I
really like the razrII tires...and I've tried the 22's and 23's. I don't think I'd ever go to a 21. I see no difference in handling with the 23's vs 22's..I think the 23's would rub the fenders now and then on stock arms...on +2's I don't recall hearing it at all. I like the extra ground clearance of the 23's...may not be an issue for you if it's all sand terrain you're in, but for the rough stuff...trails and jumps..I like the 23's...an definitely the Razr's. I've run OEM, 400EX, some knobby thing, a pair of wide and flat (track tires??), and one or two others...sorry I don't know what they were. But the Razr's seem to wear well, and they steer awesome!
