CHEVROLET 2010 HHR - Manual (Page 354)

Cold Tire Pressure : The amount of air pressure in
a tire, measured in pounds per square inch (psi) or
kilopascals (kPa) before a tire has built up heat
from driving. See Inflation - Tire Pressure on
page 6-62.
Curb Weight : The weight of a motor vehicle with
standard and optional equipment including the
maximum capacity of fuel, oil, and coolant,
but without passengers and cargo.
DOT Markings : A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identification Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.
GVWR : Gross Vehicle Weight Rating. See
Loading the Vehicle on page 5-24.
GAWR FRT : Gross Axle Weight Rating for the
front axle. See Loading the Vehicle on page 5-24.
GAWR RR : Gross Axle Weight Rating for the
rear axle. See Loading the Vehicle on page 5-24.
Intended Outboard Sidewall : The side of an
asymmetrical tire, that must always face outward
when mounted on a vehicle.
Kilopascal (kPa) : The metric unit for air pressure.
Light Truck (LT-Metric) Tire : A tire used on
light duty trucks and some multipurpose passenger
vehicles.
Load Index : An assigned number ranging from
1 to 279 that corresponds to the load carrying
capacity of a tire.
Maximum Inflation Pressure : The maximum air
pressure to which a cold tire can be inflated.
The maximum air pressure is molded onto the
sidewall.
Maximum Load Rating : The load rating for a tire
at the maximum permissible inflation pressure
for that tire.
Maximum Loaded Vehicle Weight : The sum of
curb weight, accessory weight, vehicle capacity
weight, and production options weight.
Normal Occupant Weight : The number of
occupants a vehicle is designed to seat multiplied
by 150 lbs (68 kg). See Loading the Vehicle on
page 5-24.
