I found this website that offers obsolete accuride rims Obsolete Accuride 20 inch wheels but I am not sure of the offset for my rims. Does anyone know this answer? I currently have 6 bolt stud piloted 20 inch budd rims.

6.00" W, 5 13/32" Offset Base wheel
6.75" W, 5 29/32" Offset
7.50" W, 6 1/8" Offset.

Mine came with 4 22.5 rims and 2 of the widow maker 20" rims. I found a full set of 22.5 with tires that are like new for 900$.
You might also see if someone could spin the centers out of your widow makers and weld them into 22.5 rims. That might be cheaper than buying new wheels! | | | | | Joined: Sep 2015 Posts: 54 'Bolter | | 'Bolter Joined: Sep 2015 Posts: 54 | Hy danzimbric, the offset for the 20" X 6.50" wheel is listed in my parts book as 5.75", hope that helps. Thanks, I mounted a 20 x 8.75 the other day without and interference issues on the rear. I found three 20 x 8.75 welded rims with locking rings locally and a fourth on craigslist under an add for a used tire. Two of them were painted olive drab so they may be off a military truck. I have seen several pictures of the 2-1/4t trucks with GMC 6 bolt wheels. Now I'm only looking for two unicorns. I may have to bite the bullet and purchase a couple new ones from Wheels...Now. At least I found a source and the interesting thing is that don't list GMC or Chevrolet under the vehicles on their web site.
