The durable compound and the ribbed tread design work together with the stronger internal structure in order to boost the tread and casing damage resistance. The durable compound elements prevent damage to the tread area by avoiding the tread's chipping, cracking ad tearing. The self-cleaning tread design prevents stone retention as rocks cannot drill into the tread area. On the other hand, the nylon casing prevents external damage, such as the punctures, cuts and impact damage from shortening the service life.
