Why did my tire just blow up? I finished a 2 hour bike ride outside today, and I parked it next to the wall in my kitchen after I got home. 3-4 hours later... all the sudden the front tire just "blew up". What happened? Thanks!
Check the tire carefully for a split in the carcass. There may have been a small split starting to appear, and leaving the bike in a position where the sun could come through a window and hit the bike, may have caused the tire pressure to increase enough to extend a split in the carcass enough so that the tube was forced through the tire and it blew the tube. I had a bike in the basement do this same thing. I had changed the tube and didn't realize the tire had a small split in teh carcass. I aired the tire up to the maximum and set it aside. Apparently the sun coming in through a window had enough of an effect on the tire that it suddenly blew the tire right off of the rim!
