TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of March 20, 1973, in which you ask whether, if a retreaded tire cannot meet the dimensional requirements for its original casing size, it can be considered as and labeled with a smaller size, if it meets the dimensional requirements for the smaller size.

S5.1.4 of Standard No. 117 prohibits a retread tire from having a size designation, maximum load rating, or maximum inflation pressure greater than that originally specified on the casing. It does not prohibit a retreaded tire from having a smaller size than its casing, as long as the retreaded tire meets all the requirements for its labeled size designation.
