Rotating tires CAUTION Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries. D Do not mix radial, bias belted, or bias −ply tires on your vehicle, as this may cause dangerous handling characteristics resulting in loss of control. D Do not use tires other than the manufacturer's recommended size, as this may cause dangerous handling characteristics resulting in loss of control. Toyota recommends all four tires, or at least both front or rear tires be replaced at a time as a set. See "If you have a flat tire" on page 247 for tire change procedure. When a tire is replaced, the wheel should always be balanced. An unbalanced wheel may affect vehicle handling and tire life. Wheels can get out of balance with regular use and should therefore be balanced occasionally. When replacing a tubeless tire, the air valve should also be replaced with a new one. 82p104a To equalize tire 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. The wheel assemblies must be rotated as illustrated above. 295
