Reccomded tire pressure 265/75/16?

I tried a search, didn't find much. I just got my BFG A/T's put on, and am wondering what PSI you guys are running with 265/75/16 A/t tires? Thanks, they are at 35PSI right now which seems a bit high, but I could be wrong!!

I picked up 4 265/75R16 Cooper S/T's (load C = 6 ply) in October. The shop aired them up to 35psi when I left, which was way to much. I did the chalk test several times and it turns out I only 26psi to get a full tread pattern.

I run my 285/75 BFG M/T's at 35, I ran my 265/75 Avon M/Ts at 40. Try running a tank of fuel at 35, then another at 38, then maybe another at 32 and look at mileage. With the tires so new, you won't be able to tell much about tread wear, but mileage will be part of the equation.

This is how I've been told to set tire pressure, and it seems to work well... Look at where the tire meets the road from the side. Look at the tire as it curves coming up. You should have 3 knobs in full contact with thee road before the tier starts the curve up.

Now look at the tire from the front. The tire should be on the road flat across the width, it shouldn't bow up or bulge out in the middle.

Find a balance between those two states, and you should be all set!

I've been running mine at 65 psi. It's a little rough on the roads, but I get killer mileage!


.......No, not really.

35 psi for me. (BFG TA KO's)

I'm running Bridgestone Duelers and have them set @ 26 psi cold all around. As stated before, it's the only way to get a full contact pattern if that's what your rig calls for on the sticker with that size tire.

You can air up for better mileage but you lose traction capabilities and tread life.

Ya, I definately don't like that overinflated tire feel and ride. I think 35 is good, but I might go down a little to 32. Thanks for the replies!!

The tire shop aired mine to 40 psi and it rode like a tank. Plus, the only part of the tire touching the road was the center. I've now aired down to 32 psi and the ride has improved and the entire tread is contacting the ground. I haven't been able to tell much of a mpg difference between the two. BTW, mine are 265/75 Eldorado ZTR Sports (Cooper ATR's).

go by whats in the door on taco's and runners its 26psi, 35 is max load inflation, they will wear in the middle, the best way is to get a piece of chalk,-mark the tread and drive around 100 feet in a straight line, and see if its all gone, gone in the middle too much, gone on sides too little, totally gone- all good.

35 is not max load inflation on BFG's. 65 is if I am not mistaken.

26psi is for the tires that came on the truck from the factory. I know for a fact that 35 is NOT max inflation for my 285/75R16 BFG's...

It depends compleatly on what rim you have, and how heavy your rig is.

What you want to do is run as much pressure as you can to still get a flat contact patch on the tread. This will yeild you the best wear on the tire, and the best economy on the road.

There are formulas you can do to get a ball park area to start, but 265/75 is close enough to OEM I would start where you had your last tires, probally wont be much different.
