Needed for my project. 3 split rims with 6 bolt tabs on each. They measure 4 1/4" wide by 22" diameter and take a 600X20 tire. Typically on mid 20's cars.
I think the first were five lug...then they still offered the high pressure (two wheel brakes) after the balloon tired four wheel braked cars were made available.
Probably the offer was more to rid old stock then to alleviate any fear of the dangerous new four wheel brakes.
