I'd swear these were actual rubber tires if I wasn't holding a pair. These cool cufflinks are a great gift idea for anyone who is really a car nut. Hardcoat black enamel is used as the coating on the tire so you can be sure that the enamel will never chip off. If it does, just send 'em back for a new set. I like the chrome wheels myself. Dimensions: 1" x 1/2"
