How did my inner tube get folded in a Z inside the tire? My rear tire was keep going flat while riding, so I felt around the tire for any punctures or abnormal ‘signs’ that may be causing the problem.
One area felt too thick, and at first, I thought I just overinflated it and somehow the air got trapped. Later, I ended up pushing my bike into the rocks, and when the tire tread came off, I saw that the inner tube had literally folded up into a ‘Z’ shape inside the tire. How did this happen? I have never seen anything like this before.
Most likely incorrect tube and tire combo. Check your tube range if it matches the size of your tire. Could also be that you seated the tire incorrectly.
