What do you recommend for air pressure in the tires? Mine are a load range D and don't recommend inflating any more then 50psi max cold. I am currently running 36psi.

I run mine at 50. I've always run my tires at the sidewall pressure.

I'll put a little more in em' tom. I want these to last as long as possible. I hate buying tires. I think next time I might look into the Super Swamper trXus AT. I have a buddy who has them and loves them on a 1/2 ton Z-71. Depends on how well these last.

I'm running the Toyo M/T's, E rated. I think they go up to 65 psi(don't quote me on that though). I run them empty at 35-40psi and loaded 50. Never needed to air them any higher.

So far at about 20k miles on the tires the tread is still very deep and wearing fantastic.

I'm running mine at sidewall rating - 50. Always have run all my tires that way. I get good wear and good performance.

Yeah I would agree to use the max allowable pressure, especially for bigger tires. Improves stability in turns, improves mileage because of less rolling resistance, makes it easier to steer, and I think it's easier on the sidewalls since they dont flex/bulge as much on the bottom.

Not sure when the TSB came out regarding the steering stabalizers, but is was recent, anyway, I noticed that it was truly **** about tire pressures. There have been quite a few discussions about DW and it's relationship to both tire pressure and the steering stabalizer. The TSB takes the tire pressure to the max rating of the sidewall on the stock tires. Maybe this is how all tires should be run regardless of vehicle? All the reasons mentioned by adamkn are very valid and just maybe tires are rated for their best overall performance by the manufacturer. I have always used larger than stock tires on all the trucks I have owned and never had vibrations, wobbles, or excessive front end parts wear.

50 in front, 35 in the rear. I use the truck as a daily driver & don't tow or haul much of anything except my fat behind. I've got 66k miles on them & still have good tread.

I'm the same as Gumby. I only go 50 in the rear when I'm pulling a load. All the weight in these trucks is in the front.
