TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your January 21, 1976, request for an interpretation of Federal Motor Vehicle Safety Standard No. 117, Retreaded Pneumatic Tires.

You asked whether a retreaded tire may be manufactured with a casing from which the original manufacturer's tire identification number (required by 49 CFR Part 574 and Standard No. 109) has been buffed off, provided the original DOT symbol remains. The answer to your question is yes. The only items of information that are required to be retained from the original casing are the following:

(a) the symbol DOT;

(b) the size of the tire; and

(c) the actual number of plies or ply rating.

A retreaded tire must also, of course, be labeled with the DOT-R symbol and with the retreader's tire identification number, pursuant S6.1 of Standard No. 117 and 49 CFR Part 574.
