Last night I biked up to my friends game night. After I had been there for 1 or 2 hours, with the bike just sitting outside, we hear this loud popping noise. I bikes tire had just popped, and this tire was just put on last month, and had no patches on it. Well when I took it apart, it popped where the valve came out of the tube itself, is where the failure point was. It just does not make much since, because the tire pressure was set at 80psi, and the tires are rated from 55psi to 85psi. The bike was sitting out in the cold, so the air should have been contracting so the pressure should have gone down a bit, yet the tire popped.
