Standards Testing Laboratories Inc. (STL), the world's largest independent testing facility for tires, wheels, and related automotive components, has expanded its Rolling Resistance capabilities to test tires with up to 10,000 lb (4536 kg) of radial force. STL, which provides Rolling Resistance testing in accordance with SAE J1269 and ISO 28580 regulations, is capable of testing the latest tires on the market, such as single, wide-base tires used on commercial trucks. "There is a need in the industry to test these wide-base tires, which are increasingly being used in place of two standard tires on semi trucks and other commercial settings like cement trucks and waste haulers," said Cheryl Schnuth, Vice President, Marketing/Technical Sales, STL. "To answer the industry demand, STL upgraded our Rolling Resistance machinery and now offers accurate, efficient solutions for anyone who wants to run a wide-base tire or a single tire at a higher load." Based in Massillon, OH, STL operates testing facilities in Massillon and San Angelo, TX.
