Oil Field you need to check out the Interco Radial Reptiles. They are very aggressive while still giving a very comfortable ride. I have had them on my old Rhino, and now my Viking. I have 27" on "Man Child" and ran 51 miles an hour with three men in it. Discount Tire Direct ( website) is the best place I found to buy tires, and wheels on Atv's, and Trucks. Shipping is free, and no sales tax. If you buy both they come ready to mount. Good LuckIm running the 28 Mega Mayhem on mine and love them no clearance issues and mine is completely stock.
