look at your door jamb, however that would be for the stock tires, the dynapros will have a max tire pressure on the side wall in small print... try to keep it around that for less rolling resistance and better handling, will be a slightly bumpier ride but not by much...

 

I'll just second what Dagkana stated. I run my stock Duelers at 50psi and they are wearing great. Handling is not noticably different than 35psi.

 

the pep boys technician told me 35psi would be fine. damn it! he is trying to kill me

 

The Hankook website has the following info for my tire:

2001295
LT315/75R16
(35X12.50R16)
10 127Q 8.5 8.0-10.0 S 65 3,860 34.8 12.3 9.4 19.5 597 OWL

"S 65 / 3860" was listed under Max Load/Air & weight

I have no idea what the S means and i'm guessing the 65 is the psi for something with a weight of 3860

 

devo he's a pepboy tech... nuff said I wouldnt trust them any further than I can throw them... 65psi doesnt make sense it prob the actual weight of the tire, 65lbs sounds about right for a 315...

 

It's 65PSI. I've attached a pic. Isn't that really high for my car?

what should i do? 50? less than 50?

 

35 psi is fine. I run my 35's at that pressure and tons of others do the same. When putting the 315's on stock rims the tire tread will not run even across the ground when at much more than 35psi or so. If you run them to high you will wear out the center of the tire and you will notice that the inner and outer edges about 1" or more on either side of the tire will not make contact with the ground. The stock rims are really to narrow for our tire width, they work but we should be running at least an 8" wide rim.

 

65 is max tire pressure. I also run 35 in mine 315/75/16's on stock rims. The main thing you want to see is the tire setting up fine with no sags in the sidewalls and all of the tire from side to side making contact with the pavement. I have a low place in my concrete driveway. I ran water in it and then backed through it for a bout 6-8 feet. got out and looked at the thread marks I was leaving on the concrete. turned around and did the same thing with the front. Nice flat tread pattern on all four.
