About two weeks ago, I had a flat tire. Well, it wasn't flat, but it had very little air in it. It was a pain in the ass because I was worried it was going to go completely flat and I would have to learn how to change a tire by myself. I had to drive to campus and to class with my tire almost completely flat. I just didn't have time to put air in the stupid thing.
These tires would have made the stress I had two weeks ago go away. Bridgestone has created a new tire that is air-free. It's made of recyclable thermoplastic-resin spokes. They are immune to punctures.
