Tire pressure

[Gregturley]

Trying to figure out the best tire pressure to run in BFG 265/75R16. I have a 2001 quad cab short bed 4WD. My daily drive is about 30 miles round trip with about 60% highway. Trying to balance ride quality with tread wear. Truck has hard tonneau cover, rear bumper that weighs about 140-150, and about 150 lbs of stereo equipment, and Bilstein shocks. Otherwise pretty much stock as far as weight goes. Please let me know what you think.

Do it by weight...

By weight is the best way. 

 

 

I like this chart as it has most sizes in it.

I would have agree with both of the above.

I would agree as well since your tires are a common size.  It's a bit of trial and error with goofy size tires.  Found that 44 in the fronts and 36 in the backs on 305/55/20's max 50psi load range E's got good ride quality without uneven wear...rotating religiously of course.

Thanks for the responses. I was trying to be lazy and see if anyone had ballpark pressure for my tire size because it is so common and I haven't had time to scale the truck yet. Right now I'm running 50 front and rear. Might try 45 front 40 rear and see how it does. I've heard the BFG sidewall isn't as stiff as the Toyo and some other tires and that they needed a little more psi for better road feel.

55/40 would be my WAG for a CCSB 2nd gen, but that’s only a guess.

If I had tire capacity weight at pressure amounts I could use my truck weights to finish out the math.
