Good lesson [MENTION=364898]Insidious C.[/MENTION] , I save valve cores. But they are all in my tool box. That doesn't do a lot of good when a valve core fails when you are out and about. These are so small and light that I ought to be putting them in my patch kits with the bike. Then there is always Murphy's law of, if I take a valve core with me, a valve core will not fail and I will be hobbled by something else. In that vein of thinking, I need to cut up an old silk tie for an emergency tire boot and put that in my patch kit too. It will be hard to cut up one of my old ties, but I don't wear them anymore. We have gotten so informal.

I like those old Schwinn Super Record tires. I alway thought that they were made by National / Panasonic / Panasport and Panasport Pasela tires are my preference now. They may not be as flat resistant as certain Scwalbe and Continental tires, but they ride nice and I've had good luck with them.
