The Stovebolt Site Forums The Shop Area Driveline will trailer wheels work on the truck?

There are no markings on the outside of the rim.
I think they are clearly marked in the inside with the size stamped in the rim. They came with labels and stickers on the rim but do not remember what all was on the labels.

My installer did not look twice at the rim other than to confirm the size matched the tires.
Think Installers will be more likely to question a 60 year old rim that is riveted, rusted, pitted in the bead seal area, likely could be bent, originally set up for tubes. Even an restored rim might generate more scrutiny.

Since the truck is 7/16" studs and the wheels are 1/2" holes wide burge lug nuts are the best solution to center things up.
