What is the best tire pressure to run empty with bfg 285's l.r.E and h2 wheels. I know with 285's on stockers they say to keep the pressure down to wear evenly, but I'd like to know if this is a problem with h2's. I'd like to run full air pressure but want even wear also.

Why would you want to subject yourself and your truck to the punishment of 80 psi when you don't need to. When empty, that is actually unsafe, because so very little tire on the ground, especially on the back.

You need to air to the load. Meaning, that you need to weigh your truck empty and obtain a load inflation table for your tire and air to what it says. The fronts will pretty much not change, unless you are putting a lot of weight on the reciever hitch. So, you could run 45 to 50 in them and be plenty. On the rear empty, 40 would be plenty with that big of tire on the wider rim.
On my Dmax that I just got rid of, I ran 45 to 50 in the fronts all the time and 35 to 40 on the rears when empty, and 65 when I pulled a trailer and never changed the fronts. Had great tire wear, and the truck rode as good as an HD 2500 could.
Don't run max if you don't have to. It doesn't do you any good in any way. Just buy a digital guage and keep it in the truck with you so you can check periodiclly. REMEMBER. NEVER check/change the air pressure on a hot tire. Always air tires COLD. Hot tire is defined by the industry as a tire that has run one mile down the road. Very important.

So 55lbs of air is to much for my tires michelin 265/75/16.What would be a good air pressure for these tires.Im trying differnt pressures.They are 2 weeks new.The tires are 53 lbs cold and fill up to 55 hot.I think i have to put more air in the back tires when towing a heavy load i guess.My loads dont much go over 6000lbs per say.Sometimes higher.

The max psi for my tires are 65 psi and wasn't sure if it was okay to do so or not for even tread wear. I didn't think 60-65 psi would be too much as long as there is even tread wear.

I ran mine at minus 5lbs the recomended and they rode like a tank.If im not mistaken the high rating is 65lbs.So far 55lbs hot seem to ride good and not wearing yet.They are still kinda new yet.I put on 3000 miles per month or so.

If are not hauling anything in the back, at all, then you could probably run 40 psi and be good. 50 to 55 should work in the front all the time. You will probably put a little more weight on your tires since you have a long wheel base truck. All of mine are regular cab long beds.

If you like 55, then run them there and if they wear good, and you are happy with it, then that should be fine. I guess what I am saying is that you don't have to suffer with tires that feel like rocks when you are not pulling anything.
When you put a 6000lb trailer behind it, then obviously, you need to air the back tires up. Weighing the truck and trailer by each axle is the best way to know where you are in terms of axle loads and air pressure needed.

You might want to double check that load range. I run 60psi in mine and they are wearing good. I have had to replace two tires but the two original one have over 25k and are looking good.

55psi seems to be an all around good number for tire pressure these days and then you will need to watch them an adjust it for wear.
I monitor my tires every week with my gauge.

I used to think that since I never hauled anything, I might as well lower the tire pressure for a better ride. That started when I put 4" lift on an 89 Toyota P/U with 33" BFG M/T, didnt want to wear out the center at 15K miles....so I ran 15 psi in front and 10 in back, just enough for the sidewall to have a nice curve.

Two trucks later, I had a 98 Z71 with a 4" lift, I ran 285's on 16x8's and used that same thinking, 35 front, 30 rear psi for about 15k miles. One day I had it alligned at a very trustworthy shop here in Marion. They noticed tiny sidewall crackes....from heat as a resault of too much flexing.I was ruining my tires from the sidewalls to enjoy a smoother ride. They inflated the 285's to 60 psi front and rear and suggested I keep them there, at the tires recomended psi.

I was amazed at how much rolling resistance I was constantly fighting. With the correct psi, it was a whole diffrent truck.

I run 65 psi in the Firestone's on my 01 now, it may ride rough but if I want to haul, I dont want to get out the air compressor and guage everytime. Besides, Iv got a work car I drive to work if i dont need the 8' bed.
