Uniform Tire Quality Grading (original) (raw)
Le classement uniformisé de la qualité du pneu Uniform Tire Quality Grading (UTQG) est un jeu de qualifications standardisées de trois caractéristiques des pneus : l’usure de la bande de roulement (treadwear), la résistance en température et la traction. L’UTQG a été créée par la National Highway Traffic Safety Administration en 1978.

| dbo:abstract | Le classement uniformisé de la qualité du pneu Uniform Tire Quality Grading (UTQG) est un jeu de qualifications standardisées de trois caractéristiques des pneus : l’usure de la bande de roulement (treadwear), la résistance en température et la traction. L’UTQG a été créée par la National Highway Traffic Safety Administration en 1978. Depuis le 31 mars 1979, tous les pneus destinés à être vendus aux États-Unis doivent faire apparaître leur classement UTQG sur leur flanc pour une utilisation légale sur voie publique.Il ne faut pas confondre UTQG et les caractéristiques du pneu qui sont d’autres informations de dimensions et de capacités. Il est à noter que le classement UTQG d’un pneu est déterminé par le fabricant du pneu ou autre organisme ou entreprise indépendant grâce à leurs propres résultats de tests. Toutefois, la NHTSA peut inspecter les données concernées. D’autre part, les pneus hiver, ou pneus « neige », n’ont pas d’obligation de marquage UTQG.Il en est de même pour les pneus de moto, de bus, de certains types de camion et de remorque. (fr) Uniform Tire Quality Grading, commonly abbreviated as UTQG, is the term encompassing a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in 1978, a branch of the United States Department of Transportation (DOT). All tires manufactured for sale in the United States since March 31, 1979 are federally mandated to have the UTQG ratings on their sidewall as part of the DOT approval process, in which non-DOT approved tires are not legal for street use in the United States. It is not to be confused with the tire code, a supplemental and global standard measuring tire dimensions, load-bearing ability and maximum speed, maintained by tire industry trade organizations and the International Organization for Standardization. The National Highway Traffic Safety Administration (NHTSA) established the Uniform Tire Quality Grading Standards (UTQGS) in 49 CFR 575.104. When looking at UTQG ratings it is important to realize that the Department of Transportation does not conduct the tests. The grades are assigned by the tire manufacturers based on their test results or those conducted by an independent testing company they have hired. The NHTSA has the right to inspect tire manufacturers' data, and can fine them if inconsistencies are found. The NHTSA published DOT HS 812 325 “Consumer Guide to Uniform Tire Quality Grading” August 2016, which provides rating information. Dedicated winter tires, also known as snow tires, are not required to have a UTQG rating. Non-passenger car tires, such as those for motorcycles, buses, medium trucks and above along with trailers are also not required to have a UTQG rating, although FMVSS Standard 109 requires the following to be listed on the tire's sidewall: speed restriction if less than 55 mph, regroovable if designed for regrooving, and a letter designating load range rating.
