You can just buy the ring for the stock wheels if you have somebody local that can weld aluminum

 

How about the 22in. 6 ply Razrs. Can anybody give an opinion on these tires.
I am also thinking about getting a set of 22in. for some extra clearance on Rocky trails.

 

22 inch xct's are very good, just dont get in front of anyone on gravel, they sling rocks the size of your hand and do it non stop.
I have 23x7x10 and 22x11x10 XCTs on my Mod. Sport 400 that my GF rides now. They are very durable, the only downfall of 6 ply tires is their added heavy weight.
I have always found holeshots to be very good, i would reccomend holeshot xc's and mx's over any others for similar prices including Razors(they wear too quickly)
