So I picked up a set of 14X6 steel wheel for a trailer, but the funky hubs would let me mount them, so I decided to list them. Nearly Every single person that messaged me asked for date and codes on the wheels. I did notice the wheels all have the same code M 9 30 where the valve stem. I only briefly looked at barrel to confirm the size. Is there a value for a match set of rims like these and if so, how much?
