Up for auction is a rare piece indeed. Im not certain of the year of manufacture for this tire...but it looks early for certain.  Its so hard to find NOS motorcycle tires from this era in literally immaculate condition.  This tire does not appear to have ever been used on any kind of road.  The rubber feels as supple as a new tire and looks like it could actually be used to ride on!  If I had a vintage motorcycle I would not be afraid to run this tire...its that good!  After a light application of some armor all, the rubber shines and shows very very well.  Either as a collector piece or street use, this is a once in a lifetime kind of find.

4.00 x 19 size.  If you have any questions or need more dimensions just ask.  Best of luck and happy bidding!
