Mighty Morphin’ tire technology on future Mazda RX-9

The Mazda RX-9 is an advanced concept that came out on top in this year’s Michelin Design Challenge.

Mazda’s tires will feature Electroactive Polymers (E.A.P.) that with varying levels of voltage from the vehicle’s electrical system can actually change the shape and depth of their tread pattern. The rubber donuts can go from flat and smooth to knobby and grippy, or even ride high on their centers for ultra-low rolling resistance.
