Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month~
page 319.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Maintenance and Warranty Booklet.
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals.
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro®l .
• Please rotate tires as shown ~
page 323, fig. 243.
• Extra care must be taken when rotating direction -specific tires
~ page 344.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause excessive tire wear, impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size, construction and tread type. For details see~
page 264.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

& WARNING !continued)
• Never start or run the engine while the vehicle is supported by
the jack.
• If you must work under the vehicle, always use safety stands
specifically designed for this purpose.
• Never use the hexagonal socket in the handle of the screw­
driver to loosen or tighten the wheel bolts .
• Always make sure the spare tire and even a flat tire are secured
in place and not loose , otherwise they could fly forward , causing
personal injury to passengers in the vehicle in an accident or
sudden maneuver. •

After you have loosened all wheel bolts and raised the
vehicle off the ground, remove and replace the wheel as
follows:
Removing the wheel
- Use the hexagonal socket in the screwdriver handle to
completely remove the topmost wheel bolt and set it
aside on a clean surface => fig. 254. - Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt hole=> fig. 255.
- Then remove the other wheel bolts as described above.

remaining wheel bolt slightly like the rest.
- Turn the jack handle counter-clockwise to lower the
vehicle until the jack is fully released .
- Use the wheel bolt wrench to tighten all wheel bolts
firmly => page 341. Tighten them crosswise, from one
bolt to the (approximately) opposite one, to keep the
wheel centered .
[ i] Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bolts.
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way~
