https://www.cnet.com/roadshow/news/michelin-gm-future-tires/ I think it's the next BIG breakthrough in vehicles. Imagine no more flats. (most new cars have no spare). No air pressure monitoring and filling, better low rolling resistance, more miles out of your tires, less bump going over pot holes and speed bumps and no accidents from an out of control car with a flat. I already have air free tires on my citizen bike, Specialized has air free tires on their alibi model bike, Polaris has air free tires on their ATV. What do you think?
