If you're gonna drive the rig, modern tubeless tires are a much better option. Cheaper to buy, any shop can work on 'em, you can get radials. Makes a big difference. Plus the smaller 10 bolt pattern is pretty common so used wheels are available at any time, vs. the two ton Chevy large diameter 10 bolt pattern, which is not common and the wheel upgrade there is more expensive. But still worth it.
