SHIPPING & RETURNS

Assembly listings contain tires with rims for sale. The listed price is for both the tire and the rim. The actual bolt pattern of the rim may differ from the one in the photos, please check the Item Specifications for the actual rim type.

This specific tire model features a BIASED ply construction.

There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.

The Overall Diameter or O.D. advertised represents the tire's overall diameter in inches, once the tire has been properly inflated and mounted per the manufacturer's recommendation. This advertised number is provided to Priority Tire by the tire manufacturer.

Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
