Winter tires
Winter tires can im prove vehic le ha ndling on sno w and
ic e. A t tem peratures belo w 45 °F (7
°C) we rec omm end
cha nging to wint er tires.
In some heavy snow areas, local governments may require true
winte r or "snow" ti res, t hose wi t h very deeply cut tread. These tires
should only be used in pairs and be instal led on all four wheels .
Make sure you purchase snow ti res t hat are the same size and
cons t ruct ion type as the ot her ti res on your vehicle.
If your vehic le is equipped with al l-wheel drive*, this will improve
t raction during w inter dr iving, even with the st andard tires .
However, we strongly recommend that you always equ ip all four
whee ls on you r vehic le wi t h correc tl y fitted winte r ti res or all-season
tires, when winter road conditions are expected. This also improves
th e vehicle's brak ing performance and red uces stoppi ng dista nces.
Summer t ires provide less gr ip on ice and snow.
Winter tires (snow tires) must always be fitted on all four whee ls.
If your veh icle is equipped with a ti re pre ssure monitoring system*,
compatible t ire pressure mon itoring sensors must be installed on
all four winte r tires for the system to function properly ~
page 281.
Ask your aut hori zed Audi dealer or quali fi ed wo rksho p fo r perm itte d
winter tire sizes. Use only radial winter tires.
Winter tires lose thei r effec t iveness when t he tr ead is wo rn down to
a depth of 0 .157 inch (4 mm).
Only drive with winter tires unde r winter conditions. Summer tires
handle bett er w hen there is no snow o r ice on t he roads and th e
temperature is above 45 °F (7 °C).
If you have a fl at tire, see not es on spare whee l ~

Please always remember that w inte r tires may have a lowe r speed
rating than the tires original ly instal led on yo ur vehic le at the time
it was manu factured. Please see~
page 281, "Speed rat ing (letter
code)" for a listing of the speed rating letter codes and the
maximum speed at wh ich t he tir es can be driven .
The speed rating letter code(~
page 2 70) is on the side wa ll of the

page 279.
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off . Never drive faster than the speed permitted for
your specific winter tires . This will cause damage to the tires
leading to an accident and serious personal injury to you and your
passengers.
