Tire is a great invention. Without the tire, the car will not be the same comfortable as it is nowadays. However, there is a company named Resilient Tech give us a new prototype which replaces the key part of tire with a non-pneumatic honeycomb structure.
I guess it won't be comfortable for most drivers, however, you don't need to worry about tire bursting.
