A few years back, I put on a set of PR2s right before MotoGP in Indy. Day 1 they park us in the grass on the infield. Leave that night and my friend pulls up at one of the first couple of lights after leaving the track. Friggin roofing nail in the rear tire. Rode back to the hotel on the nail, pulled the nail and mushroom plugged it with my Stop & Go Plugger and limped the bike on the flat rear 1 block to air it up at the gas station. That tire ended up with 10k on it with trips down I 75 to Deals Gap, top speed runs, hard cornering, and fully loaded with luggage. Never leaked, never had a problem for over 9000 miles. Edit: I have learned since that happened to keep a small portable air pump with me, electric or hand pump. Had it all happend out in BFE, I would have been screwed.
