The model combines the compound and the casing in order to upgrade the performing safety. The tougher casing maintains the ideal tire shape and protects the tire from external damage. The casing, as a result, avoids punctures, cuts, and impact damage. The stronger compound also prevents tread damage, by resisting the tread's chipping, cracking and tearing. This combination ensures the tire's lengthened service life, as damage does not shorten its usability.
