TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of October 23, 1972, in which you ask whether it is permissible under the Certification regulations for you to list alternative tire sizes and gross axle weight ratings on certification labels for vehicles which you sell without tires, but on which you apparently install them before delivery. You indicate that the tires are supplied by the customer, which he either owns, leases, or purchases from you.

Under the Certification regulation, you may if you wish list alternative tire sizes, and alternative gross vehicle or gross axle weight ratings, as you described in your letter. If you install the tires, regardless of whether they are owned by the vehicle purchaser, leased, or purchased from you, the tire you install should be one of the alternative sizes listed on the certification label.
