Winter tires

6. If your vehicle will be towing a

trailer, load from your trailer

will be transferred to your ve-

hicle. Consult this manual to

determine how this reduces

the available cargo and lug-

gage load capacity of your ve-

hicle.

Winter tires significantly improve the vehicle's

handling when driving in winter conditions. Be-

cause of their construction (width, compound,

tread pattern), summer tires provide less traction

on ice and snow.

►

Use winter tires on all four wheels.

►

Only use winter tires that are approved for your

vehicle.

►

Please note that the maximum permitted

speed may be lower with winter tires ð

General information on page 268. An author-

ized Audi dealer or authorized Audi Service Fa-

cility can inform you about the maximum per-

mitted speed for your tires.

►

Check the tire sidewall

(ðpage 269, fig. 175) to deter-

mine the designated load rating

for a specific tire.

►

Check the tire pressure after installing a wheel

ðpage 279.

The effectiveness of winter tires is reduced great-

ly when the tread is worn down to a depth of

0.16 in (4 mm). The characteristics of winter

tires also decrease greatly as the tire ages, re-

gardless of the remaining tread.

Wheel bolts and rims

Wheel bolts

Wheel bolts must be clean and must loosen and

tighten easily.

For the sake of the environment

Rims

Reinstall summer tires at the appropriate

time, because they provide better handling

when roads are free of snow and ice. Summer

tires cause less road noise, tire wear, and fuel

consumption.

Rims with a bolted rim ring* or with bolted wheel

covers* consist of multiple pieces. These compo-

nents were bolted together using special bolts

and a special procedure. You must not repair or

disassemble them ð

Tips

WARNING

You can also use all season tires instead of

winter tires. Please note that in some coun-

tries where winter tires are required, only

winter tires with the  symbol may be per-

mitted.

Wheel bolts that are tightened or repaired in-

correctly can become loose and result in loss

of vehicle control, which increases the risk of

an accident. For the correct tightening specifi-

cation, see ðpage 302, Finishing.

– Always keep the wheel bolts and the threads

in the wheel hub clean and free of grease.

– Only use wheel bolts that fit the rim.

Snow chains

Snow chains improve both driving and braking in

winter road conditions.

– Always have damaged rims repaired by an

authorized Audi dealer or authorized Audi

Service Facility. Never repair or disassemble

►

Only install snow chains on the rear wheels.

Wheels

►

Check and correct the seating of the snow

chains after driving a few feet, if necessary. Fol-

low the instructions from the manufacturer.

Note the maximum speed of 30 mph

may reduce the level of comfort and increase

road noise when driving on roads in poor condi-

tion.

Low-profile tires can become damaged more

quickly than standard tires when driving over

large bumps, potholes, manhole covers, and

curbs. Therefore, it is particularly important to

maintain the correct tire pressure ðpage 279.

(50 km/h). Observe local regulations.

Use of snow chains is only permitted with certain

rim/tire combinations due to technical reasons.

Check with an authorized Audi dealer or author-

ized Audi Service Facility to see if you may use

snow chains.

To reduce the risk of damage to the tires and

rims, drive very carefully on poor roads.

Use fine-mesh snow chains. They must not add

more than 0.53 inch (13.5 mm) in height, includ-

ing the chain lock.

Check your wheels regularly every 2,000 miles

(3,000 km) for damage. For example, check for

bulges/cracks on the tires or deformations/

cracks on the rims.

You must remove the snow chains on roads with-

out snow. Otherwise, you could impair driving

ability and damage the tires.

After a heavy impact or damage, have the tires

and rims inspected or replaced immediately by

an authorized Audi dealer or authorized Audi

Service Facility.

WARNING

Using incorrect snow chains or installing snow

chains incorrectly can result in loss of vehicle

control, which increases the risk of an acci-

dent.

Low-profile tires can wear out faster than stand-

ard tires.

Uniform tire quality grading

Note

– Tread wear

– Snow chains can damage the rims and

wheel covers* if the chains come into direct

contact with them. Remove the wheel cov-

ers* first. Use coated snow chains.

– Traction AA A B C

– Temperature A B C

Quality grades can be found where applicable on

the tire side wall between tread shoulder and

maximum section width ðpage 269, fig. 175.

– Do not install and use snow chains if there is

a malfunction in the air suspension*, be-

cause the vehicle height will be very low. If

you drive with snow chains anyway, the

wheel housings and other vehicle compo-

nents can be severely damaged.

For example: Tread wear 200, Traction AA, Tem-

perature A.

All passenger car tires must conform to Federal

Safety Requirements in addition to these grades.

Tips

Tread wear

When using snow chains, it may be advisable

to limit the ESC ðpage 121.

The tread wear grade is a comparative rating

based on the wear rate of the tire when tested

under controlled conditions on a specified gov-

ernment test course.

Low-profile tires

Applies to: vehicles with low-profile tires

For example, a tire graded 150 would wear one

and one half (1 1/2) times as well on the govern-

ment course as a tire graded 100.

Compared to other tire/rim combinations, low-

profile tires offer a wider tread surface and a

larger rim diameter with shorter tire sidewalls.

This results in an agile driving feel. However, it

The relative performance of tires depends upon

the actual conditions of their use, however, and

may depart significantly from the norm due to

variations in driving habits, service practices and

differences in road characteristics and climate.

WARNING

Temperature grades apply to tires that are

properly inflated and not over or underinflat-

ed.

Traction

The traction grades, from highest to lowest, are

AA, A, B and C. Those grades represent the tire's

ability to stop on wet pavement as measured un-

der controlled conditions on specified govern-

ment test surfaces of asphalt and concrete. A tire

marked C may have poor traction performance

Tire pressure monitoring

system

 General notes

Each tire, including the spare (if provided),

should be checked monthly when cold and inflat-

ed to the inflation pressure recommended by the

vehicle manufacturer on the vehicle placard or

tire inflation pressure label. (If your vehicle has

tires of a different size than the size indicated on

the vehicle placard or tire inflation pressure la-

bel, you should determine the proper tire infla-

tion pressure for those tires).

Temperature

The temperature grades are A (the highest), B,

and C, representing the tire's resistance to the

generation of heat and its ability to dissipate

heat when tested under controlled conditions on

a specified indoor laboratory test wheel.

Sustained high temperature can cause the mate-

rial of the tire to degenerate and reduce tire life,

and excessive temperature can lead to sudden

As an added safety feature, your vehicle has been

equipped with a tire pressure monitoring system

(TPMS) that illuminates a low tire pressure tell-

tale when one or more of your tires is significant-

ly under-inflated. Accordingly, when the low tire

pressure telltale illuminates, you should stop and

check your tires as soon as possible, and inflate

them to the proper pressure. Driving on a signifi-

cantly under-inflated tire causes the tire to over-

heat and can lead to tire failure. Under-inflation

also reduces fuel efficiency and tire tread life,

and may affect the vehicle's handling and stop-

ping ability.

tire failure ð

The grade C corresponds to a level of perform-

ance which all passenger car tires must meet un-

der the Federal Motor Vehicle Safety Standard

No. 109. Grades B and A represent higher levels

of performance on the laboratory test wheel than

the minimum required by law.

WARNING

The traction grade assigned to this tire is

based on straight-ahead braking traction

tests, and does not include acceleration, cor-

nering, hydroplaning or peak traction charac-

teristics.

Please note that the TPMS is not a substitute for

proper tire maintenance, and it is the driver's re-

sponsibility to maintain correct tire pressure,

even if under-inflation has not reached the level

to trigger illumination of the TPMS low tire pres-

sure telltale.

WARNING

The temperature grade for this tire is estab-

lished for a tire that is properly inflated and

not overloaded. Excessive speed, underinfla-

tion, or excessive loading, either separately or

in combination, can cause heat buildup and

possible tire failure.

Your vehicle has also been equipped with a TPMS

malfunction indicator to indicate when the sys-

tem is not operating properly. The TPMS mal-

function indicator is combined with the low tire

pressure telltale. When the system detects a

malfunction, the telltale will flash for approxi-

mately one minute and then remain continuously

illuminated. This sequence will continue upon
