If you want to be fast and dont need more clearance LTZ470 is telling you how to do that. and trust me he did his homework. but if you want more clearance and a good strong lite all around tire go with a taller mud lite. If you dont need more clearance than you have no more question to ask yourself just do what LTZ did. but if you need more clearance you have some question to ask your self. like how tall do i want my car to be. and how wide do i want my car to be. do i want a lift kit will i fit on most of the trails i ride if im wider. (I found that tight narrow atv trails are not cool for rzr. you can duck on a atv. but you cant on a rzr. if you stick to 50 inch trails you will trash the sides of the rzr.) also if you want to fly through the wide open trails you will need to be wider. and if you want to do deep mud you will need more clearance. this is what i did. I wanted to be wider but instead of using $125 wheel spacer i used that money for a nicer wheel with -43 offset. I picked motorsports tork wheel $400. I also wanted more clearance for the deep mud. but i wanted to keep my horse power so i went with 27 inch mud lite. this tire is lite and not so tall that it robs your horse power. but it is tall enough for a lift kit. Me and other people can tell you all kinds of things to do but what matters is what you want. So think about it for a day than post what your plan is and im sure you will get all the help you need. also if you want more clearane but dont want to be wider it can be done there is a post on it. maybe you want to go with long travle kit. like i say post what you want to do and you will get all the help you need.
