Two new Goodyear Concept tyres have been showcased, and claim to deliver ‘smart, safety driven and sustainable solutions to the car industry’.
This tire generates electricity through the action of materials in the tire that capture and transform the energy created by heat when it flexes as it rolls during normal driving conditions. The materials used would optimize the tire’s electricity generation capabilities as well as its rolling resistance. Goodyear believes that as demand for electric cars grows, this technology has the potential to significantly contribute to the solution of future mobility challenges, as well as eliminate the vehicle-range anxiety motorists may have with electric cars.
This tire features three internal tubes within the tire. Tubes are located beneath the tread and near the inboard and outboard shoulders of the tire as well as the center. The tire relies on an internal pump that moves air from the main air chamber to the three individual air chambers, or tubes. The tire automatically adjusts – on its own – to three different positions based on road conditions.
The Eco/Safety position – with maximum inflation in all three tubes – offers reduced rolling resistance.
The Sporty position – with reduced inflation within the inboard shoulder tube – gives drivers dry handling through an optimized contact patch.
The Wet Traction position – with maximized inflation in the center tube – provides high aquaplaning resistance through a raised tread in the center of the tire.
