I Bought Toyo M608Z's and Vision rims for my 97'. When I upgraded the truck to a 17' (both SRW) I attempted to get Rickson wheels for the new truck (Ford changed lug patterns so my 97' rims would not fit the 17'). After nearly 5 months of waiting for Rickson to ship I bought a set of Vision Heavy Haulers for the 17' and had my M608Z's mounted. I run the 265/70R19.5's (Class G). After the first few 1000 miles to break in the tires it rides like a dream. I added airbags to the 17' to level out the headlights. Ready to camp I'm at ~12000lbs.
