08 SIENNA_U (L/O 0801) Rotating tires 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. CAUTION Do not include a compact spare tire when rotating the tires. It is designed for temporary use only. To equalize the wear and help extend tire life, Toyota recommends that you rotate your tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the "Scheduled Maintenance Guide" or "Owner's Manual Supplement".) However, the most appropriate timing for tire rotation may vary according to your driving habits and road surface conditions. See "If you have a flat tire" on page 471 in Section 4 for tire change procedure. 528 Run −flat tires Some vehicles are equipped with run −flat (RFT) tires. The run −flat tire allows you to continue driving for up to 160 km (100 miles) at a speed below 90 km/h (55 mph) even if any tire goes flat. However, in some conditions (such as high temperatures), you could not continue driving for up to 160 km (100 miles). A spare tire is not provided on vehicles with run −flat tires. 2008 SIENNA from Aug. '08 Prod. (OM45455U)
