General notes With
MOExt ended tires(tires withrunflatchar-

or more tires.Theaffected tiremust notshow

You canrecogniz eaMOExt ended tirebythe
MOExt ended marking whichappears onthe

MOExt ended tiresmaybeused onlyinconj unc-

system (Canada only)ortire pressure monitor
(USA only).
If apressur eloss warning message appears
in the multifu nctiondisplay:
R observe theinstruct ionsinthe display mes-
sages (Ypage 213).
R check thetire fordamage
R ifdriving on,observe thefollowing notes
The driving distance possibleinrun-flat modeis
approximately 50miles (80km) when thevehi-
cle ispartially laden.Whenthevehicle isfully
laden itis approximately 19miles (30km).
In addition tothe vehicle load,thedriving dis-
tance possible depends upon:
R vehicle speed
R road condition
R outside temperature
The driving distance possibleinrun-flat mode
may bereduced byextrem edriving condition s
or maneuvers, oritcan beincreased througha
moderate styleofdriving. The
driving distance possibleinrun-flat modeis
counted fromthemoment thetire pressure loss
warning appears inthe multifunction display.
You must notexceed amaximum speedof
50 mph (80km/h).
When replacing oneorall tires, please observe
the following specifications foryour vehicle's
tires:
R size
R type and
R the "MOExt ended" marking
If atire has gone flatand cannot bereplaced
with aMOExt ended tire,astandard tiremay be
used asatemporary measure.Makesurethat
you usetheproper sizeandtype (summer or
winter tire).
Vehicles equippedwith MOExt ended tiresare
not equipp edwith aTIREFIT kitatthe factory. It
is therefore recommen dedthat youadditionally
equip yourvehicle withaTIREFIT kitifyou mount
tires thatdonot feature run-flat properties, e.g.

TireQuality Grading Standards areU.S.
governmen tspecifications. Theirpurpose isto
provide driverswithuniform reliableinformation
on tire performance data.Tiremanufacturers
have tograde tiresusing threeperformance fac-
tors: 0043tread weargrade, 0044tract iongrade and
0087 temperature grade.Theseregulations donot
apply toCanada. Nevertheless, alltires soldin
North America areprovided withthecorre-
sponding qualitygrading markings onthe side-
wall ofthe tire.
Quality gradescanbefound, whereapplicab le,
on the tire sidewal lbetween treadshoulder and
maximum sectionwidth. Example:
R Tread weargrade: 200
R Tra ction grade: AA
R Temper aturegrade: A
All passenger cartires must confor mto the stat-
utory safety requirements inaddition tothese
grades.
i The
actual values fortires arevehicle-spe-

Tread wear The

under controlled condition son aspecified U.S.
governmen tcourse. Forexample, atire graded

on the governmen tcourse asatire graded 100.
The relative performance oftires depends upon
the actual condition sof their use,however, and
may depart significantly fromthenorm dueto
variations indriving habits, service practices
and differences inroad characterist icsand cli-

The tract iongrade assigned tothis tireis
based onstraight- aheadbraking traction
tests, anddoes notinclude acceleration, cor-
nering, hydropla ning,orpeak tractionchar-

! Avoid
wheelspin. Thiscanlead todamage to
the drive train.
The tract iongrades –from highest tolowest –
are AA, A,Band C.Those grades represent the
tire's abilityto stop onwet pavement asmeas-
