Temperature Changes and Tire Pressure

This is usually specified in the owner's manual but the experts at Ourisman Fairfax Toyota's service department can help you figure it out if you're unsure. Keeping your tire pressure where it should be will decrease the wear on your tires and improve the fuel efficiency of your vehicle over all so checking the pressure at least monthly (more with drastic temperature fluctuations) is a good idea.

Temperature Changes and Tire Pressure
A good rule of thumb to remember is that for every 10 degrees that the temperature rises or falls, your tire pressure will rise or fall by 1 psi. That's why the changing of the seasons makes it vital to check your tires' air pressure.

The Effects of Not Inflating Tires Properly
Not having your tires inflated to the recommended psi takes a toll over time. It impacts performance, fuel efficiency, and tread wear. Since tires are not cheap, this simple maintenance can save you a lot of money in the long run by keeping your tires in good shape longer. Also, it'll save you money at the pump.
