TIRE BALANCING: When there is an unequal distribution of tire weight, the act of adding external weights in order to achieve equal weight distribution and improved ride is known as tire balancing.
TIRE CHAIN: A flexible, metal chain that attaches to the tire for enhanced traction on snow or ice.
TIRE CUPPING (or Tire Scalloping): An irregular tire wear pattern where a type of uneven tire wear where a series of abnormally worn patches will be mixed in among less worn parts on the tread of the tire. For more information, read our article around Tire Cupping.
TIRE FEATHERING (or Tire Scuffing): A common tire wear pattern that occurs when a tire wears down at an angle, where one side of a tire rib or tread block wears lower or smoother than the other. For more information, read our article around Tire Feathering.
TIRE PRESSURE GAUGE: A tool used to measure a tire's air pressure properly.
TIRE PRESSURE MONITORING SYSTEM: An automated system that monitors the air pressure in a vehicle's tires in order to alert the driver when the pressure drops below a pre-determined level. Learn more about the importance of a Tire Pressure Monitoring System and how to have it serviced.
TIRE REVS PER MILE: Number of tire revolutions per one mile at rated load and inflation; also called rpm.
TIRE SECTION WIDTH: The width of the tire from sidewall to sidewall.
TIRE SIZE CALCULATOR: A calculator tool that compares the measurements of two tires' diameter, width, sidewall, circumference, and revolutions per mile.
TIRE SIZE NOMENCLATURE: The system designating the tire size along with other information on the particular tire, which may include intended service type, nominal section width, nominal aspect ratio, construction, rim diameter and load capacity. There are various forms of size nomenclature such as P-metric, LT-metric, hard metric, alphanumeric and LT flotation. This code can be found on the sidewall of each tire and might look something like "245/65R17".
TIRE TYPE MARKING IN THE TIRE SIZE: A "P" designation means that it is a passenger car tire. An "LT" designation means that it is a light truck tire.
TRACTION: The grip or friction between the tires and the road surface.
TREAD: The part of the tire that comes into contact with the road surface.
TREAD DEPTH: The distance measured from the tread surface to the bottom of the grooves in a tire.
TREADWEAR INDICATORS: Raised bars of rubber molded at a height of 2/32 across the bottom of the tread grooves on a tire. When the tread wears down to these bars, the tires should be replaced.
TREAD WEAR: The loss of tread depth as a tire is in service. Proper maintenance of your vehicle and tires, including maintaining proper inflation pressure, will result in even tread wear and will extend the useable tread life of the tires.
