I'll be buying a new quad this weekend (new to me atleast), it's a toss up between a 250r and an older 300ex. Anyways, I have read through a bunch of posts and see alot of different tires that truly mean nothing to me at this point other then some common names. I am going to be riding in AZ, mostly dirt and maybe some thick sand in some washes. I want a tire that won't get a flat easy, but also one that is affordable and easy to come by. Any suggestions?

Oh and on that same note; rims, what types and what thickness? I may hit some jumps and I weight about 190 (dont' want to bend any rims...lol). Also since I am fairly new to the sport, when I say "jumps" I mean little homemade doubles in a field getting me 5'-8' of air...nothing big.
