215/40 R16 Tyre Dimensions

215/40 R16 is a low-profile small car tyre size and is rare on EVs. The first number is 215, and that's the width in millimetres. The second number is 40 and that refers to the aspect ratio. The sidewall height relative to the width is 40%, which results in a height of 86mm. R16 indicates that it is radial and that the tyre is fitted to a 16-inch rim. This tyre has an overall diameter of 578mm and, due to the shallow sidewall, this tyre has less cushioning on bumpy roads. We also offer 215/40 R16, including the XL versions, on Tyres.co.uk.
