Tire Features
The tightly packed center tread blocks and high tensile strength belt construction help provide even wear, long miles to removal and casing retreadability.

The curb bar helps protect the sidewall from scuffing damage.
3D corrugations on the sipes help to lock the tread blocks together to maintain stability for traction.
Stone protectors in the tread grooves help protect the casing from stone penetration and help resist stone retention.
