OurDailyChallenge - Two of a Kind A pair of 20" split rims for an antique car with 4.50-5.00" x 20" tires. I bought these years ago when I owned a 1928 Chrysler with artillery (wooden) wheels and you never knew when you would need a spare rim. The car has been gone for years but these are still around. If anyone is interested in them, I would be happy to sell them to someone who needs them. (I have a third one too, not pictured.)
