We used them all last year in BITD. Its a good tire, and it handles well. It seemed like we got less flats then most, except one race when we got three. Sidewall seemed a little thin to me in my honest opinion.
I run Kenda XC tires, 22 rear 23 fronts
They by no means are the aggresive tires like itp and maxxis but boy do they shure hold up and work great in the desert. I find myself hooking up better then my friends who have rzr II's and ITP XCT's
Only problem i really have is the sidewalls, it doest get out of ruts or berms as nice.
Id say go for the tires if they are cheap, if not maxxis is the way to go
