2014 AUDI R8 SPYDER winter tires

204 Tire s and wheel s
This also improves the vehicle's braking
performance and reduces stopping distances .
Summer tires provide less g rip 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 your authorized Aud i dea le r 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
d itions. 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 than the t ires origi­
na lly installed on your vehicle at the t ime it
was manufactured. Please see~
page 200,
Speed rating (letter code)
for a List ing of the
speed rat ing letter codes and the maximum
speed at wh ic h t he t ires ca n be dr iven .
The speed rating letter code
( ~ page 192) is
on the s ide wall of the tire~
page 199 .
A WARNING
Winter tires have maximum s peed limits
th at may be lowe r than you r vehi cle's m ax­
im um speed. Always know the maxim um
speed befo re d riving off . Never d rive faster
than the speed permitted for your specific
w inte r tires. This will cause damage to the
tires leading to an accident and serious
personal in jury to you and yo ur passen­
gers.
A WARNING
Dr iv ing faster than the maximum speed
for which the w inter t ires on your vehicle
-
were designed can cause t ire fail ure in­
cluding a blowout and sudden deflation,
l oss of contro l, crashes and ser ious per­
sona l injuries. Have worn o r damaged tires
r eplaced immediately .
- W inter tires have maximum speed rating
that may be lower than yo ur vehicle 's
maximum speed.
- Never d rive faster than the speed for
which the w in ter or othe r tires installed
on yo ur vehicle a re rated .
A WARNING
-Always ad just your dr iv ing to the road and
traffic condit ions . Never let the good ac­
ce ler ation o f the w in ter t ires and a ll-wheel
d rive tempt yo u into t aking extra risks. Al­
ways remember:
- W hen braking, an all-wheel drive veh icle
handles in the same way as a front drive
vehicle .
- D rive c arefully and redu ce your spee d on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
@ For the sake of the environment
Use summer tires when weather condi­
tions permi t. T hey are qu iete r, do no t wear
as quickly and reduce fuel consumpt ion .
Snow chains
Snow chains may be fitted only to the rear
whee ls, and on ly to certain tire sizes . Ask your
authori zed Aud i dea ler on which tire si zes
snow chains ca n be used .
The snow chains must have low -profi le links
and must not be th icker than 0.53 inch
(13 .5 mm), includ ing the lock.
Remove whee l center covers before putt ing
snow c hains on your vehicle
~ CD . For safety
reasons cover caps must then be f itted over
the wheel bolts. These are available from au­
thorized Audi dea le rs.

206 Tires and wheels
and handling under a variety of driving condi­
tions. Ask your authorized Audi dea ler 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 o f 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 195, Checking tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio t ires can be damaged more
ea5i ly by impact with potho le5, curb5, gullie5
or ridges on the road, particularly if the tire is
underinflated .
In order to minimize the occur rence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Chec k your tire pressure every
2.000 miles (3.000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h ro ugh or over such obstacles can damage
yo ur tir es. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tir es or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ir e as soon as possible.
- Inspect your t ires 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, wh ich 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 h igh performance
t ir es or iginally installed on your vehicle are in­
tended for maximum dry and wet road per­
fo rmance and handling . They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those circumstances, you
sho uld equ ip your vehicle with all-season or
winter tires, which offer better traction unde r
those conditions. We suggest you use the rec ­
ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to~
page 203 for more de tailed infor­
mation regarding winter tires.
Tire pressure
monitoring system
General notes
Each tire, including the spare (if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation pressure recommended
by the veh icle manufact urer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in ­
flat io n pressure label, you should dete rmine
the proper t ire inflation pressure for those
t i r es.).
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low tire
pressure telltale when one or more of you r
t ir es is significantly under-inflated. According -
ly, when the low tire pressure telltale ..,.
