    I've been searching but having trouble. I just ditched the stock Rugged Trails today and went with the Bf Goodrich AT in 265/75/16 load range E. What tire pressure are you guys running with this tire? The shop took them up to 36 psi...does that sound about right?

    Damn, I'll bet that thing rides rough! 36 sounds high, especially with such a light truck. It's probably what is recommended in the tire but keep in mind a load range E tire is made for heavy trucks and heavy cargo (or extra plys for off roading). Depending on what you consistantly tow/haul, I'd drop it down to around 30 or under.

    30 isn't near enough in a 10ply tire.Way overkill on this light truck.My F250 came stock with 265/75/16E with 45 in the front and 70 in the rear.Running them too low is gonna cause premature wear.

    That's only partially true. If you run 45 psi on a truck this light, it'll rattle your teeth out with every bump in the road. Your old F250 outweighs these Tacoma's by a very significant amount, especially if it was a diesel. My old man is running E's on his 2500 now with similar PSI as you. The Tacomas don't have enough weight to squat the tires to make them wear evenly at normal PSI and pumping them up that much will cause the centers to wear out faster. You are correct though, load range E is ridiculous on these trucks unless you're worried about something puncturing the sidewall.

    Edit: Do the chaulk test with your truck normally loaded to find the sweet spot for the tires. You draw a chaulk line across the tread of the tire (left to right) and drive for a few miles. You'll see where the caulk is wearing off and can adjust the tire pressure accordingly. (If the center is worn and the sides aren't, let some air out, etc).

    i run 35psi on my KM2s in 285-75-16 on street and they run great... off road i drop them down to 20psi...

    in 265s i would try 30psi and go from there...

    After reading some say they like these tires and others not I was a little hesitant on getting them but since that size BF Goodrich A/T only comes in the E rateing I went for it. So far the ride seems great to me. The reason I asked about the psi was because I haven't experianced the bone jarring ride that I've read about here with the 10 ply tires. Personally I like the ride to be rough in a truck...after experianceing the mushy ride from the Rugged Fails these seem to be alot more stable. I plan on doing the chalk test to see if I can take them up a few more psi's.
    On a side note I read here when going up from the D rateing to the E you lose the winter traction rateing (something about the rubber being harder) but that's not the case...

    Something I was warned about with high load range tires is the compound wearing out and getting 'hard' before the tire tread wears down. Apparently the tire will start losing grip on wet or snowy roads after 40-50,000 miles even though there could be plenty of tread left. The rubber compound becomes hard with age and doesn't wear down completely but the tire will still need to be replaced. I haven't experienced this personally but figured I'd pass it along if there is any truth to it.
