On/Off Road Mixed Service Tyre
Reinforced radial for tippers, mixers and crane-carrier chassis that run part of the day on unsurfaced ground. Trades rolling resistance for cut and impact resistance.
Features
- Thick tread blocks with stone ejectors in the groove base to stop stones drilling into the belt.
- Reinforced casing and sidewall for kerb strike, rock contact and site debris.
- Cut-resistant compound accepting higher rolling resistance in exchange for casing survival.
- Available in all-position patterns where the fleet wants one line for every axle.
- Suited to vehicles spending roughly a third or more of their operating time off surfaced roads.
