Candies, super traction on chrome threaded plastic hubs. I got a pair of bright yellow ones that are as soft today as they were when I put them on the car in 1967. I never knew how the colors got mixed, but all colors I've seen were soft. I don't think they are still being made, but occasionally someone sells NOS ones on ebay. Frank, I'd think your best bet today might be to try some of the urethanes, such as those made by Paul Gage.
