Self Regenerating Tires

Michelin have created some self regenerating tires which can go even longer then your long life ones. These new tires named the XDA5 feature 2 layers of traction. When the first layer wares out it reveals the second layer of tire. By doing this the tire can travel 30% further then before. Not only has the extra rubber been added, but also a new pattern which allows for better wear and tear by minimising wear patterns. A mixture of all this adds to a safer, longer and more stable tire. These tires are not available for your car though as they are for Class 8 rigs only. It would be cool to see this kind of idea make it to regular cars and no doubt in the future we will see tires increase in performance.
