CHASSIS ROTATING TIRES (Sedan) SV63007 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. Pattern A: Except vehicles with the P205/55 R16 tires sold in Canada. Pattern B: Vehicles with the P205/55R16 tires sold in Canada. When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, out-of balance wheels, or severe braking. 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.
