Wheels and Tires: Description and Operation

WARNING: Do not mix different types of tires, such as radial, bias, or bias-belted, on the same vehicle except in emergencies (temporary spare usage). Vehicle handling can be seriously affected and can result in loss of control.

If the vehicle is equipped with unidirectional tires, mount the tires on the vehicle only in accordance with the manufacturer's instructions for direction of rotation printed on the side wall.
Original equipment unidirectional full-size spare tires can be operated with rotation counter to the directional arrow on the tire sidewall, but will perform best when rotating with the directional arrow on the sidewall.
Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures.
