(A) Temporary Use Only:The compact spare tire or
temporary use tire has a tread life of approximately
3,000 miles (5 000 km) and should not be driven
at speeds over 65 mph (105 km/h). The compact spare
tire is for emergency use when a regular road tire
has lost air and gone at. If your vehicle has a compact
spare tire, seeCompact Spare Tire on page 5-88
andIf a Tire Goes Flat on page 5-77.(B) Tire Ply Material:The type of cord and number of
plies in the sidewall and under the tread.
(C) Tire Identi cation Number (TIN):The letters
and numbers following the DOT (Department of
Transportation) code is the Tire Identi cation Number
(TIN). The TIN shows the manufacturer and plant code,
tire size, and date the tire was manufactured. The TIN
is molded onto both sides of the tire, although only
one side may have the date of manufacture.
(D) Maximum Cold In ation Load Limit:Maximum
load that can be carried and the maximum pressure
needed to support that load.
(E) Tire In ation:The temporary use tire or compact
spare tire should be in ated to 60 psi (420 kPa).
For more information on tire pressure and in ation see
In ation - Tire Pressure on page 5-66.
(F) Tire Size:A combination of letters and numbers
de ne a tire’s width, height, aspect ratio, construction
type and service description. The letter T as the
rst character in the tire size means the tire is for
temporary use only.
(G) TPC Spec (Tire Performance Criteria
Speci cation):Original equipment tires designed
to GM’s speci c tire performance criteria have a
TPC speci cation code molded onto the sidewall.
GM’s TPC speci cations meet or exceed all federal
safety guidelines. Compact Spare Tire Example

Tire Pressure Monitor System
If your vehicle has the tire pressure monitor system,
it can alert you to a large change in the pressure of one
tire. The system “learns” the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 45 and 90 minutes
of driving to learn the tire pressures. This time may
be longer depending on your individual driving habits.
Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is recalibrated.
After the system has learned tire pressures with
properly in ated tires, the LOW TIRE PRESSURE
message will come on if the pressure in one tire
becomes 12 psi (83 kPa) lower than the other
three tires. The tire pressure monitor system won’t
alert you if the pressure in more than one tire is low,
if the system is not properly calibrated, or if the vehicle
is moving faster than 70 mph (110 km/h).
The tire pressure monitor system detects differences
in tire rotation speeds that are caused by changes
in tire pressure. The system can alert you about a
low tire — but it doesn’t replace normal tire
maintenance. SeeTires on page 5-60.When the LOW TIRE PRESSURE message comes on,
you should stop as soon as you can and check all
your tires for damage. (If a tire is at, seeIf a Tire Goes
Flat on page 5-77.) Also check the tire pressure in all
four tires as soon as you can. SeeIn ation - Tire
Pressure on page 5-66.
The LOW TIRE PRESSURE message will also be
displayed (while the ignition is on) until you reset
(calibrate) the system.
Don’t reset the tire pressure monitor system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the system will not work properly and may not alert you
when a tire is low.
Any time you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire pressure monitor
system. You’ll also need to reset the system whenever
you buy new tires and whenever the vehicle’s battery
has been disconnected.
