Wheels and Tires*Treadwear The treadwear gradeis a comparative rating based onthe wear rate of the tire whentested under controlled conditionson a specified government testcourse. For example, a tire graded150 would wear 1½ times as wellon the government course as a tiregraded 100.*Traction: The traction grades,from highest to lowest are AA, A,B, and C. The grades represent thetire's ability to stop on wetpavement as measured undercontrolled conditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.*Temperature: The temperaturegrades are A (the highest), B andC, representing the tire'sresistance to the generation ofheat and its ability to dissipateheat when tested under controlledconditions on a specified indoorlaboratory test wheel.M. Maximum InflationPressure: Indicates the tiremanufacturers' maximumpermissible pressure or thepressure at which the maximumload can be carried by the tire. Thispressure is normally higher thanthe vehicle manufacturer'srecommended cold inflationpressure which can be found onthe Safety ComplianceCertification Label (affixed toeither the door hinge pillar,door-latch post, or the door edgethat meets the door-latch post,next to the driver's seatingposition), or Tire Label located onthe B-pillar or the edge of thedriver's door. The cold inflationpressure should never be set lowerthan the recommended pressureon the vehicle label.The tire suppliers may haveadditional markings, notes orwarnings such as standard loador radial tubeless.Additional InformationContained on the Tire Sidewallfor LT Type TiresNote: Tire Quality Grades do notapply to this type of tire.AE142544DBBLT type tires have some additionalinformation beyond those of Ptype tires.
