I rider alot of snow and mud not to much on hard stuff the hardest stuff i would ride on is the grass and a dirt rode

 

I run the ITP holshot atr tires on my sportsman, with 4000 miles and just under half tread. if you don't ride to aggressive those would be grate. The next tire I would pick is the ITP mudlite xtr. These are both 6 ply tires. ITP makes the best tires.
