This morning I heard the tube in the rear tire explode (I never heard a tube explode before. It was quite loud). I hope someone can shed some light on why this may have happened (and how to prevent it).
- The bike was inside a house and nobody had touched it for 12 hours.
- It is a road bike. The tire says pressure should be between 90 and 125 PSI, and just yesterday I inflated it to 110 PSI and after that went for a ride just fine.
- The tube was very new, it had only 4-5 days.
- The tube has a small hole is one of the sides. The tire has a little crack on that spot. It is very thin and about 0.5cm (0.2 inches) long. The rim seems fine.
- The tire was still in place, it did not come off of the rim.
- Two weeks ago it happened with another fairly new tube. That time I didn't hear the explosion, but one morning I found the tire deflated without explanation. Both tubes have the hole in exactly the same place, so I guess the cause is related.
- 10 minutes before it exploded, I opened a door-window next to it, so the temperature dropped a bit suddenly. However, I'm in California so the temperature is very mild. It's not cold at all.
- The bike is in the sun during the day.
