Drive Axle Truck Tyre
Block or lug pattern radial for driven axles, where traction and torque transfer matter more than rolling resistance. The axle that decides whether a loaded vehicle gets off a wet site.
Features
- Open block or lug tread that clears mud and slush instead of packing with it.
- Deeper tread than a steer tyre, typically 16 mm to 20 mm on mixed service patterns.
- Compound chosen for tear resistance where the vehicle leaves surfaced roads regularly.
- Three-peak mountain snowflake marked versions available where national winter rules apply to driven axles.
- Dual fitment needs matched rolling circumference; mismatched pairs wind up the differential and overheat.
