A chemical company named CREAX did a promotional video 3 years ago for a self-repairing tire, but it has only gone viral now. Probably because it’s just too good to be true.
Watch a demonstration of their amazing bicycle tire driving over nails, and even being stabbed flat by hand, only to have every puncture instantly and perfectly sealed each time.
One of the youtube video comments had me curious. Just how much must this tire weigh?
