name. SIENNA (U) Rotating tires To equalize the wear and help extend tire life, Toyota 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. See "If you have a flat tire" in Part 4 for tire change procedure. 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. Installing snow tires and chains WHEN TO CHAINS USE SNOW TIRES OR Snow tires or chains are recommended when driving on snow or ice. On wet or dry roads, conventional tires provide better traction than snow tires. SNOW TIRE SELECTION If you need snow tires, select the same size, construction and load capacity as the original tires on your Toyota. Do not use tires other than those mentioned above. Do not install studded tires without first checking local regulations for possible restrictions. SNOW TIRE INSTALLATION Snow tires should be installed on all wheels. Installing snow tires on the front wheels only can lead to an excessive difference in road grip capability between the front and rear tires which could cause loss of vehicle control. When storing removed tires, you should store them in a cool dry place. Mark the direction of rotation and be sure to install them in the same direction when replacing. Steel wheels with a compact spare tire and aluminum wheels CAUTION Do not include a compact spare tire when rotating the tires. It is designed for temporary use only.
