Goodyear at the Geneva auto show unveiled a new SUV tire concept that’s specifically crafted to deal with multiple types of terrain while improving fuel efficiency, CNET reports. The tire has two rings, each serving a different purpose — a main outer ring that takes up two-thirds of the tire’s width and is used for regular day-to-day driving on regular roads, and an inner one that takes up the rest and is used for off-road action. The outer ring is slightly bigger in diameter than the inner one, and “has primarily a slick surface with cut-ins to move water and prevent hydroplaning,” but also different textured surfaces to enhance grip. The inner ring has “more aggressive cut-ins and pebbly surfaces”
