That sounds way too high. Try the chalk test.. Get a piece of sidwalk chalk and draw a nice thick line straight across the tread of your tire. Drive straight about 100 feet. Stop and check the line. You'll notice the center worn off more than the edges. Lower the air and repeat until it wears evenly. That will be your new psi.

 

I have run these tires for 6+ years and have always run 35psi. I wouldn't run 45psi either. That's a little high and the centers of these tires will show it soon if you run them that high.

 

We have the same tires as well. I run 30 psi.

I chalk tested them per everyone's suggestions. The chalk test showed I could run them as low as 24 psi. The chalk test was nearly the same from 24 to 32 psi.

At 32 psi cold, I notice the ride quality to diminish.

 

I used to run 32-35 PSI on mine except on trips I would raise it to 40 PSI for slightly less rolling resistance.

The chalk test is good for maximizing traction and tire tread wear but it does not measure load capacity or sidewall flex. If you use this test stay in the mid to high range.

Also keep in mind lowering your pressure may trigger your TPMS sensors if you have them, so you will need to reset the threshold.

 

Like others have stated do the chalk test. But 26-30psi depending on if you have a 2dr or 4dr.

 

Thanks guys. Mine is a 4 door. I'll definitely be letting some air out of these things. They were hitting between 44 and 46 PSI and it was in the mid-30's outside. I'll bet if I left 'em alone until summer, they'd exceed 50 PSI in the heat.

I think I'll drop 'em to 30 PSI cold and see how that feels.

Thanks again.

 

I just got a set on my four door and when they were balanced and mounted, they had it all the way up to like 38 and I felt every single bump in the road. I dropped him to 32 and it seems absolutely perfect. I got a couple hundred miles now on them and no sign of excessive wear either. When I off-road, I drop them down to 25 as long as I’m not on pavement.

 

Chalk test x 100

No two tires will read the same. Weight, 2 door/4 door. Load range, etc

A 35 I've seen people run 24 to 28. The chalk test is the best for optimal psi

Im driving on 35x16 load e Hankooks. Light weight 2 door and the chalk test shows 23 (full tread contact) I run 25/24 cold.

 

I run 315/75/16 MTZ's too. Typically I run the following pressures depending on the conditions...30# for better mileage and on dry roads, heavy snow conditions I'll go down to 20-26#, packed snow/ice 15-22#.
Off-road 10# now that I'm running Beadlocks 5-8#. This is an excellent tire that hooks up on everything, flexes great, bombproof sidewall and great road manners!

 

Thanks Sinister. Mine are actually 17's, but they seem like an awesome tire. I can't wait to get out on the dirt with them.
