Dave,

From everything I have read, and everybody I have talked to, I seriously doubt that it would have come from the factory with red wheels if it is a 1955 model. 

Could be something like a Super 88 that came from our dealership. We had a 1956 green wheeled Super 88 on the lot in 1957. The customer that bought it liked the 15.5-38 tires and red wheels that were on a newer one on the lot, so they worked that in on the deal. So this particular 1956 Super 88 left the dealer lot with factory red wheels, not the green ones it was built with. Of course, there is somewhere a red-wheeled Super that has green wheels on it from the dealer.

Chances are someone switched the wheels around or repainted them. Could be it even sat around at the Charles City lot, or came back in, until 1957. According to records, any tractors they had on hand as of Jan 1, 1957 would leave with red wheels. So any that were still there were pulled back in and the wheels were repainted. I have run across tractors that had spent a year at a branch warehouse, then came back to the factory, and then got shipped out from there. Could be a possibility there.

We might be able to find you serial number if your tractor has the original engine block in it. Near the right rear motor mount, running vertically on the flange that leads to the mount, there will be a number stamped into the casting. That will be your engine serial number. That number was recorded on the back of the build card. You could call the museum and see if they would be willing to look up your card that way.
