If the energy regeneration from the wheel rotation, frictional forces, or heat from the exhaust fumes are no longer sufficient, then the renowned tire manufacturer, Goodyear creates a new breakthrough. At the Geneva Motor Show 2015, they introduced a new type of tire named BH-03 that is capable of generating electricity to help the battery activates a number of car components.

With thermo-piezoelectric technology which contained in the tire, the heat that generated due to the tire rotation is used to recharge the batteries for hybrid or electric cars. Not only that, the tires can also absorb the heat from the sun even when parking though to be converted into electricity.
This theory is good, but some technology observers actually smirked. It is said that the energy produced is small. However Goddyear reverse the situation by saying that there are better small energy produced than nothing.

Another concept presented is TripleTube. It is a tire with three layers having different wind pressure. Its function is the tire can adjust to road conditions based sensors. For example, when the roads are wet, one layer will be inflating the middle tread portion so that the possibility of aquaplanning increasingly thin.
