The Stumpjumper tire by Specialized was one of the first purpose built off road 26” tires in the early 80s. Today’s it’s among the most desirable tires for vintage mountain bikes and incredibly hard to find in any sort of usable condition. This pair is in amazing shape for their age, 40 years old. I have stored them mounted and under mild pressure and they had no issues getting them mounted and removed from the rims they are on. The tread is in fantastic shape and the sidewalls have no cracking or gaps. The yellow label on one tire is slightly more worn than the other but still intact and shows well.
Please look at the photos and ask questions before you bid. These are 40 year old tires and you should not expect to throw these onto your bike and rip around, they will mount fine but should be handled with care.
