Tire specifications
Knowledge of tire specifications makes it eas­
i er to choose the correct tires. Radial tires
have the tire specifications marked on the
sidewall, for example :
P255 / 35 R19 96V XL
This contains the follow ing information:
P Indicates the tire is for passenger cars
(where applicable)
255 Nominal tire width in mm of the tire
from sidewa ll edge to sidewall edge. In
general, the larger the number, the wider
the tire
35 Height/width ratio in percent (aspect ra-
tio)
R Tire construction: Radial
19 Rim diameter code (in inches)
96 Load rating code
Y Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF" Indicates
that the tire is a"Reinforced" or an "Extra L oad" tire
M+S (or "M/S") Indicates that the tire has
some mud and snow capability
The t ires could also have the information of
d ir ection of rotation~
page 230.
Tire manufacturing date
The manufacturing date is also indicated on
the tire sidewall (poss ibly only on the
inner
side of the wheel):
"DOT . .. 2213 . .. "means, for examp le, that
the tire was produced in the 22nd week of
2013.
Speed rating (letter code)
The speed rating letter code on the wheels in­
dicates the maximum permissib le road speeds

tires, which possess excellent dr iving charac­
teristics and give your Aud i optimum driving
comfort . An electron ic speed lim iter

U.S. DOT Tire Identification Number (TIN)
and tire manufacture date
T his is the tire's "se rial number". It begins
with the letters "DOT" and indicates that the
tire meets all federa l standards. The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example, the numbers 2213 mean that
the tire was produced in the 22nd week of
2013 . The other numbers are marketing co ­
des that may or may not be used by the tire
manufacturer . T his information is used to con­
tact consumers if a tire defect requ ires a re­
call.
Audi Original tire
Tires with the identification "AO" or "RO" have
been specially matched with your Audi . We
recommend using only these tires because
they meet the highest standards regarding
safety and driving characterist ics w hen used
correct ly . Your authorized Audi dealer will
gladly provide you with more information . ...,

248 Tires and wheels
diagonally. After changing a wheel, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi­
tions. Ask your authorized Audi dealer for more details.
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's size
designation. The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is
regularly checked and maintained. Tire pres­
sures should be checked at least once a
month and always before a long trip
~ page 23 7, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gullies
or ridges on the road, particularly if the tire is
underinflated.
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary. -
Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 miles (3,000
km) for damage and wear. Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, which could eventu­
ally cause tire failure.
If you believe that a
tire may have been damaged, replace the
tire as soon as possible.
- These tires may wear more quickly than oth­
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec­
ommended snow or all-season tires specified
for your vehicle , or their equivalent.
Refer to
~ page 246 for more detailed infor­
mation regarding winter tires.
