Use and Maintenance of Tire
Selection of tire
Never overload the vehicle
Vehicle overload will increase the tire heat-up and accelerate the wear of tire
tread; which may increase the tire bead stress, cause tire bead damage and early
fatigue of casing ply, and reduce the service life of tire.
Select proper tread patterns
Longitudinal pattern: low rolling resistance and good guiding performance;
Dual-purpose and transverse pattern: high tear resistance and good driving per-
formance;Select longitudinal pattern for guide wheels and trailer wheels; select dual-
purpose and transverse pattern for driving wheels
Model Dump truck, etc. Cargo truck and tractor, etc.
