Unveiled at the recent Geneva Motor Show, two concept tyres by 843 Goodyear could radically change the role of car tyres in the future according to the company.

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, Triple Tub, contains three tubes that adjust tyre inflation pressure in response to changing road conditions, delivering new levels of performance and versatility.

The BHO3 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 tire’s electricity generation capabilities as well as its rolling resistance.

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

Triple Tube features three internal tubes 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.

“These concept tyres re-imagine the role that tires 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.”

    The Oregon Department of Transportation (ODOT) is undertaking a pilot project to test the next generation of a road usage charge system designed to address funding gaps caused by a rise in fuel efficiency and a decline in gas tax revenue. Around forty volunteers have begun testing the new system, where, instead of paying the gas tax, automatically added at the pump, pilot participants will pay a per mile charge based on the number of miles they drive. The charge is roughly equal to the amount of gas tax the

    Two decades after the death of the inductive loops was predicted, Matt Zinn, technical services manager at Eberle Design says the technology still offers advantages. More than 20 years ago the emergence of video detection systems led many to foretell the end of inductive loops. In the intervening years advocates of radar, infrared and wireless detection technologies have also claimed that loops were on their way out. But in fact, by all calculations, the use of loops has actually increased and although
