I have BFG's AT's 265/75/16 not sure what presure to run in them.

 

Look on the side of the tire...

I run mine between 30-35 on the road.

 

35-40 around town
40-45 on highway

 

or where ever you heart desires

 

Personally, I run around 35. If the gauge says 34 or less, I fill'em to 36.

 

Neil, do you worry any about the tire face bulging and wearing funny?

 

i run these same tires at 32-34psi and there wearing wonderfully. got about 15000 easy on them

 

in my old truck 38psi in front, 35 in rear

 

.

 

no Colin - only downside is a bit of bouncing on highway frost heaves
MPG went up by increasing tire PSI by 10 - that plus tonneau got me 2 MPG
engine break in might have something to do with it as I am comparing first couple of road trips with less than 10k miles
anyway still have never seen better than 19 and that was down hill to NJ from Niagara Falls....
