tire pressure

[benny]

I've got a set of 10 ply wrangler duratracs, the sidewall says no more then 80 psi, I just want to get the most out of the tires and was wondering if anyone knows what a good pressure to run them at to get the longest life out of them. I have a LBZ 2500hd, the last time I had it on the scale it weighed 7100 lbs and I usually carry about 1000-1500 lbs in the bed. They're at 65 psi now and you can see they're just barely starting to squat. Thanks.

I like to got 70 in front & 60 in the rear when empty. When towing I go 80 in the rear.
I say just play around with the air pressure. See how they wear at different psi.

Think I run 65 all the way around and my tires have worn great.

I too usually run more pressure up front. 65/60 is about what I would do unless towing. Higher pressure will get you better mileage but the centers will go wear faster.

I run 65/55, but my rear tires will move slightly on the bead if I get on it real hard at only 55 PSI in them. Depending on the size of your rim and tire combo, you may need to run more or less tire pressure. Fo max tire lif you want to inflate them to where they wear as evenly as possible across the tire. I'm more after a smooth ride so I run a little lower in my rears to help smooth it out some.
