General Information

All models are equipped with metric sized steel belted radial tires designed to operate satisfactorily with loads up to full-rated load capacity, when inflated to the recommended inflation pressures.

Correct tire pressure, wheel alignment, and driving technique significantly influence tire life. Excessively heavy cornering, accelerating and braking will increase tire wear and significantly decrease tire tread life.
