I had hear that tire overheating occurs on mountains, but didn't know it could happen on hills.
I was going down one of the steepest hills around here on my mostly-road bike. Just coming out of a cold, and not feeling physically brave, I pretty much rode my front brake down. The hill is very steep, and I was still going about 15 even with the brake. Its about a quarter mile down the hill. Just as I got to the bottom and was lining up with traffic, my front tire flatted.
I didn't find any debris in the tire, and I replaced the tube. When I got home I opened it up. The plastic rim strip had little depressions at each spoke well. On one of them (presumably the one that caused the flat), the rim strip had broken through.
So, my questions are: Can I short but steep hill cause enough heating to overheat a tire/tube? And, would it help to use cloth rim strips?
