All 285/75R18 tires

285/75R18 is also written 285 75 R18, 285/75 R18, 285 75 18 or 2857518. 285 is the tread width in millimetres, 75 the aspect ratio (sidewall height as a percentage of the width), R stands for radial construction, and 18 the rim diameter in inches.

A 285/75R18 tire is about 884.7 mm (34.8 in) tall, with a sidewall of 213.8 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 285/75R18, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 285/75R18 is scarce or expensive, or when they want a different width or rim size. An equivalent size is not an automatic swap, and we do not guarantee that it fits your vehicle: check the rim width range, make sure the load index is at least the original, and allow for possible rubbing. Add your car above and rely on the “Fits on your vehicle” label shown on each product to confirm the fit.
