All 305/50R20 tires

305/50R20 is also written 305 50 R20, 305/50 R20, 305 50 20 or 3055020. 305 is the tread width in millimetres, 50 the aspect ratio (sidewall height as a percentage of the width), R stands for radial construction, and 20 the rim diameter in inches.

A 305/50R20 tire is about 813.0 mm (32.0 in) tall, with a sidewall of 152.5 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 305/50R20, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 305/50R20 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.
