which also begs the question and makes me laugh--I schlepped this folded tire around through a third or so of Mexico, through Central America to Costa Rica, with nary a problem with the tires on the bike, and in the meantime, the bottom of my pannier did this to this expensive spare tire......

the whole reason I decided to use this tire is because my original Supremes are getting tired, and if I do this 5 day trip, there will be times that I'm not near roads, and so a problem would mean a pain in the arse walk of the bike....
