clearance to your suspension and wheel arches. If you have any questions or need help using it please do get in touch and we'll be happy to help you with it.

Tyre diagram

The image to the left shows your 'Existing' wheel and tyre (grey + black) with the 'New Setup' (green + black) overlaid.

This is a graphical representation of how your chosen change in wheel and tyre will affect your stance, poke and clearance.

To see the wheel to tyre ratio changes, and the Existing vs New tyres in profile select 'Tyre Image'.

For the measurements, take a look in the 'Data Table' tab.
