I have a 1983 K20 with a 700R4, 350, 10 bolt front, 14 bolt SF rear, open diffs. The truck will see 50% gravel road driving and 50% mud. I have a set of 35X15.50-16.5LT TSL/SX tires on the way that I got a smoking deal on. I am going to run a 6" spring lift (another good deal from a mechanic friend), and am trying to decide on wheels to finish out this phase of the build up. I am probably going to go with steel wheels, something along the lines of Rockcrawlers. The extra weight versus aluminum is a bit of a concern, but I'd rather have the ability to hammer out dents if necessary. My question is, do I want the 16.5x9.75" wheels, or go with the 16.5x12"? I kind of like the idea of the narrower rim, to help hold the bead on the 16.5" tire. On the other hand, the wider rim will widen out the tire, and may help with flotation. Thoughts/comments?
