The Office of Vehicle Safety Compliance (OVSC) provides contractor laboratories with Laboratory Test Procedures as guidelines for obtaining compliance test data. The data are used to determine if a specific vehicle or item of motor vehicle equipment meets the minimum performance requirements of the subject Federal Motor Vehicle Safety Standard (FMVSS). The purpose of these OVSC Laboratory Test Procedures is to present a uniform testing and data recording format, and provide suggestions for the use of specific equipment and procedures. These Laboratory Test Procedures do not constitute an endorsement or recommendation for use of a any product or method. If any contractor views any part of the OVSC Laboratory Test Procedures (TP) to be in conflict with a FMVSS or observes deficiencies in a TP, the contractor is required to advise the Contracting Officer's Technical Representative (COTR) and resolve the discrepancy prior to the start of compliance testing. This standard applies to new pneumatic bias ply and certain specialty tires, specifically new pneumatic radial tires for use on passenger cars manufactured before 1975, new pneumatic bias ply tires, and ST, FI, and 8-12 rim diameter and below ties for use on passenger cars manufactured after 1948. (S2) FMVSS No. 109 specifies laboratory test requirements for physical dimensions (S4.2.2.2), bead unseating resistance (S4.2.2.3), tire strength (S4.2.2.4), endurance (S4.2.2.5), and high speed performance (S4.2.2.6); defines performance requirements (S4.2) including general requirements (S4.2.1) and test requirements (S4.2.2) as well as tire load ratings; and specifies labeling (or marking) requirements (S4.3). FMVSS No. 109 does not apply to any tire that has been altered so as to render impossible its use, or its repair for use, as motor vehicle equipment.
