Four wheeler tire experts please help?

I want a pair of mud tires( mudzillas or executioners). Would i have todo anything to my 2010 550xp? Or could I just snap the tires on and go? Kids were telling me I would have to get a custom clutch kit and other things. If I did have to how much would it be for a Polaris shop to put on everything except the tires because I can do that myself.? And what else would I need? Thanks!!!
