Tire size

285/60R18 tire size: dimensions explained

Common light-truck and full-size SUV size in passenger (P/Euro-metric) and LT versions. Below are the dimensions calculated from the size marking itself. Your vehicle's correct size, load index and speed rating are on the placard in the driver's door jamb; check it before buying.

Section width285 mm11.22 in

Overall diameter799.2 mm31.46 in
Wheel diameter457.2 mm18 in
Circumference2510 mm98.8 in

Calculated values: diameter = wheel + 2 × (width × aspect ratio). Real tires vary slightly by brand and model.

Reading the marking

285 is the section width in millimetres, 60 is the sidewall height as a percentage of that width, R means radial construction, and 18 is the wheel diameter in inches. A passenger (P or Euro-metric) tire and an LT tire in the same size are not interchangeable without checking load requirements.
