225/30 R20 Numbers Explained

225/30 R20 is short sidewall tyre sizing suitable for cars with 20-inch wheels. The figure is quite simple. 225 is the width of the tyre in mm. 30 is the ratio so 30% of 225mm is approximately 68mm. R20 is a radial tyre on a 20-inch rim which has an overall diameter of 643mm. The sidewall is 68mm which does not give much tyre between the wheel and road and gives a rougher ride on a rough surface. We stock 225/30 R20 at Tyres.co.uk including the XL versions.
