What Air Pressure Should I Use in My Tires?

Many drivTire Placarders understand it's important to monitor the air pressure in their tires. Improperly inflated tires hurt fuel economy and cause irregular and/or rapid tire wear in addition to posing safety problems.  

It's recommend to check your tires' pressure at least once a month and before any long trip. Who really marks their calendar each month with a reminder to check tire pressure? I'll plead guilty that I don't. Instead, I check mine each time I wash my car.

You've got your air pressure gauge in hand and air compressor ready, but some will ask, "How much air pressure should I have in my tires?" Logic might dictate that one would simply check the sidewall of the tire, much like you do on a bicycle tire. However, this would be incorrect. The tire size used on your vehicle is also used on other vehicles and the recommended air pressure is different depending on the vehicle. For example, it may surprise many that a 2006 Acura MDX SUV uses the exact same tire size as a 2010 Chrysler 300 sedan.


Remember that the pressure listed on the sidewall is a maximum pressure only, not a recommended pressure. Instead, use the air pressure recommended in the vehicle's owner's manual or tire information placard label. The placard is typically found in the driver's side doorjamb, like the example in the photo above.

For more information on properly setting your tire pressure, read "Checking Tire Inflation Pressure."

Hi, I am trying to get the reccomended tire pressures for a few vehicles I have with custom wheels. I have a 1998 Lexus GS 400 with 20s 245/35/20, 1997 Cadillac DeVille with 18s 235/50/18 and a 2007 Lincoln Navigator with 26s 305/30/26

Your setups have sizes that we haven't tried so the following are my best guesses on what ranges I would start the air pressure at :

98 Lexus GS400 34-36psi
97 Caidillac DVille 32-34psi
07 Lincoln Navigator 35-36psi 42psi with passengers/luggage/cargo

recently purchased a 2005 Jeep with Hercules LT265/75R16 M/S tires. (OEM tires were 15", lable on door jamb does not provide info for a 16" off road tire. I am trying to locate the correct pressure required in the tires. Do you have that information?

We do not carry Hercules tires, nor have we tried this size on a Jeep so I do not have information on a tire pressure for this application.

What is the correct tire pressure for Michelin Pilot Super Sport XL on a Ferrari 550 Maranello. The tire sizes are 255/35ZR-19 and 305/30ZR-19 I purchased these from you to replace the stock 18s. Thanks
Thursday, March 14, 2013 by Gary

Barry,

These tires sizes will also use the same air pressures front and rear as your factory 18" sizes as the same overall diameter has been maintained for proper tire load capacity.

2004 Mercedes S-430 base but with 18" wheels and Driveguards 245/45/18. Recommended is 29/32, but because of the bigger wheels I believe the pressure should be higher. What do you recommend? Thanks
Wednesday, September 3, 2014 by Gary

Manny,

I'm showing that we would recommend 32/35 on that setup.

Hello,
I have a 2011 Mazda CX-7. I recently changed the OEM tires 215/70R17 with tires of alternate size 235/65R17.
For 215/70R17, Mazda recommends 32psi. Can I use the same pressure for the new tires, 235/65R17?

Thanks.
Tuesday, March 31, 2015 by Gary

Carlos,

Yes, you'll use the same air pressure with your 235/65R17 tires on the 2011 Mazda CX-7.

Jason,

We aren't familiar with that particular sizing setup on the Impala, but I would start with 36psi as a good pressure to maintain load capacity.
