If a Ford guy may comment, a 1947 GMC 252 would have been fitted with Motor Wheel brand wheels, 16” x 6”, having the 6 x 7.25” pattern. As pictured in posting #2. MW identifies this as their #83083, GMC #2219038, having 4.25” of offset, and using the Firestone RHP rim design. The center disc has a 5 3/8” center bore. The RHP rim can still be serviced if you can find a shop that knows how it’s done. If you just want to replace them, it seems to me that either a Budd 71320 (six hand holes) or the later Budd 79120 (three hand holes) would be your fix. These are 17.5” x 5.25”, same 6 x 7.25” pattern, and having an in/out coined mounting similar to the pictured Motor Wheels. Their center bores are 5 9/16”. They have 4.75” of positive offset. These have the 15° tubeless outer rims and use 8-17.5” tires. These wheels were commonly sourced on Ford, Dodge, and Studebakers after 1956 and optional through about 1966. Do a Google search of those Budd numbers and my Truckdog62563 user name to find a lot written about them on Ford sites. Stu
