AN EVALUATION OF THE UNIFORM TIRE QUALITY GRADING STANDARDS AND OTHER TIRE LABELING REQUIREMENTS. FINAL REPORT

The Uniform Tire Quality Grading Standards (UTQGS) (575.104) were designed to assist consumers in making informed choices by requiring information be provided on passenger car tires about their relative performance in the areas of treadwear, traction, and temperature resistance. Federal Motor Vehicle Safety Standards (FMVSS) 109, 117, and 119 require size, content, care, and certification information be molded into pneumatic tires and retreads. This study evaluates whether four groups of potential information users knew about, understood, and used the information. The study was based on telephone surveys of individuals who buy tires for their own vehicles, individuals who buy tires for fleets of vehicles, tire sellers, and tire repairers. The individual consumers had either bought tires six or less months prior to the contact (recent consumers) or planned a purchase within two months of the contact (prospective consumers). The principal findings are as follows: (1) Most consumers knew FMVSS, but not UTQGS, information is found on tires. Most sellers and repairers knew the location of both. (2) When presented with multiple choice questions, most respondents in all groups chose the correct definition of temperature resistance rating and the relative ranking of two traction grades. Less than half the consumers chose the correct definition of traction rating. (3) Prospective consumers rated significantly more UTQGS and FMVSS items important in influencing their tire choices than recent consumers (three UTQGS and eight FMVSS items vs one FMVSS item).
