Goodyear has totally rethought tire replacement with the ReCharge tire concept.
Goodyear imagines feeding the tires pills to regenerate tire tread.
Specific pills give the tire a different tread, say for changing weather, or a personalized blend for a driver.
The tread itself is made from a material inspired by spider silk.
Not only is the material sustainable, but the tire is totally biodegradable.
It's a low-maintenance process, but this kind of technology is nowhere near ready for production.
One can only dream it'll be this easy one day.
