@Tourershine what size Tyres were they? Did you like the look?
The tyres on the front 8.5's were 235/35/20 and I think the rears on the 10" were the same, but with a pretty extreme stretch.
Obviously these sizes are more for the looks on the aired out 6.1 and would be totally impractical and frankly uncomfortable on anything that's a daily driver or camper. If they were on mine, i'd be looking at a 235/45/20 all round, a tyre i've already run on 20x10s and it looks great to me, but still not ideal. My guess is these wheels would need some careful research for a load rated, yet good looking tyre that actually fits under your arch.
