Re: what 's the correct air pressure when doing it on sand, on highway, and on offroad.?
The tire guys put 45 psi in my new tires and the mpg did increase, barely, but the ass ache wasn't worth it. Dropped to 36 and its perfect. Haven't done any trails that required 18psi, YET! But @ 36, the last trail I did do I should have dropped to 25, but no slippage, just a little rough and had to go a little slower to make sure I didn't blow one out.
