Michelin XDA5 Tires Extend Big-Rig Tread Life

Michelin's XDA5 tires are being promoted as "self-healing" or "regenerating," but that's a bit generous. Instead the tires reveal new grooves and tread was they wear down, extending the usable life of tires by 30% before they must be retreaded.

The XDA5 series is designed for big rigs and over over-the-road haulers; you won't be using these on your Prius for a while. (Unless you're building a Monster Prius.)
