I went with Maxxis Bighorn 2.0's 26-11-12 on all four corners. I went with 11 wide for better floatation when crossing tundra. Originally decided on these for a couple reasons, price, availability for shipping to Alaska, and experience with them when I did trail surveys for the State for 2 years (put thousands of miles on ATV's over that time cut some Mudlites to shreds on shale) These are 6 ply radials and have done very well so far, I did some very tough terrain this past week from gravel roads, rocky slopes with shales and granite boulders (dented the frame on one rock), wet sloppy mud, thick sticky clay, rocky and sandy/silty creek crossings, thick brush, and downed trees from and old burn in the area. Yea seems like a lot to go through in one area but if you have been to Alaska you know this country is rough on people, machines, and gear. All in all I had a blast and was very happy with the performance of the tires and the P500 overall.
Please let me know if have problem with front tires rubbing against the frame in full turn?
