I ride primarily on hard gravel and rock trails/roads. There is an occasional mud run, but it's not a primary focus. I know this is a utility atv, but I"d like it to corner the best it can. From what I understand I want to switch to radial tires with a directional tread to have the best bite. I'm looking at BH 3.0 and Vipr tires. Not sure if I want to stay with 12" wheels and 26" tires or go to 14" wheels with either 26" or 27" tires. Thoughts or feed back for me? My fear with going too big is sucking the power out, though I know I can go with up to a 1.7 shim and "purple" spring in the clutches to gain some snap back at the expense of top speed.
