235/30 R20 Tyre Dimensions

235/30 R20 is a tyre size that is an ultra-low profile tyre designed for larger diameter wheel cars. The numbers are easy to understand. 235 is the width in millimetres. 30 is the sidewall as a percentage of the width, giving a 70mm sidewall. The R means a radial tyre on a 20-inch wheel, and the overall diameter is 649mm. This tyre size was designed with a shallow sidewall to make room for a large diameter wheel rather than for extra cushioning. We stock 235/30 R20 at Tyres.co.uk.
