I run 10's with rzr2s, 22'' tires, and they are great. The ITP's aren't the strongest, but they wont break your wallet either. I have several sets, and use them for racing XC, and they work fine. I just bought a set of the BAJA fronts, see how they go and hope they come out with something like that for the back.
