vehicle handling and can lead to a loss of
control.
- If the replacement tire is not the same as
the tires that are mounted on the vehicle
- for example with winter tires - only use
the replacement t ire for a short period of
t ime and dr ive with extra care . Refit the
normal road wheel as soon as safely pos­
sible.
- Never drive faste r than the maximum
speed for which the tires on your veh icle
are rated because ti res that are driven
faster than their rated speed can fail
sudden ly.
- Overloading t ires cause heat build-up,
sudden tire failure, including a blowo ut
and sudden deflation and loss of control.
- T emperature grades app ly to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not a lways
possible to use wheels from othe r
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­ hicle whee ls, make sure that the air f low
to the brakes is not blocked . Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision .
- Run flat tires may only be used on
vehicles that were equipped w ith them
at the factory . The vehicle must have a
chassis des igned for run flat t ires and a
factory-installed t ire pressure monitor­
ing system* that indicates a loss of ti re
pressure. Incorrec t use of run flat tires
can lead to vehicle damage or accidents .
Check with an authorized Audi dea ler or
tire spec ialist to see if your vehicle can be
equipped with run flat tires . If run flat
tires are used, they must be installed on
all four wheels. M ixing tire types is not
permitted .
(D Note
-For technica l reasons, it is not genera lly
possible to use the wheel r ims from oth- er vehicles.
This can hold true for wheels
of the same vehicle type.
- If a rep lacement tire is different from
the tires that you have mounted on your
vehicle (for example winter tires or wide profile tires), then use the rep lacement
tire for a short period of time only and dr ive with extra care. Replace the flat tire
w ith the tire match ing the others on your
vehicle as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged .

Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Tempe rature ABC
Quality grades can be found where applicab le
on the t ire s ide wall between tread shou ld er
and maximum section width c> page 233,
fig. 189 .
For exampl e: Tread wear 200 , Traction AA,
Temperature A.
All passenger car t ires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
T he tread wear grade is a comparative rating
based on the wear rate of the t ire when tested
u nder controlled conditions on a specified
government test course .
For example, a tire graded 1S0 would wear
one and one ha lf (11/2) times as well on the
gover nment course as a t ire graded 100 .
The relative performance of tires depends upon the actual conditions of their use, how­
ever, and may depa rt s ignificantly from the
norm due to va ria tions in d riving hab its, serv­
ice practices and differences in road character-
istics and climate.
