UTQGS (Uniform Tire Quality Grading Standards):
A tire information system that provides consumers
with ratings for a tire’s traction, temperature, and
treadwear. Ratings are determined by tire manufacturers
using government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 6-66.
Vehicle Capacity Weight:The number of designated
seating positions multiplied by 150 lbs (68 kg) plus
the rated cargo load. SeeLoading Your Vehicle
on page 5-33.
Vehicle Maximum Load on the Tire:Load on an
individual tire due to curb weight, accessory weight,
occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached to a
vehicle showing the vehicle’s capacity weight and
the original equipment tire size and recommended
ination pressure. See “Tire and Loading Information
Label” underLoading Your Vehicle on page 5-33.Run-Flat Tires
Your vehicle, when new, had run-at tires. There is no
spare tire, no tire changing equipment, and no place
to store a tire in the vehicle. Run-at tires perform
so well without any air that a Tire Pressure Monitor
(TPM) is used to alert you if a tire has lost pressure.
If a tire goes at, you will not need to stop on the side
of the road to change the tire. You can just keep on
driving. The shorter the distance you drive and the
slower the speed, the greater the chance that the tire
will not have to be replaced. If you drive on a deated
run-at tire for 50 miles (80 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that
the tire can be repaired. The tire can operate effectively
with no air pressure for up to 100 miles (160 km) at
speeds up to 55 mph (90 km/h), but the tire would then
have to be replaced. When a tire is lled with air, it
provides a cushion between the road and the wheel.
Because you will not have this cushion when driving on
a deated tire, try to avoid potholes that could damage
your wheel and require replacement of it.

If a Tire Goes Flat
It is unusual for a tire to “blow out” while you are
driving, especially if you maintain your tires properly.
If air goes out of a tire, it is much more likely to leak
out slowly. SeeTires on page 6-50for additional
information.
Your vehicle, when new, had run-at tires. This type
of tire can operate effectively with no air pressure,
so you will not need to stop on the side of the road
to change a at tire. You can just keep on driving.
The shorter the distance you drive and the slower the
speed, the greater the chance that the run-at tire
will not have to be replaced. Run-at tires perform
so well without any air that a Tire Pressure Monitor
(TPM) is used to alert you if a tire has lost pressure.
SeeRun-Flat Tires on page 6-56andTire Pressure
Monitor System on page 6-59.{CAUTION:
When the TIRE FLAT MAX SPD 55, REDUCED
HNDLG message is displayed on the Driver
Information Center, your vehicle’s handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could
lose control of your vehicle. You or others
could be injured. Don’t drive over 55 mph
(90 km/h) when the TIRE FLAT MAX SPD 55,
REDUCED HNDLG message is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
If the TPM system detects a tire pressure below
5 psi (34 kPa), the TIRE FLAT MAX SPD 55, REDUCED
HNDLG warning message is displayed on the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 3-64andDIC Warnings and Messages
on page 3-67for information and details about the
DIC operation and displays.
