Tread design
Specially designed for trailer/semi-trailer use ensuring optimum performance in terms of mileage, even wear, casing integrity and retreadability.
Perfectly circumferential grooves with densely siped walls to provide high resistance to irregular wear, with added protection at the base to prevent stone trapping.
Tough, continuous ribs, without added siping, resist high transverse stress.
Robust zig-zag groove ensure excellent roadholding even on wet surfaces.
Groove geometry design prevents stone trapping.
Increased tread width ensures significant improvement in mileage.
Tread compound
Formulation which reduces heat generation, preserving casing integrity and providing improved resistance to tears and lacerations.
Casing structure utilises new-generation steel reinforcement in the bead to improve integrity and retreadability.
