Information Contained: • basic dimensions • week it was produced • types of materials used internally to reinforce the rubber • maximum inflation pressures and loads • certifies the tire meets industry standards and government regulations • not all information is branded on every tire
Tire Size – P215/65 R15 • Tire Type: Identifies vehicle type. P denotes passenger vehicle; LT denotes Light Truck. • Tire Width: Measured in millimetres. E.g. 215 • Aspect Ratio: The ratio of the height of the tire's cross-section to its width. E.g. 65 • Construction: R denotes radial, whereas B indicates a bias construction. • Wheel Diameter: The greatest distance across the wheel from tread to tread , measured in inches. E.g. 15
Load Index and Load Capacity • Load Index: The maximum load in pounds (lb.) that the tire can support when properly inflated based on the Load Index Chart. E.g. 89
Speed Rating • Speed Rating: Indicates the maximum service speed for the tire based in the speed-rating chart. E.g. " H " indicates a maximum tolerable speed of 210 km/h (130 mph).
UTQG Rating • UTQG stands for Uniform Tire Quality Grading. • based on treadwear, traction and temperature capabilities
Treadwear • based on the wear rate of the tire • E.g. a tire with a 200 treadwear rating would wear twice as long as a tire with a 100 rating.
Traction and Temperature • Traction Grades: Identify the tire's ability to stop on wet pavement E.g. Traction A • AA: Very Best • A: Best • B: Intermediate • C: Acceptable • Temperature Grades: Denote the tire's resistance to the generation of heat. Excessive temperatures can lead to tire failure. E.g. Temperature A • A: Best • B: Intermediate • C: Acceptable
Severe Snow Tires • A mountain/snowflake symbol branded on the tire's sidewall identifies tires that met the required performance in snow testing. • M+S (Mud + Snow): Indicates this is an all-season tire.
Tire Identification Number • Tires sold in Canada have a number with information about when and where the tire was produced. • Example: • B3 : Indicates the manufacturer and plant code • CD : Tire size code • E52X : Optional • 2602 : Week and year of manufacture (in this example the 26th week of 2002) • The maple leaf symbol indicates this is a Canadian made tire and certifies that it meets all of Transport Canada's requirements.
Load & Pressure Marking • Tire pressures are normally measured in "pounds per square inch" (psi), Kilopascals (kPa), or bars of pressure (bars: • MAX. LOAD 630 kg (1389 lbs)MAX. PRESSURE 300 kPa (44 psi)
