    I don't have the money for the powertank I want right now, but everyone swears airing down dramatically increases traction, so I want to try it. The gas station where I can air up is about 10-15 miles down the paved road from the trail. I need to go 45 mph on it, so whats an acceptable amount of air to have in the tires. I was going to try 22psi front, 20 psi rear for my first try, but if that is too low what is enough for the journy back to the gas station? They are 33x12.5 goodyear mt/r on 15x10" rims. Thanks.

    I ran about 12 lbs in mine they were 35 x 12.5 BFG muds on a 15 x 8 I would have to drive about 5 miles to air up. The closest place to fill up at the coast got rid of thier air hose, so instead of driving all over town I'm making a OBA kit. Then I can charge people to use it and make my money back. Just drive slow and do slow sweeping corners nothing to harsh.

    When I use to run my 31x10.50r15 Goodyear MTRs down to 15 psi on a 9" wide rim. I drove on the freeway for 20 plus miles to the closest gas station numerous times. I was going 70 mph. You wont have a problem, you just have to get use to how it feels. Be careful not to drive too far though because the tires get hot quickly. I drive around on slicks on my Firebird with 11 psi in the all the time. I have driven 25 miles this way with no problems.

    What I did was buy a 10 gallon air tank at autozone. I think it was around 15 bucks. It doesn't hold enough air to comptetly fill your tires but it can get all four tires back uo to arond 28. And that is good enough to get you back to air. And then you fill the tank up again...Dan

    If it ain't broke.......Don't fix it....

    Same tires...just the 35" flavor. Have the same problem....i allways air down to 10-12 psi...and have to drive to Anthem....the nearest air from Table Mesa road...i run 55mph...doesn't hurt her....just get used to the squishy feeling while driving until you can afford an air tank.

    You will be fine. Just remember the tires are hot and put about 2-4 PSI more in them that you do cold. Does take getting use to the squisshy.
    You will like it when you hit wash board or gravel roads big time. takes alot of the jarring out and your dentist will be very pleased. I run a lot of gravel roads to get to the trails around here (Tellico, Beasley Knob) and I can run double the speed with less of a beating when aired down to 20.


    I don't need no damn shop manual, I got a pornographic memory.

    Ive run 10-12 (and possibly less) in 33" bfg all terrains for 20+ miles of freeway to get to an air fill up.. no problems whatsoever.. main concern is that its not so low that the sidewall is rubbing on the inside.. to get that low it has to be practically empty though..

    in fact I like driving with minimal tire pressure, it rides sooooo smooth..

    as for traction Ive found that you have to be at 15 or less (9-10 is good but dont go alone or without a way to re-fill a popped bead) to really do good.. this is in extremely soft terrain like sand..
