This also improves the vehicle's braking
performance and reduces stopping distances .
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four wheels.
Compat ible tire pressure mon itoring sensors
must be installed on all four winter tires for
the tire pressure monitor ing system to func-
tion properly ~ page 201 .
Ask you r authorized Audi dealer or qualified
workshop for permitted wint er tire sizes. Use
on ly radia l wi nte r tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0 .157 inch
(4 mm).
Only drive with winter tires under winter con-
ditions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remember that w inter t ires may
have a lower speed rating t han t he t ires origi-
nally installed on your vehicle at the t ime it

speed rat ing letter codes and the maximum
speed at wh ich t he t ires can be dr iven .
The speed rating letter code (~ page 192) is
on the side wall of the tire ~ page 199 .
