balanced
in
the spring, andthose withmud and
snow tiresbefore winter.
Unbalanced wheelsmayaffect carhandling and
tire life.
Only thespecified weightsmaybeused forwheel
balancing. Self-adhesive weightsmustnotcome intocontact
with cleaning agents,sincetheycould dropoff.
A wheel should always bebalanced afteratire re-
pair.
Uneven treadwearindicates wheelimbalance. In
this event, thevehicle shouldbechecked atan au-
thorized Porschedealer.

/!\.
Warning!
If, during ajourney, unevenrunning orvibra-
tions occur thatcould becaused bydamage
to tires orthe car, thespeed mustbere-
duced immediately, butwithout braking
sharply.

Practical Tips,Emergency Service
Removing
andstoring tires

c>
After changing, adjusttirepressure andtorque
wheel boltsdiagonally to94 ftlb (130 Nm).
Please observe thechapter "CHANGING A
WHEEL" onPage 150.

Tires mustalways remain onthe same side
of the vehicle.

When wheels areremoved, thedirection ofrota-
tion andposition ofeach wheel should bemarked.

Example

FR (front right), FL,RRand RL.
Wheels mustalways befitted inaccordance with
their marking.
The preception thattiredurability andperfor-
mance areimmune tothe effects ofstorage and
age isunfounded.
Chemical additives, whichmaketherubber elas-
tic, lose their effectiveness inthe course oftime
and therubber becomes brittleandcracks.

Therefore, thetires should beinspected
from timetotime. Note

Under nocircumstances shouldtiresolder than6
years beused onyour Porsche.
The ageofthe tire can beobtained fromthe"DOT"
code number. If,for example, thelast four num-
bers read 1203, thenthetire was produced inthe
12th week of2003.

c>
Store tiresinacool anddryplace.

ture areoptimized forwet and drydriving
