All 275/35R21 tires

275/35R21 is also written 275 35 R21, 275/35 R21, 275 35 21 or 2753521. 275 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 275/35R21 tire is about 725.9 mm (28.6 in) tall, with a sidewall of 96.3 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 275/35R21, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 275/35R21 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.
