GENEVA, Switzerland (March 3, 2015) — Goodyear is offering a sneak peak this week at mobility concepts that offer the possibility of altering inflation pressure on demand and turning a tire into a battery charger.
Goodyear concepts offer enhanced mobility options
The tire automatically adjusts to three different inflation positions based on road conditions:
- Eco/Safety — maximum inflation in all three tubes for reduced rolling resistance;
- Sporty — reduced inflation in the inboard shoulder tube, enhancing dry handling through an optimized contact patch; and
- Wet Traction — maximized inflation in the center tube, improving aquaplaning resistance through a raised center tread.
The BHO3 concept generates electricity through the action of materials built into the tire that capture and transform the energy created by heat when it flexes as it rolls during normal driving conditions.
The materials used — described by Goodyear as “thermo-piezoelectric” material — would optimize the tire's electricity generation capabilities as well as its rolling resistance. Goodyear said the tire could convert both the tire's inherent thermal heat through a thermoelectric material, while the piezoelectric materials convert heat generated by the tire's rolling energy into electric impulses.
As demand for electric cars grows, this technology has the potential to reduce or even eliminate the vehicle-range anxiety motorists may have with electric cars.
The BHO3 also offers extended mobility through a self-supporting structure, Goodyear said,
Mr. Zekoski said concepts 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,” he said.
