Incorrect tire psi i think

[mharring]

Picked up a nail in my nitto terra grapplers! There 325/65/20 they were easly able to repair the flat but the problem lies i think they set that tire to the door placured 65 psi the other one in the front is 45 psi. Lets just say that driving is dangerous!! Hopping and bump steer like crazy. Whats every ine else running in there f250/350. The rest were at 45 psi seemed to drive okay. I also dont do any towing so that not an issue!!

I had that tire and size in a 22 wheel version. Ran it at max psi i think at 60 on all four with no problems for 28k miles. Recently sold them.

Seems high to me with any tire unloaded.
Put the truck in the street headed straight.
Draw a line across the tread.
Drive straight for about block.
If the line is wore off in the middle, too much air.
If the line is wore off on the outside, not enough air.
I set mine to wear on the outside just a little since you will gain some pressure as you drive.

That's the best way to do it.

That sounds like a separated tire or damaged from being driven while flat. Jack up the offending wheel and spin it, look forwards at the tire and look for the tread moving left to right, then look across the tread from the side and look for lumps as it spins.
