What air pressure should go in your tires?

Maintaining proper inflation is probably the single most important part of tire maintenance. But what is the right pressure?

While there are a lot of variables, and sometimes it'll take some trial and error, there are some general rules that can help get you off to a good start. Here are some general guidelines, along with a few myths or fallacies to avoid:

1. The pressure printed on the tire is the MAXIMUM, not a recommendation. Some vehicles, often heavier trucks, will run maximum tire pressure when heavily loaded. But for most cars running the maximum is too much.

2. The right pressure depends on the tire size and the vehicle. There is no such thing as a specific recommended pressure for a certain brand and model of tire.

3.  The manufacturer's recommended pressure on the door jamb is a great place to start. It will list a recommended pressure or pressures, and also usually tell you the load index of the original tire. If the load index of your new tire is lower, you may need to add some additional pressure; if the load index of the new tire is higher, you can still run the recommended pressure. 

4.  Keep an eye on treadwear. If the center is wearing faster than the edges, drop the pressure. If the edges are wearing faster than the center, raise the pressure. 

5.  If you have plus-sized your wheels, it is often a good idea to add some extra air pressure to help protect them from potholes.

I drive a 2008 Toyota Avalon. My tires are goodyear 215 60 16 v assurance tread comfort touring.What should my air pressure be?
Monday, June 14, 2010 by Ben:
For the Avalon, that is the regular size, so use the pressure listed in the owners manual/door placard. It will probably say 29psi, you can go higher if you like. For the Celica, if it is a shorter size on a bigger wheel than stock, use some extra air pressure above what is standard.

I have a 2003 bmw 325i sedan standard suspension. On 10/01/2010 purchased from Tire Rack 4 Michelin Pilot PA3 snow tire size 205/55/16 94V. I'm wondering because of the 94V rating should the tire pressure be lower than 32psi in order to get better handling in rain and snow?
Wednesday, December 15, 2010 by Ben:
Stay with the recommended pressure for the vehicle. The extra load capacity of an XL rated tire like this only comes into play at higher pressures, above 36 psi in this case.

I have a toyota4runner 2000 goodyear
tires PS/T P265/70R16 what is the pressure that these tires should have?
Monday, June 27, 2011 by Ben:
This is a normal size for the 4Runner, so stick with the air pressure indicated on the vehicle placard, usually found in the doorjamb. It will often be stated in the owners manual as well.

I have an F150, 2WD, extended cab with a fiberglass cap. I was taught to inflate to 5psi below what is listed on the door jam , because the tires heat up apon driving to the recommended pressure. True or not ?
Tuesday, February 7, 2012 by ben@tirerack:
Good question. Not true however. It is a fact that tire pressures increase as the tire comes up to operating temperature. Recommended pressures already account for this increase.
