Dear Mr. Eddy: This is in response to your letter of March 7, 1980, asking whethe ASTM E501 and E524 tires must be graded in accordance with the Uniform Tire Quality Grading (UTQG) Standards (49 CFR 575.104). You state that these tires are manufactured in limited quantities as standards for traction testing and are not manufactured for general highway use. It is the National Highway Traffic Safety Administration's understanding that these tires are used only on a test trailer designed for use in skid testing.; The UTQG regulation applies to new pneumatic tires for use on passenge cars (49 CFR 575.104(c)(1)). Thus, ASTM E501 and E524, which are manufactured solely for use on a traction test trailer, would not fall within the application of the UTQG Standards.; Sincerely, Frank Berndt, Chief Counsel
