North America's largest tire maker was selected to provide its Goodyear Integrity tires for the 2005 Prius. The tires are designed to offer a smooth ride -- essential to the fuel efficiency targets of the vehicle.

The Prius, which qualifies as a "hybrid" vehicle, powered by both an electric motor and a gasoline engine, has an EPA-estimated combined city/highway average rating of 55 miles per gallon.

Driving the car at low speeds and by assisting the gas engine during acceleration the battery-powered motor helps save fuel and reduce emissions. No plug-in is required as coasting and decelerating recharge the motor's batteries.

The Prius, now has a decent set of tires -- P185/65R15 Goodyear Integrity. Built to favor fuel economy over luxurious touring or sporty auto crossing, the Goodyear tires roll quietly down the road and generate 0.76 g of sideways stick in the corners and 0.89 g in a straight line under braking.

To draw attention to the increasing performance capabilities of today's hybrid vehicles a specially designed Prius set a hybrid vehicle land speed record at the legendary Bonneville Salt Flats in Utah, topping 130 miles per hour.

I t must be noted that Prius used unique 26-inch front and 25-inch rear Goodyear Eagle race tires to accomplish the high speed mark. Goodyear tires are original equipment on many vehicles from Cadillac, Chrysler, Ford, GMC, Honda, Hummer, Infiniti, Jeep, Isuzu, Lexus, Acura, Mazda, Mercury, Chevrolet, Nissan, Land Rover and Toyota.

The Prius-Goodyear connection also has worked well in an application far different from what drivers of the hybrid car will experience on normal streets and highways.
