For a moment I thought you were referring to me when I sliced my sidewall open on Sledgehammer. Fortunately 20-30 tire plugs allowed me to plug the slice well enough to hold enough air make it the rest of the way.We wheeled sans spare on the trails in JV for many years. That is until I told a guy that we did and had done that. About 15 minutes into the furthest trail from camp, he sliced a sidewall so I had to run back to camp to get his spare. That also meant I had to run the whole trail to get there and then come back around to the head of the trail. After that little fiasco and them managing to hole another of his tires trying to get it jacked up to take off the first one, I no longer entertain those conversations. Don't wanna run a spare? No problem but I am not your tire monkey.
After two such events on the trail with catastrophic sidewall damage I won't run without a spare either. Fortunately I was carrying a spare the last time it happened in Arizona on Hard Ass.
