CHASSIS ROTATING TIRES Before storing radial, snow or studded tires, mark the direction of rotation and be sure to install them in the same direction when using them again. Tires should be stored in a cool dry place. Initial adjustment of the tire pressure warning system is necessary after you have rotated your tires. See "Tire pressure warning system" on page 371. 63L020a To equalize tire wear and help extend tire life, Lexus recommends that you rotate your tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the "Owner 's Manual Supplement / Scheduled Maintenance".) However, the most appropriate timing for tire rotation may vary according to your driving habits and road surface conditions. The wheel assemblies must be rotated as illustrated above. When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire inflation pressure, improper wheel alignment, out−of−balance wheels, or severe braking. 481
