I am running 8-lug modern steels off a 91 Chev Suburban. I modified my steering arms and tie-rod for clearance. Large truck tire shops would work on them but they were all different sizes to. 2-15" on front one 16" and one 17" on the rear? These old trucks lead interesting lives over the years. I purchased commercial T/A's for my steel wheels and the are tall and skinny like the originals with modern performance and ease of maintenance.
