hey all, me and my friends have kindof been unofficially researching trail, field, jumping, and powersliding tires for our sport quads. our group consists of: my 450r, a raptor, a yfz450, a z400, and my old 400ex. weve spend a fortune between all of us on tires, and we think weve found one ideal setup(of many setups there may be)....we are running bandit xcrs up front-- and the new holeshot xc's in the rear. this combo is awesome for powersliding, grips pretty well, and all the tires are 6 ply so there tough in the woods. i dont know if anyone else is testing out tires with there friends, but this setup is great...id like to hear what other trail riders are running for sport quad tires...
