    Can anyone tell me what the recommended tire pressure for my tires are?

    99 Tacoma with 31x10.5 R15 BFG All-Terrain TA KO Tires.

    Local tire shop set them at 40PSI, the tacoma manual says something like 30PSI.

    What do y'all run your tires at?

    Those tires only have a max load printed on the tire side. Which it says 50 psi IIRC. I would recommend the chalk test.

    i used to run my 31x10.5 15s at 35 psi for general on road usage. had em on my 02 ZR2. at that pressure they wore evenly and had good grip, werent too squirrely. much lower psi and the sidewalls start flexing too much, at least for my preference.

    I had two sets of 31X10.50 AT KO's on my Jeep Cherokee 4X4, ran them at 32-34 PSI and got 50K miles out of each set. Never needed to air them down even in deep sand. Great tires...

    The Manual is referring to the stock tires.

    I run mine at 38 or so on the road. Air down to 30 when im out on a trail or hunting, Rarely have to go any lower than that with the locker.

    The caulk test is simple.

    Using a piece of caulk, find an empty parking lot or long straight section of road. Put a mark on the tire across the tread with the caulk, do it on all 4 tires.

    Driving slowly forwar for about 300 feet or so, get out and look at the caulk marks.

    Where are they marked and where are they missing?

    If it is still marked on the outside edges and missing in the middle, the pressure is too high.

    If marked in the middle and missing on the edges too low.

    If the mark is about tht e same across, that is a good pressure to use.

    Adjust and drive till you get the caulk wearing even and use that pressure.

    Sometimes the pressures are different front to back, it is a truck you know. :D

    I agree with the above for a good set up. Commonly tires are inflated to 35 psi (on the papers that came on my bfgs it stated 40psi max) go higher and you ride center tread. This can possibly give you better mpg due to lower friction. Air down below 35 to give more grip and full tread grip. I wouldn't ever overinflated what the bfg website recommends no matter what anyone tells you. Just watch your uneven wear down the road. No pun intended.

    Does anybody know why Toyota recommends a lower pressure in the front? I just bought some BFG ATs from Discount Tire and didn't check the pressure til 2 tanks later. They set them at 26 front and 29 rear, which is what the door well says. It looked a little low to me so I set em at 32 front 31 rear. I plan on doing the chalk test tomorrow if it doesn't rain.
