Hi, my name is Luis Navarro, Im from Costa RIca

I just bought and ARGO frontier and have some questions.

Can I change the tires? I have seen in youtube some ARGO with ATV tires, is it convenient? Can it float with other tires?
I have read that in warm conditions the belt has to be replaced frequently, is there any cooling system for it?

What parts I have to buy frequently? I read about the belt, tensioners, chains, what else?
