Goodyear wants your tires to charge your car

It's normal for one of Europe's big auto shows to host a variety of forward-thinking concept car reveals, but this year's Geneva Motor Show included a rarity — the unveiling of a pair of concept tires by Goodyear meant to expand ideas about what tires can do aside from keeping a car on the road.

The first, dubbed the BH-03, combines two fairly advanced technologies to generate electricity from the tire itself that could help recharge electric vehicle batteries on the road. A weave of thermoelectric fibers transforms the heat generated by the tire's friction with the road into energy, while piezioelectric material does the same using changes in the tire's shape as it moves. Goodyear didn't suggest how much energy such a set of tires could potentially create, but said if put into production could ease EV owners' range anxiety.
