Tire size question

I agree, B-E-A-U-T-I-F-U-L truck!

Another issue you haven't addressed is heavy steering. If you have Power Steering, it's somewhat of a moot point. However, wider tires and manual steering can be a real arm and shoulder workout! Chevy's generally had plenty of room in the wheel wells with their cars and trucks (Corvette being a notable exception) that clearance for a wider tire is not an issue. However, with that much larger contact patch comes considerably more stress on your steering system as a whole. Not just the linkage, but the steering gear-box as well. Some other brands/makes displayed some really serious problems with the wider and radial tires. Nash, Studebaker, possibly Ford, and some Chrysler products come to mind.
