I am new to owning a atv and have been reading different forums on this subject but yet to find the answer I’m looking for to go forth with a decision. First, I just purchased 2013 sportsman 500. I know can put 26 on with no problem. I ‘ve read that a 28 would fit but may rub with a 4 3 ratio on a new rim. I go to the local shop and they tell me that if I go to a 28 that they would need to put a clutch kit in it and a lift also to fit properly. Is the clutch kit just because of an oversize tire so that’ll ride the same as factory?? It’s a big decision and would like to be steered the right way and not just that they want more $$$$$ thanks for any help…..
