03 12.25 Rotating tires 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 167 in Section 4 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. Do not rotate the tires as the tire sizes are different such as with front to rear, left to right or using the spare tire. Performing such tire rotation may result in the tires interfering with the body or in uneven wear of the tires, so that steerability of the vehicle is impaired. Tires with turning direction indicator- The tire is a uni −directional type and cannot be used for tire rotation. Using the tire on the opposite side to the designated side will impair the tire performance. The spare tire- The tire is designed for temporary use only and cannot be used for tire rotation.
