275/65 R18 Explained

275/65 R18 is OEM on select models of Ford and Ram pickups and suits large 4x4s. The first number, 275, is the width of the tyre in mm. The 65 is the aspect ratio. The sidewall height is 65% of the width, so of 275mm, it is 179mm. R18 means a radial tyre which fits an 18-inch rim. The overall diameter is 815mm. The large sidewall helps pickups absorb bumps on uneven roads. We sell 275/65 R18 on Tyres.co.uk, including the XL variants.
