Looking at a K5 with a 6.2L, TH350, and 4.10 gears. Currently it has 38.5x11R16.5 Boggers on it. It's the guy's offroad toy, but it'll be my daily driver. Not as much serious mud around here as those Boggers warrant, so I'm thinking about stepping down to some regular Swampers. What would be a good size tire to keep the diesel happy with 4.10's and the TH350? It'll be my main mode of transportation in the non winter (read: road salt) months.
