wheel BUICK RANDEZVOUS 2005 Workshop Manual

Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specied indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
If you notice unusual tire wear or your vehicle pulling
one way or the other, the alignment may need to
be reset. If you notice your vehicle vibrating when driving
on a smooth road, your wheels may need to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
5-68

If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts
for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-72for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
5-69

Tire Chains
{CAUTION:
Don’t use tire chains. There’s not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash. Use another type of traction device
only if its manufacturer recommends it for use
on your vehicle and tire size combination and
road conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it’s contacting your vehicle, and don’t
spin your wheels. If you do nd traction
devices that will t, install them on the front
tires for front-wheel-drive vehicles. If your
vehicle has all-wheel drive, install traction
devices on either the front tires or all four
tires, but never on the rear tires only.
Accessory Inator
Your vehicle may have an accessory inator. With it, you
can inate things like air mattresses and basketballs, and
you can also use it to bring your tires up to the proper
pressure.
The accessory inator is located in the rear
compartment on the driver’s side. To remove the cover,
pull the tab on the cover and pull it off.
This is the symbol on the
accessory inator switch.
There may be an accessory inator kit stored in the
glove box. It includes a 20-foot (6 m) hose with an air
pressure gage and nozzle adapters.

If a Tire Goes Flat
It’s unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use your
jacking equipment to change a at tire safely.
Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers.
5-72

{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.When you have a at tire, use the following example as a
guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use
the jack and change a tire.

4. Tilt the retainer and slip it through the wheel
opening to remove the spare tire from the cable.
5. Turn the wrench clockwise to raise the cable back
up after removing the spare tire.
Do not store a full-size or a at road tire under the
vehicle. SeeStoring a Flat or Spare Tire and
Tools on page 5-88.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-80.If the spare tire will not lower, the secondary latch may
be engaged causing the tire not to lower.
Do the following to check the cable:
1. Check under the vehicle to see if the cable is visible.
2. If it is not visible, seeSecondary Latch System on
page 5-84.
If it is visible, rst try to tighten the cable by turning
the folding wrench clockwise until you hear two
clicks or feel it skip twice. You cannot over-tighten
the cable.

1. Open the storage compartment door of the
convenience center that is nearest the liftgate and
remove the cap on the bottom of the storage
compartment.
2. Flip the cut out carpet that is located through the
hole of the storage compartment.
3. Attach the folding wrench into the hoist shaft.
4. Turn the folding wrench counterclockwise to lower
the spare tire to the ground. Continue turning the
wrench until the spare tire can be pulled out
from under the vehicle.
5. Tilt the retainer and slip it through the wheel
opening to remove the spare tire from the cable.
6. Turn the wrench clockwise to raise the cable back
up after removing the spare tire.
Do not store a full-size or a at road tire under the
vehicle. SeeStoring a Flat or Spare Tire and
Tools on page 5-88.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-80.

Removing the Flat Tire and
Installing the Spare Tire
1. If there is a wheel cover, loosen the plastic nut
caps with the wheel wrench. They will not come
off. Then, using the at end of the wheel wrench,
pry along the edge of the cover until it comes off.
Be careful; the edges may be sharp. Do not
try to remove the cover with your bare hands.
If your vehicle has aluminum wheels, remove the
wheel nut caps using the wheel wrench.
2. Loosen the wheel
nuts — but do not
remove them — using
the folding wrench.
Turn the handle about
180 degrees, then
ip the handle back to
the starting position.
This avoids taking
the wrench off the lug
nut for each turn.
For wheels with a wheel lock key, use the wheel
lock key between the lock nut and folding wrench.
The key is supplied in the front passenger door
pocket.Notice:If your vehicle has wheel locks and you
use an impact wrench to remove the wheel nuts,
you could damage the lock nut or wheel lock key.
Do not use an impact wrench to remove the
wheel nuts if your vehicle has wheel locks.
3. Locate the notch (A is
3.0 inches (7.5 cm)
from the front tire or B
is 5.5 inches (14.0
cm) from the rear tire).
The notch is located
near each wheel in the
vehicle’s body.
Notice:If you use a jack to raise the vehicle
without positioning it correctly, you could damage
your vehicle. When raising your vehicle on a
jack, avoid contact with the rear axle control arms.
Do not raise the vehicle yet. Put the compact spare
tire near you.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only
by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.4. Attach the folding
wrench to the jack, and
turn the wrench
clockwise to raise the
jack head 3 inches
(7.6 cm).
5. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far
enough off the ground so that there is enough room
for the spare tire to t under the wheel well.
6. Remove all the wheel nuts and take off the at tire.
5-81

{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
