Operating a vehicle with just one tire under-inflated can
reduce the life of the tire and increase fuel consumption. With the high cost
of fuel alone, proper tire inflation is an important consideration. In cold
weather, temperatures decrease the air pressure in tires, which adds to rolling
resistance, especially in snow. It is most important to check tire pressure
regularly (at least monthly), especially after a sharp drop in temperature.
Tire pressure can drop about one PSI for every ten degree (10oC) drop in
temperature. If you find your tire pressure has dropped, inflate it to the
correct pressure as soon as possible. The tire pressure that is indicated on
the tire itself is the maximum pressure for the tire itself and may not be
applicable to your vehicle. Check your vehicle?s owner?s manual for the
manufacturer?s recommended pressure.
Rotating your tires can help decrease premature tread wear
as well as improve fuel economy. Most vehicle tires should be rotated about
twice a year. Your vehicle owner?s manual will supply you with the recommended
rotation pattern and frequency for your particular vehicle.
Periodically inspect your tires for any cuts or
abnormalities, such as bubbles or excessive wear. Your vehicle's tires should
be kept with at least 1/16th of an inch tread of tire. Bald or unevenly worn
tires will reduce or eliminate any control you would have over your vehicle in
an emergency situation.
