1idrod you cant have your cake and eat it to. if you do enough mud and snow than go with a mud tire. if you do alot of hardpack and rock than buy bighorns. the mud tire wont last as long on hard pack. And a bighorn or all-terrain tire wont perform well in deep mud snow or sand. I ride all type's of trails and i picked a tire that would be good for all of them. do to the fact that i like deep mud i went with a mud tire. I also like as much HP as i can get so i went with a light mud tire. mudlights have never failed me in the pass and i had a kfx700 for three years and never wore the tires out. in fact when i traded it in the dealer said nice set of tires. Thay still had most of there tread. This is about 3500 miles of trail riding. I do have to say that the roof on rzr makes a little noise when im rolling slow do to the tires. And i will put weather striping under it. like i say you cant have your cake and eat it to. just pay attention to your wants and pull the triger.
