Almost had a terrific blow-out today.
A few months ago, I got a set of Mr. Tuffy tire liners. My Panaracer Stradius tires were fairly inexpensive and, with a very soft center, are prone to cuts. But they are rated up to 150 psi, which makes me and my 250 lb butt feel just a bit more safe out there. The tire liners go inside the tire between the tire and the tube. When I would inflate the tire up to 120-130 psi though, it felt like it was sliding a bit on turns. Yes, I think I was feeling the tire liner slide against the tire or the tube, I don't think I was imagining it. When I would pump it up to 140 or 145, where I normally had it, it felt fine. This morning I got out the bike to ride to work and noticed a small line in one sidewall of the tire, all the way around. They're red, but this line was clearly black with the threads of the sidewall showing. The only thing I can attribute it to was the additional thickness of the liner. Maybe if I had kept the tire pressure a bit lower I would have been OK. A quick tire change took care of it. Can you imagine what kind of catastrophic tire failure I could have had on the way to work? Nice. I'm going to check on the tire tonight, maybe I can still use it. Probably not. The thing was only $18 or so and I had spare new tires laying around so I'm not too upset. Glad I caught it in time. You have been warned.
