Tire, Rims, and Performance?

[jrm03]

I am going to be in the market for new tires and I had a few questions. My bike currently has what look like bear claws and they take a lil fun out of the handling of the quad. These tires are 22 x 11 x 9 on ITP aluminum rims. The manual says stock size is 20x10x9. Id like to go back to stock size with Holeshots or Razors. Will the stock size fit on my existing rims and would it be a good idea to go back to the 15 tooth front or stick with the 14T. I mostly ride trails and a lil mud. Thanks

with the front tooth rating either a 14 or 15 is your preference depending if you want more top end or more low end power
