All 285/40R23 tires

285/40R23 is also written 285 40 R23, 285/40 R23, 285 40 23 or 2854023. 285 is the tread width in millimetres, 40 the aspect ratio (sidewall height as a percentage of the width), R stands for radial construction, and 23 the rim diameter in inches.

A 285/40R23 tire is about 812.2 mm (32.0 in) tall, with a sidewall of 114.0 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 285/40R23, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 285/40R23 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.
