Dear Mr. McCollum:
Thank you for your inquiry on behalf of your constituent, Mr. Perry Faulkner. Mr. Faulkner requested a written interpretation about whether casings imported into this country are required to have the "DOT number." A "casing" means a used tire to which additional tread may be attached for the purpose of retreading. As explained more fully below, casings for retreaded passenger car tires must have the DOT symbol, but casings for tires for use on vehicles other than passenger cars (referred to as "truck tires" in this letter) are not required to have the DOT symbol.
At the outset, I note that Mr. Faulkner's letter stated that the "DOT number" on a tire indicates that the Federal excise tax has been paid. That statement is inaccurate. The "DOT number" on a tire only represents the manufacturer's or retreader's certification of compliance with this agency's standards and regulations. If Mr. Faulkner wants further information about Federal excise taxes on tires, he may wish to contact the Internal Revenue Service, since that agency administers the Federal excise taxes.
Mr. Faulkner is mixing two different types of markings when he refers to a "DOT number." The first type of marking is the symbol "DOT." This marking by a tire manufacturer or retreader on a tire is a certification that the tire complies with an applicable Federal motor vehicle safety standard. Federal safety standards applicable to tires include Standard No. 109 for new passenger car tires, Standard No. 117 for retreaded passenger car tires, and Standard No. 119 for new truck tires.
Standard No. 117 (the retreaded passenger car tire safety standard) includes a requirement that all passenger car tire casings to be retreaded must include the symbol "DOT." See S5.2.3(a). Therefore, it is illegal to sell or import into this country any passenger car tire casings that are not marked with the symbol "DOT." However, none of our Federal safety standards set forth requirements for retreaded truck tires. Since there is no standard for retreaded truck tires, there is no requirement that casings for retreaded truck tires be marked with the DOT symbol. I have enclosed a June 18, 1981 letter to Mr. Roy Littlefield that offers a more detailed discussion of this issue.
The second type of marking to which Mr. Faulkner referred was the tire identification number specified in Part 574. This number identifies the manufacturer or retreader of the tire, along with the date of manufacture or retread and other attributes of the tire. A tire identification number is not required on any casing: Standard No. 117 does not require this marking on passenger car casings, and as explained above, there is no Standard for casings for truck tires. Please note, however, that Part 574 requires all finished retreads, including retreaded truck tires, to be marked with the retreader's identification number.
I hope this information is helpful. Please let me know if you have any further questions or need some additional information on this subject.
Sincerely,
Jamie McLaughlin Fish Director, Intergovernmental Affairs
