Tire Terminology and Definitions
Air Pressure:The amount of air inside thetire pressing outward on each square inch of thetire. Air pressure is expressed in pounds persquare inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combinedweight of optional accessories. Some examples ofoptional accessories are, automatic transmission,power steering, power brakes, power windows,power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s heightto its width.
Belt:A rubber coated layer of cords that is locatedbetween the plies and the tread. Cords may bemade from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrappedby steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the pliesare laid at alternate angles less than 90 degreesto the centerline of the tread.
Cold Tire Pressure:The amount of air pressure ina tire, measured in pounds per square inch (psi) orkilopascals (kPa) before a tire has built up heatfrom driving. SeeInflation - Tire Pressure onpage 6-54.
Curb Weight:The weight of a motor vehicle withstandard and optional equipment including themaximum capacity of fuel, oil, and coolant,but without passengers and cargo.
DOT Markings:A code molded into the sidewallof a tire signifying that the tire is in compliancewith the U.S. Department of Transportation (DOT)motor vehicle safety standards. The DOT codeincludes the Tire Identification Number (TIN),an alphanumeric designator which can also identifythe tire manufacturer, production plant, brand,and date of production.
GVWR:Gross Vehicle Weight Rating. SeeLoading the Vehicle on page 5-18.
GAWR FRT:Gross Axle Weight Rating for thefront axle. SeeLoading the Vehicle on page 5-18.
GAWR RR:Gross Axle Weight Rating for therear axle. SeeLoading the Vehicle on page 5-18.
Intended Outboard Sidewall:The side of anasymmetrical tire, that must always face outwardwhen mounted on a vehicle.
Kilopascal (kPa):The metric unit for air pressure.
Light Truck (LT-Metric) Tire:A tire used onlight duty trucks and some multipurpose passengervehicles.

Treadwear Indicators:Narrow bands, sometimescalled wear bars, that show across the tread ofa tire when only 1/16 inch (1.6 mm) of treadremains. SeeWhen It Is Time for New Tires onpage 6-64.
UTQGS (Uniform Tire Quality GradingStandards):A tire information system thatprovides consumers with ratings for a tire’straction, temperature, and treadwear. Ratings aredetermined by tire manufacturers usinggovernment testing procedures. The ratings aremolded into the sidewall of the tire. SeeUniformTire Quality Grading on page 6-67.
Vehicle Capacity Weight:The number ofdesignated seating positions multiplied by 150 lbs(68 kg) plus the rated cargo load. SeeLoadingthe Vehicle on page 5-18.
Vehicle Maximum Load on the Tire:Load on anindividual tire due to curb weight, accessoryweight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached toa vehicle showing the vehicle’s capacity weightand the original equipment tire size andrecommended inflation pressure. See “Tire andLoading Information Label” underLoadingthe Vehicle on page 5-18.
Inflation - Tire Pressure
Tires need the correct amount of air pressure tooperate effectively.
Notice:Do not let anyone tell you thatunder-inflation or over-inflation is all right. It isnot. If your tires do not have enough air(under-inflation), you can get the following:
•Too much flexing
•Too much heat
•Tire overloading
•Premature or irregular wear
•Poor handling
•Reduced fuel economy
If your tires have too much air (over-inflation),you can get the following:
•Unusual wear
•Poor handling
•Rough ride
•Needless damage from road hazards
