If a vehicle isn't going to be driven on the road, I think this is the perhaps the cheapest option for all-purpose high mobility tires: [Linked Image]

The pic is kinda silly, but that gives the best view of the tires I could find. The agricultural tires are mounted on 15 inch rims. TIres of that type run about $50 a piece(much less than DOT approved mud tires). Unfortunately, I don't have any means of comparison against dedicated mud tires such as Swampers or BFG's as I have never used them before. Might anyone be able to offer some testimony as to the effectiveness of mud tires vs. agricultural tires?

My '86 4Runner went to the bone-yard November 29, 2004 at 10am after roughly 430,000 miles on the original engine and transmission. :-( Looking for something else to wheel in...
