Tires In addition to your regular inspections and inflation pressure maintenance, it is recommended that you have annual inspections performed once the tires reach five years old. It is also recommended that all tires, including the spare, be removed from service after 10 years from the date of manufacture, regardless of their condition or state of wear. The last four digits of the TIN (tire identification number) are found on the sidewall of the tire and indicate the date of manufacture (See Tire Labeling on page 530 ). Tire Maintenance In addition to proper inflation, correct wheel alignment helps to decrease tire wear. If you find a tire is worn unevenly, have your dealer check the wheel alignment. Have your dealer check the tires if you feel a consistent vibration while driving. A tire should always be rebalanced if it is removed from the wheel. When you have new tires installed, make sure they are balanced. This increases riding comfort and tire life. For best results, have the installer perform a dynamic balance. Improper wheel weights can damage your vehicle's aluminum wheels. Use only Acura wheel weights f or balancing. Maintenance 485
