I have a pair of really old M&H Racemaster dragster slicks perfect for a museum or display car. They are 11.00 x 15 x 28 and have tubes that hold air. They are too dry to use for anything other than display but if you're looking for originality and authenticity, these are it. They have the M&H Tire Co Watertown, Mass logo on them which easily puts them into the 60's. Contact Dan 484 432 425 eight for any questions or to come see them. Thanks for looking!
