It's a 15x5, 4.5" bolt circle with a 2.75" center hole and the center is welded in. It has the numbers 23 on one side of the velve stem hole and 00 on the other side.

It came off of an old homebuilt trailer my father gave to me and I'm wondering if it's something worth saving or not. I think I have a pair, haven't pulled the other one out to take a looksee. This one had an old, weather cracked, bias ply tire on it that's probably older than me, the other one still is wearing it's old tire.
