Rubber researchers may have finally fixed the flat tire - forever.
The tire revolution involves moving away from vulcanization, a method of heating rubber with sulphur to make it durable enough for the road.
Adding carbon and nitrogen allows rubber strands to meld back together after a puncture: just leave your tired tire to recuperate at room temperature for a week or so, and it's ready to re-inflate. So, you may still need to keep a spare on hand.

Right now, the new rubber is still a work-in-progress, so you can't put flats in your rearview mirror just yet.
