About Us

Standards Testing Laboratories, Inc. (STL), located in Massillon, Ohio, was founded by R.L. "Dick" Fuller in 1971. The company began as an independent laboratory with one four-position roadwheel machine, operating out of a trailer office.

By 1975, eight four-position machines operated at STL. Today, more than 100 test positions run 24 hours a day, 365 days per year.  The laboratory has grown to three testing divisions located on a 10 acre complex of offices and testing facilities. 

STL now operates the world's largest independent dynamic testing facility for tires, wheels, and related automotive components, providing the rubber and automotive industries with dynamic laboratory testing, static and physical testing, fleet testing, and test machines.

The company's roots were established in developing and manufacturing evaluation equipment for the automotive industry in compliance with the federally mandated regulations set in the late '60s and early '70s. A logical and planned progression from manufacturing to product testing provided the connection and entry in the automotive evaluation market.

As early as 1980, STL provided the tire and automotive industry with a wide range of dynamic vehicle data acquisition. In its long history of testing experience, STL has satisfied a multitude of demanding customers with standardized product tests and the development of special tests to meet individual needs. Some of these customers have included GM, Ford, Chrysler, Alcoa, ECE, DOT, Yokohama, and NASA.

STL continues to meet its customers' needs for accurate, high-quality testing, fast response, and professional consulting through any of its three divisions.
