MUNICH—Resistance to wear and the generation of rubber-particle emissions are now key performance criteria for tire manufacturers—as evidenced by recent announcements from Michelin and Sumitomo Rubber Industries.
Both manufacturers referenced a testing program involving almost 100 different summer and winter tires, conducted by the Munich-based German Automobile Club (ADAC).
For the tests, ADAC subjected tires to 15,000 km (9,320 miles) of real-life driving on a mixture of urban, country and motorway roads to calculate the life of the tire.
Data on abrasion rates, tread depth when new and the amount of material shed by the tires was used to evaluate performance.
Tire performance characteristics were also assessed to give a clear understanding of any compromises which may be involved in choosing a more "environmentally-friendly" tire.
