Tire Pressue Suggestion

I just purchased a 2012 Rock Warrior from a friend. It's got Duratracs in the stock size on the stock wheels, and have been run at 50psi.

I can't really do a chalk test where I live this time of year, so I was just wondering what you guys think of running these at 50psi. Any advice or suggestions is much appreciated. Thanks!

 

Hey Dave..
what is the max psi rating printed on the side of tire?

 

Mine is e-rated 80 psi max and I run at 45 psi. I tried at 50 and found them to be bit harsh.

 

I ran my duratracs at 45 also

 

Thanks for the replies, guys! Max pressure on these is 65psi.

 

I have stock looking Michelins. Inside the door says 31 psi front 33psi rear? I run them at 35-37 psi. I would like to go higher for better gas mileage but need traction in snow and ice. Great question. Peace. D

 

I have a different tire but same thought process. The PSI in the door is only for the OEM tires.

I am running BF Goodrich All Terrain T/A KO2's, which are a 10 ply tire. I called BD Goodrich and they recommend running them at 55psi. I have been running them at 50. Too cold here for a chalk test at the moment, only had them for a few weeks.

Maybe call Duratrac and see if they have any advice?

 

I run my Michelin‘s about the same in the front but lower pressure in the rear. That way I get the same amount of tire bulge front and rear. Typically I set my fronts at about 38 psi and the rear 28 to 30 PSI. When I first bought the truck they had it set at the PSI in the doorjamb. Very uneven tire wear. Bumping up the pressure as well as the rear sway bar helped me tremendously.

I bump up the pressure when I tow or carry a heavy load.

 

My friend bought them at our local Goodyear, and they recommended 50 psi. I haven't been to the local Goodyear in a LONG time, but based on past experiences, I can't help but wonder if that recommendation has any technical basis.

 

Decided to follow suit . Running my Ridge Grapplers @ 45 psi on 295/70/18 's. So far rides good. I also did a speed comparison to see how much I'm off with bigger tires. To my surprise I'm only off 2+mph.
