Michelin has created a new tire as part of the development of the Peugeot 308. The Energy Saver uses a specially-developed rubber composite, and Michelin claims the tire reduces rolling resistance by 20% in both 15- and 16-inch sizes. Tire testing was carried out by TÜV SÜD Automotive, which measured the Michelin's performance to that of the top six competitor tires. The Energy Saver is also said to have the same durability as Michelin's other tires.
The tire will come standard on two 308 models, the 90 HDI and the 110 HDI 308s, both high mileage diesels, and Peugeot will be the exclusive maker to use it until February 2008. In addition to the gas savings because of its lower rolling resistance, the tire is also said to lower a car's CO2 emissions by 4g per kilometer. We'll find out soon enough if the claims have real-world merit -- and real world savings -- but we welcome all such efforts where the rubber meets the road.
