Tire Pressure
What tire pressure do you run and how is your tire wear?
Does running less then the recommended tire pressure effect miles per tread-wear?
I've been driving 200 miles a one way quite a bit and the expansion joints are killing me

Contact the manufacturer of your tires and ask for a tire inflation pressure table. Then run by a place with a truck scale and find out the front and rear axle weights. Using those weights and the inflation table you can figure out the correct pressure to run in the tires.

Yeah best would be to post your tires, the size and what ply they are. There are a few variating factors, like if your truck is a gasser or a diesel, longbox/shortbox. Whether you haul or tow at all.

Beerstalker has it nailed. You might be able to get your tire chart at trucktires.com . The only caution is that you need to bump the pressure up when carrying a load. I only run 35 psi in my rear duals, but it goes up to 55 when I load my truck camper.

Thanks that is just what I was looking for, I'll check out the charts. Just randomly changing pressure seemed wrong.

Kind of to add to this thread:
How much pressure is normal for the tire pressure to go up during/after a long road trip in the summer?
This last trip I made I put 55psi (cold) in them and they showed 70psi whenever I stopped. The tires have worn very poorly due to lack of rotation I think (by previous owner) and I was just wondering if that poor tread wear is adding to the friction (heat/pressure) of the tire. Is a change of 15psi high or not too bad? This is more of a "just curious" question as new tires are around the corner.

I figured 15 was a little high but not surprising with my poor tread wear and somewhat poor MPG.
