2000 Lexus LS 400 Owners Manual - Page 451

CHASSIS To equalize tire wear and help extend tire life, Lexus recommends that you rotate your tires approximately every 12000 km (7500 miles). 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. If the optional chrome-plated wheels are mounted, rotate them as pattern A. For the standard wheels, use pattern B. 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. 434
