Verify Tire Pressures

So I took my new (still stock) Jeep Rubicon Unlimited into the dealer for a "free" oil change and to check my TPMS that was acting up.

My guage said all tires were at the prescribed 37 per the door panel.

They said all tires were 4 to 5 psi low. They reset the TPMS and filled the tires. All's well, right?

Except I figured my guage must be crap. I threw it away and bought an electronic one. I go read the tires now 8 days post visit to the dealer. 60 psi in each tire! This new guage has to be way off. I go borrow the neighbor's old style guage. 60 psi.

Now that would explain the extremely rough ride wouldn't it.

Called the service advisor and explained the situation. He said that when the weather's warmer they always fill them up a couple of psi over the prescribed. I said 23 is not a couple and is your tech smokin' crack? Ok I didn't ask if he was smokin' crack. But, what the heck?

Let the air out to a much more comfortable 37 and wow what a difference that ride makes.

I run about 32 psi in the rear and 36 in the front. some run 30 psi. but I found that I have a good contact patch, comfy ride, and good, even tire wear with those setting (but will differ by tire, size, and weight of the vehicle).

That's some good advise there 1/3 wave. Always a good idea to look over any work done on your rig.

Hard to believe even a dealership could screw the pooch that bad, but I guess not.

I run 30 in all four on my TJ.

Rencently have been given the following for a perfect tire pressure (which I have been too lazy to implement myself, but I will share simply for the post count ;-)

Sitting on a level ground, a regular business card should slip under the side edge of the tire at the bottom 1/4" - adjust pressure to make it so.

...then did they reset your TPMS to 60 PSI?

The TPMS light has not come on and the tires are at 37 PSI. So I'm guessing they did not "set" them at 60. But it's going back soon so they can exorcise my possessed rear wiper.

I run about 28psi on mine.
