TITLE: FMVSS INTERPRETATION

TEXT:

This is in reply to your letter of May 28, 1973, asking whether you may, consistently with Federal Motor Vehicle Safety Standard No. 109, label maximum load and maximum permissible inflation pressure as follows, using the 165 SR 15 tire size designation as an example:

1. Max Load 1200 Lbs. At 36 psi

2. Max Load 1200 Lbs. At Max Press 36 psi

We do not believe alternative 1 to be consistent with Standard No. 109 because it is not clear that 36 psi is the maximum permissible inflation pressure. Alternative 2 does so indicate, however, and we believe that alternative to be consistent with the standard.

Yours truly,

Secretary of Transportation National Highway Safety Bureau, US Department of Transportation

MVSS 109

Dear Sirs;

Please inform us if we are allowed to use this alternative labelling on our tires, i.e. on tire size 165 SR 15:

Alternative 1: "Max Load 1200 Lbs AT 36 psi"

Alternative 2: "Max Load 1200 Lbs At Max Press 36 psi"

Yours sincerely, TRELLEBORGS GUMMIFABRIKS AKTIEBOLAG Tire Research --
