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 6‑60
.
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.

.
GAWR FRT
: Gross Axle Weight Rating for the
front axle. See Loading the Vehicle
on page 5‑23
.
GAWR RR
: Gross Axle Weight Rating for the
rear axle. See Loading the Vehicle

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
