All 245/55R18 tires

245/55R18 is also written 245 55 R18, 245/55 R18, 245 55 18 or 2455518. 245 is the tread width in millimetres, 55 the aspect ratio (sidewall height as a percentage of the width), R stands for radial construction, and 18 the rim diameter in inches.

A 245/55R18 tire is about 726.7 mm (28.6 in) tall, with a sidewall of 134.8 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 245/55R18, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 245/55R18 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.
