This specification covers the design and construction standards, material and physical requirements, and test methods for a special purpose smooth-tread standard tire utilized on fixed braking slip continuous friction measuring equipment such as the runway friction tester, surface friction tester, or BV-11 skiddometer trailer for measuring tire-pavement friction forces. When tested with appropriate methods, the tread compounds shall conform to specified values of physical properties such as tensile sheet cure, 300 % modulus, specific gravity, tensile strength, elongation, and tire tread durometer performance.
