If you are going to put wheels and tires I would say look into ITP SS Alloy wheels they have a lifetime warranty against bending, denting, or breaking, and they look nice. I wish Motosport Alloy would put a warranty like that on there new wheels because I would sell my SS Alloys in a hurry to get a set of those.
Tires look at a mudlite, or a mudlite XTR or the mudbugs. Also Swamplites are nice as well.
