TEXT: Re: Farm Use Only Tires and Request for Interpretation of Standard No. 109

Thank you for your reply to our letter of December 11, 1969 concerning tires marked with the legend "Farm Use Only Tires".

Concerning the questions you raise in your letter relating to the DOT symbol, Standard No. 109 requires that the symbol be between the maximum section width and the bend to protect the lettering from obliteration during use. Therefore, placing the DOT symbol at the widest place on the side wall rib as illustrated in your enclosed drawing would not be permitted.

With regard to your question asking if the approved symbol and the manufacturer's code mark is necessary, the approved symbol signifies that the manufacturer certifies that the tire complies with the Standard and is, therefore, necessary. Tires exported to this country without the symbol would be in violation of the National Traffic and Motor Vehicle Safety Act of 1966. The code number is only required if your company manufactures a tire with a brand name other than its own. The purpose of the code number is to identify the manufacturer of the tire.
