Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can also be affected.
{WARNING
If different sized wheels are used,
there may not be an acceptable
level of performance and safety
if tires not recommended for
those wheels are selected.
This increases the chance of
a crash and serious injury.
Only use GM specific wheel
and tire systems developed
for the vehicle, and have them
properly installed by a GM
certified technician.
See Buying New Tires on
page 10‑64 andAccessories
and Modifications on page 10‑3
for additional information.
Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires
by treadwear, traction, and
temperature performance.
This applies only to vehicles
sold in the United States.

{WARNING
Changing a tire can be
dangerous. The vehicle can
slip off the jack and roll over
or fall causing injury or death.
Find a level place to change the
tire. To help prevent the vehicle
from moving:1. Set the parking brake firmly.
2. Put an automatic transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
(Continued)
WARNING (Continued)
3. Turn off the engine and donot restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks on both sides of the tire at the
opposite corner of the tire
being changed.
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. To use the jacking
equipment to change a spare
tire safely, follow the instructions
below. Then see Tire Changing on
page 10‑79. To use the tire sealant
and compressor kit, see Tire
Sealant and Compressor Kit on
page 10‑72. When the vehicle has a flat tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).

B. Flat Tire
The following information explains
how to repair or change a tire.

10-74 Vehicle Care
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑4.
See If a Tire Goes Flat on
page 10‑70 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑79.
2. Unwrap the sealant/air hose (F) and the power plug (G).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (F)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (G) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑7.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Turn the selector switch (B) clockwise to the Sealant + Air
position. 9. Press the on/off (A) button
to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (D) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (D). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54.

Black plate (75,1)Buick LaCrosse Owner Manual - 2011
Vehicle Care 10-75
The pressure gauge (D) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate pressure
reading. The compressor may
be turned on/off until the
correct pressure is reached.
Notice: If the recommended
pressure cannot be reached
after approximately 25 minutes,
the vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot inflate
the tire. Remove the power plug
from the accessory power outlet
and unscrew the inflating hose
from the tire valve. See Roadside
Assistance Program (U.S.
and Canada) on page 13‑8 or
Roadside Assistance Program
(Mexico) on page 13‑10. 11. Press the on/off button (A)
to turn the tire sealant and
compressor kit off.
The tire is not sealed and
will continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire;
therefore, Steps 12 through 18
must be done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor
kit as it could be warm after
usage.
12. Unplug the power plug (G) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to remove
it from the tire valve stem.
14. Replace the tire valve stem cap. 15. Return the sealant/air hose (F)
and the power plug (G) back in
their original locations.
16. If the flat tire was able to
inflate to the recommended
inflation pressure, remove the
maximum speed label from the
sealant canister and place it
in a highly visible location.
Do not exceed the speed on
this label until the damaged
tire is repaired or replaced.
17. Return the equipment to its original storage location in the
vehicle.
18. Immediately drive the vehicle 8 km (5 mi) to distribute the
sealant in the tire.

safety warnings.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑79.
2. Unwrap the air only hose (E) and the power plug (G).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the tire valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the air only hose (E) onto the tire valve stem by turning it
clockwise until it is tight. 6. Plug the power plug (G) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑7.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Turn the selector switch (B) counterclockwise to the Air
Only position.
9. Press the on/off (A) button to turn the compressor on.
The compressor will inflate the
tire with air only. 10. Inflate the tire to the
recommended inflation
pressure using the pressure
gauge (D). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54.
The pressure gauge (D) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor
off to get an accurate reading.
The compressor may be turned
on/off until the correct pressure
is reached. If the tire is inflated
higher than the recommended
pressure, press the pressure
relief button (C), if equipped,
until the proper pressure
reading is reached. This option
is only functional when using
the air only hose (E).
