The salvage yard by me has gotten a buyout of 22.5 alcoa wheels. All are from 18 wheelers (kenworth/peterbilt) and all are 8.25" width for $150 each. Do the commercial 22.5 kits (southwest / chromewheel) use 7.5 or 8.25 wide wheels?? I am thinking of using a set of 255/70/22.5 tires on my 93 F350 4wd. I am trying to do this on the cheap so please spare me the "just buy the kit new" posts. the commercial kits cost more than what I paid for my truck.
