Dear Mr. Hayashi: This is in response to your letter of March 26, 1981, requesting, (sic an interpretation of the Uniform Tire Quality Grading (UTQG) Standards (49 CFR S575.104). You ask whether a tire designed for service as a temporary use spare tire, and labeled on its sidewall with the inscription: TEMPORARY USE ONLY FOR SPARE TIRE, INFLATE TO 40 PSI, MAX. SPEED 50 MPH, is exempt from the requirements of the UTQG Standards.; As you note, the 'Application' section of the UTQG regulation does no apply to space-saver or temporary use spare tires. Thus, the UTQG Standards would not apply to the tire you describe, which is designed as a temporary use spare tire and is so labeled.; Sincerely, Frank Berndt, Chief Counsel
