I do not care for the recaps the side wall says Michelin Goodyear etc because they are just a newer tire case and look like it. A friend of mine has a pair that dry rotted in a few months? not sure why, Are you looking for the early 50 early 60's type Pie-Crust style side wall?

If you are looking for the late 60's 800-850 cheeter slicks used in S/ Class (non pie-crust) they are still made by M&H under number mnh-mvd-006 for the 800-850-14 cant remember the 15" number.
