How To Read The D.O.T. Stamp
For Tire Manufacture Date
(In The Example Above):
51 = Manufactured in the 51st week
of the year
07 = manufactured in 2007
Maintain your vehicle's tire pressure at the amount recommended by the vehicle manufacturer. Pressure that's too low will result in poor fuel economy and clumsy cornering; too high and the vehicle could experience reduced traction or even a tire blowout.
Ensure even wear on all four tires by regularly rotating their positions on your vehicle. Several factors can affect tire wear, including differing weights on the front and rear axles, mechanical issues and how tightly you turn to the left versus the right.
The cause of the air loss will determine how the tire is repaired. A rapid leak indicates a punctured tire, while a slow leak suggests that the wheel bead or sidewall is damaged. In some cases, it may be better to replace the tire instead of repairing it.
Regularly aligning your vehicle's wheels will reduce tire wear and ensure that you don't pull to one side when driving. You can also adjust the wheel alignment to achieve handling characteristics for specific applications.
