I would for sure get 8 inch wheels for the rear NOT 10 inch. Skat trak haulers of edge depending on if you want a straight blade or V blade. I run haulers and love them.
Any decent sand tires are good for the front and will be better than knobbies IMO. I've ran anywhere from the cheaper ones to the expensive ones, and I run skat trak fronts now. I think I run 21x7x10 fronts.
