Two ground-breaking concept tyres unveiled by The Goodyear Tire & Rubber Company at this week’s 85th Geneva International Motor Show could radically change the role of car tyres in the future.
Though 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. The second concept – named “Triple Tube” – contains three tubes that adjust tyre inflation pressure in response to changing road conditions, delivering new levels of performance and versatility.
“These concept tyres reimagine the role that tyres may play in the future,” said Joe Zekoski, Goodyear’s senior vice president and chief technical officer. “We envision a future in which our products become more integrated with the vehicle and the consumer, more environmentally friendly and more versatile.”

BHO3

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. The materials used would optimise the tyre’s electricity generation capabilities as well as its rolling resistance.
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.

This tyre features three internal tubes within the tyre. 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 – 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 maximised inflation in the centre tube – provides high aquaplaning resistance through a raised tread in the centre of the tyre.
Although these tyres are future concepts, Zekoski says they represent an essential aspect of Goodyear’s innovation strategy, instilling a forward-looking, market-back mindset in the company’s research and development teams.
“It is more important than ever for us to stay firmly rooted in our market-back innovation process, which calls on us to focus on, and anticipate, the rapidly evolving needs of our customers,” said Zekoski.
Goodyear is one of the world’s largest tyre companies. It employs approximately 69,000 people and manufactures its products in 51 facilities in 22 countries around the world. Its two Innovation Centres in Akron, Ohio and Colmar-Berg, Luxembourg strive to develop state-of-the-art products and services that set the technology and performance standard for the industry.
