What is a Directional tread design?
Tires with directional tread patterns must be mounted so that the primary direction of rotation matches the directional arrows on the tire sidewall. If all four tires are the same size, directional tires can be rotated front to back.
Tires with tread patterns that are both asymmetric and directional require left and right specific tires. Sidewall markings will identify the side of the vehicle and the primary direction of rotation for the tire. If all four tires are the same size, they can be rotated front to back.
