Pub. L. 89-563, tit. 4, sec. 203

Sec. 203. In order to assist the consumer to make an informed choice in the purchase of motor vehicle tires, within two years after the enactment of this title, the Secretary shall, through standards established under title I of this Act, prescribe by order, and publish in the Federal Register, a uniform quality grading system for motor vehicle tires. Such order shall specify the date such system is to take effect which shall not be sooner than one hundred and eighty days or later than one year from the date such order is issued, unless the Secretary finds, for good cause shown, that an earlier or later effective date is in the public interest, and publishes his reasons for such finding. The Secretary shall also cooperate with industry and the Federal Trade Commission to the maximum extent practicable in efforts to eliminate deceptive and confusing tire nomenclature and marketing practices.
