The tread compound, tread design and the model's internal structure improve the durability. The tire compound is cut and chip resistant. The tread design extends down to the sidewalls which improves the tire's impact resistance, while the sidewall design also protects the rims from accidental curb damage. The internal structure features a two-ply polyester casing, a two-ply nylon cap reinforcement and twin high-strength steel belts that maintain the tire's optimal shape in extreme conditions, even when the tire is deflated. This ensures a safer drive in all situations.
