    Fully loaded with or without dem hos? I figure that bed can fit at least ten groupies.

    The problem with being that low is that fat chicks can still get in.

    I run 29-30 on my E's. If I towed I would go to 40psi. I offroad at 12psi.

    Start with 35 and work up or down.

    I asked a serious question so that I could get the best number from others that had experience. Thank you to all those that answered.

    But out of 25 post 17 idiots decided to crack jokes and post garbage about something else not on the topic. I will take my chill pill now.

    BTW I tried the chalk test and it did not work. I will try 35 lbs and see what happens. There seems to be no real authoritive info other than what the Max load is for such a tire.

    The Chalk Test-
    Inflate all tires to 40 psi cold. It is better to deflate to your pressure, as inflating up can yield lower psi results.
    Chalk tires. I recommend a bottle of carpenter's chalk.
    Run on flat surface 50' forward and reverse.
    Adjust psi until even wear.
    Add 10%.
    Adjust front-to-front deflection, inflating lower of two.
    Adjust rear-front deflection, inflating lower of two.
    Test drive at speed for 30 min.
    Pressure should not rise more than 10%.

    The Formula-
    The OEM Goodyear Kevlar 265/70/16/112 @ the recommended 30 psi, has a load capacity of 1,953 lbs after ISO metric-LT metric correction.
    The BFG KO2 LT/265/75/16/E @ 37 psi has a load capacity of 1,986 lbs(+/-1 psi=38 lbs).
    Inflate all tires to 37 PSI cold.
    Adjust front-front deflection, inflating lower of two.
    Adjust rear-front deflection, inflating the lower and deflating the higher equal amounts.
    Test drive for 30 minutes at speed.
    Pressure should not rise more than 10%.

    Thanks for a serious comment. I tried the chalk test with standard blackboard chalk and it did not show any differences from 50-30-lbs, always scuffed off even for a short distance.
    As you stated "BFG KO2 LT/265/75/16/E @ 37 psi has a load capacity of 1,986 lbs" but the truck weighs about 4500lbs so about 1125 per tire.
    I found some more information to lead me to fill to 38-39lbs. I also live in a hilly area which will also wear more on the sides of the tires. So for now I took very careful tread depth reading and will monitor them over the next few months.
    I have noticed I have lost the soft squishy ride of the stock tires, that to be expected. I am actually saving them as a summer set, rims and all.

    I also stated the OE tire has an adjusted load capacity of 1,953 lbs at 30 psi.
    Actual load capacity is inflated by the manufacturer for various reasons. Toyota seems to go with a x3 payload formula.
    If you were to inflate the OE tire to 1,125 lbs load capacity, you'd be at around 17 psi(extrapolated because it falls off the chart).
    If you were to inflate the BFG tire to 1,125 lbs load capacity, you'd be at around 14 psi(extrapolated because it falls off the chart).

    I think you need to revisit grade school math, mate. There are only two of us idiots here that contributed "not on the topic." Well, three if you count the guy asking for info that won't actually help him. With seventeen of us it would be a heck of a party!

    What didn't "work" about the chalk test? LOL

    I'm running Duratracs in same size and did chalk test for a couple hundred miles. Ended up at 35 psi so far and that is what I ran them at on 07 also.

    I did the chalk test too and ended up with cold pressure of 33f 29r for my 265/75r16 C-load Duratracs. At operating temp this ends up around 35f 31r, which so far has been working well for me.

    It's got a cop motor, a 440-cubic-inch plant. It's got cop tires, cop suspension, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas.
    I went from about 33 to 43 and its a huge improvement. much less rolling resistance and acrually a better ride imo

    Mine run 39-41 (265/75/16 KO2s) and the feedback compared to the stock is more than I expected. I was actually thinking of going lower before I saw this. Has anyone seen a video tutorial of a chalk test? I've seen it explained before like above, but I just don't get it. Kind of like IKEA instructions. Sure it says how to do it, but that means nothing to me in the real life application.
    Those who know always say it's easy, have a cookie, but I need to see it to understand what I'm looking for I guess.

    BFGoodrich recommends 50 PSI in order to meet/exceed the load rating of the original stock tires as you are converting from a P tire to an LT Tire.
