Just curious what tire pressure you running. I have always run about 6- 8 psi but I read for sport trails or desers it should be like ...10-16 lbs
10-16 lbs--that seams high to me. I run 22" rear and 23" front 6 ply ITP XCT and Maxis ll.
Just depends on the sand and the kind of traction you're getting. If it's wet, dry, fine, course, etc.
Wet/course conditions i usually run more psi.
i never run over 4.5 in my tires for any riding. i think 5 is way to hard. but if you are in a rocky area it might be
better to have more air if your worried about bending a rim. but its gonna be a bouncy ride.
It all depends. Some times in the sand, I was adding air to allow the tires to spin a little more.
But even in the rzr, the highest I have been around 10psi.
