Hitting a large bump with year old radial tire caused it to form not just one but two bumps in the tire. The inner tube was fine when I swapped out tires, but the nylon cross supports going across the center had snapped to cause it to balloon like that. Made for a very interesting and bumpy ride. And yeah, I know I need to clean my workspace, it’s a bicycle shed outside, it’s not gonna be perfectly pretty haha.
