All 255/70R17 tires

255/70R17 is also written 255 70 R17, 255/70 R17, 255 70 17 or 2557017. 255 is the tread width in millimetres, 70 the aspect ratio (sidewall height as a percentage of the width), R stands for radial construction, and 17 the rim diameter in inches.

A 255/70R17 tire is about 788.8 mm (31.1 in) tall, with a sidewall of 178.5 mm.

An equivalent size is a tire whose overall diameter stays within 3% of 255/70R17, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 255/70R17 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.
