Two groundbreaking concept tyres unveiled by The Goodyear Tire & Rubber Company at the 85^th Geneva Motor Show could radically change the role of car tyres in the future. Although the two tyres are concept products, the futuristic technologies stretch the imagination and provide a glimpse of what practical innovations may be on the horizon.

The first concept - named 'BHO3' - offers the possibility of charging the batteries of electric cars by transforming the heat generated by the rolling tyre into electrical energy. This tyre generates electricity through the action of materials in the tyre that capture and transform the energy created by heat when it flexes as it rolls during normal driving conditions.

As demand for electric cars grows, this technology has the potential to significantly contribute to the solution of future mobility challenges. This visionary tyre technology could eliminate the vehicle-range anxiety motorists may have with electric cars.

The second concept - named 'Triple Tube' - contains three internal tubes that adjust tyre inflation pressure in response to changing road conditions, delivering new levels of performance and versatility.

Tubes are located beneath the tread and near the inboard and outboard shoulders of the tyre as well as the centre. The tyre relies on an internal pump that moves air from the main air chamber to the three individual air chambers, or tubes. The tyre automatically adjusts - on its own - to three different positions based on road conditions - the Eco/Safety position, the Sporty position and the Wet Traction position.
