TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your November 1, 1976, letter to Mark Schwimmer of my staff, concerning the marking "V1" on passenger car tires.

The marking "V1" is not required by any Federal statute, motor vehicle safety standard, or other regulation to appear on the sidewall of passenger car tires. Furthermore, Section 103(d) of the National Traffic and Motor Vehicle Safety Act of 1966 as amended, 15 U.S.C. 1392(d), provides in pertinent part:

Whenever a Federal motor vehicle safety standard establshed under this title is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item of motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard.

This provision, considered with Federal Motor Vehicle Safety Standard No. 109, prohibits any State from imposing any safety labeling requirements for passenger car tires other than those contained in that standard. Any differing safety labeling requirements, including the "V1" that you have mentioned, are thus preempted and void.

SINCERELY,

NOVEMBER 1, 1976

Mark Schwimmer N.H.T.S.A. Office of Chief Counsel

The marking V1 on passenger car tires, as you know, signifies compliance to the "minimum performance requirements and uniform test procedures for new tires for passenger cars and station wagons" issued by the Vehicle Equipment Safety Commission on May 14, 1965 and later revised on October 11, 1965 and September 17, 1966.

To my knowledge no further revisions have been made, because the FMVSS 109 went into effect as of January 1, 1968. I assume, therefore, that the marking V1 should be applied only on the tires listed in the tables 1 - 6 of the regulation as follows: Table 1 - Domestic bias tires of the following series: Low Section (ex. 6.50-14) 4 & 8 P.R.

Super Balloon (ex. 6.70-15) 4 & 8 P.R.

Super Low Section (ex. 6.95-14) 4 & 8 P.R.

Table 2 - 70 Series, alpha numeric bias construction (ex. E 70-14) Table 3 - Domestic radial millimetric series from cross section Table 4 - European bias tires of the following series: Table 5 - European bias tires of the millimetric series (ex.

Table 6 - European radial tires of the millimetric series up to the cross section 155 (ex. 145 R 13) version A (32 psi)

I would like to know if the above is correct and therefore the marking V1 is no longer requested on the tires not included in this list.

If the requirements do not apply to every state in the United States, please notify me.

Thank you in advance for your reply on this matter.
