I have Michelin LTX/ATē 265/70R16 on my 1976 & 2000. Little bit wider and little bit taller than stock. Both have 8 lug Aluminum rims from the GMT800 series with the factory center caps. The lug nuts will need to be swapped to dual thread 9/16-18 internal with external center cap retaining threads and the newer seat taper. I see sets of 24 & 32 available all the time on Fleabay.
Turned out looking like the red and brown trucks in this post without spending the kids inheritance.
