    My friend said that he would not air down my tires with my setup do to the chance of losing a /forums/images/graemlins/dunno.gifseal. If I can air down what would be the lowest possible without any trouble

    Yes you can air down. It is safer to air down your 8" rims then a 10" rim. There is more sidewall pressure keeping the tire on the 8" rim then a 10".

    Narrower rims are a poor mans beadlocks.

    That is what I thought, I guess he just didn't know any better. It kind of surprised me when he said that. Thanks for the quick replies /forums/images/graemlins/grin.gif

    As long as your rims arent 16.5" diameter (they have a different bead design and dont hold well at low pressure).....like Harley said the 8" rim actually holds a bead on a 12.5" wide tire very well /forums/images/graemlins/thumb.gif

    I concur with everyone else, AIR EM DOWN. I run stock ralleys and have run white spokes, both 15x8. I take em down to 20 most of the time, could go lower but it works well as is. /forums/images/graemlins/k5.gif

    I run 8" wheels on 37-1250's and no problems yet at 10psi or so. I have reverse wheels which are the real poor mans beadlock.
