Dear Mr. White: This responds to your June 7, 1977, letter asking who must mark a ri in accordance with the requirements of Standard No. 120, *Tire Selection and Rims for Motor Vehicles Other Than Passenger Cars*, in those cases where the rim is manufactured by one manufacturer and then supplied to a wheel manufacturer who welds the rim to a disk making a completed wheel.; The National Traffic Safety Administration has determined that the ri marking must be undertaken by the rim manufacturer. The rim manufacturer is best able to supply the required rim information and undertake the certification required by S5.2 of the standard. The subsequent addition of the disc to the rim should not alter the information marked on the rim.; Sincerely, Joseph J., Levin, Jr., Chief Counsel
