All 285/35R21 tires

285/35R21 is also written 285 35 R21, 285/35 R21, 285 35 21 or 2853521. 285 is the tread width in millimetres, 35 the aspect ratio (sidewall height as a percentage of the width), R stands for radial construction, and 21 the rim diameter in inches.

A 285/35R21 tire is about 732.9 mm (28.9 in) tall, with a sidewall of 99.8 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 285/35R21, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 285/35R21 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.
