Even ifyou have calculated thetotal cargo
carefully, youshould stillmake surethatthe
gross vehicle weightratingandthegross axle
weight ratingarenot exceeded. Detailscanbe
found onthe vehicle identification plateonthe
B-pillar onthe driver's sideofthe vehicle
(Y page 280).
Permissible grossvehicle weight: thegross
weight ofthe vehicle, allpassengers andthe
load must notexceed thepermissible gross
vehicle weight. Gross
AxleWeight Rating (GAWR): themaxi-
mum permissible weightthatcanbecarried by
one axle (front orrear axle).
To ensure thatyour vehicle doesnotexceed
the maximum permissible values(grossvehi-

Overview ofTire Quality Grading
Stand ards Uniform
TireQuality Grading Standards are
U.S. governmen tspecifications. Theirpurpose
is to provide driverswithuniform reliableinfor-
mation ontire performance data.Tiremanu-
facturers havetograde tiresusing threeper-
formanc efactors: 0043tread weargrade, 0044
tract iongrade and0087temperature grade.
These regulations donot apply toCanada.
Nevertheless, alltires soldinNorth America
are provided withthecorrespondin gquality
grading markings onthe sidewal lofthe 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 mtothe
statutory safetyrequirements inaddition to
these grades. 282

alltires withtheM+S marking provide
the driving characteristics ofwinter tires.In
addi tion tothe M+S marking, wintertires
also have the004D snowflake symbolonthe
tire wall.Tires withthismarking fulfillthe

An electronic speedlimiter prevents yourvehi-
cle from exceeding aspeed of130 mph
(210 km/h).
The speed ratingoftires mounted atthe fac-
tory may behigher thanthemaximum speed
that theelectronic speedlimiter permits.
Make surethatyourtires have therequi red
speed rating, e.g.when buying new tires. The
requi redspeed ratingforyou rvehicle canbe
found inthe "tires" section (Ypage 293).
Further information aboutreadi ngtire data
can beobtained fromanyqualifiedspecia list

Load index In
addi tion tothe load -bearing index,load
index 0043may alsobeimprinted onthe side-
wal lofthe tire. Youwillfind this after thelet-
