What is the best tire pressure to be running unloaded?

Tires are 265's bfg's AT's D range FYI.

Thanks for the help!

 

I run about 35F and 30R when I had 35 BFG M/T's on my 92 and 45F and 40R with 33 BFG M/T's on my 96 loaded or not and they were real flat. Id say about 55psi or so F/R should be fine. Too much psi will were out the center and to low will were the sides. Most people run them at max and thats usualy way to much and weres out the centers. Max is fine if you are towing or have like 235-245 or so. I ran 80 with 245/75 E range when towing but it was like having steel wheels. Just watch how they were.

 

I nearly max out my fronts, both my old 265s (~80 psi)and now my 295s (~65 psi) and run a real low 35-40 in the rears of by QC short bed. No scientific reasons, just the way mine wear. My fronts still wear very slightly on the sides and my rears wear flat across and flatten the fronts back out when I rotate.

 

Like JLand said It all just depends on how they wear on your truck. Some times the same size will were diff even with the same psi becous of how they are made. You will just have to see.

 

Make a chalk or paint mark across the face of your tires and take a short drive on dry pavement.
If the chalk is worn away in the middle you have too much pressure.
If it's worn at the edges there's not enough.
I run 65 in the front and 55 rear when empty.

 

Good tip infidel

 

Narrower wheels need a little less pressure for the same tire size. In other words, the 16x8 wheel with a 265 needs more pressure than the same 265 tire on a 16.7 wheel.

On my 16x8 OEM wheels, I run 55F, 45R with great results.
