Tr eadwear The
treadwear gradeisac omparative rating
based onthe wear rateofthe tire when tested
under controlled conditionsonaspecified U.S.
governm entcourse. Forexample, atire graded
150 would wearoneandone-half timesaswell
on the governm enttest track asatire graded

The relative performan ceoftires depends
upon theactual conditionsoftheir use,how-
ever, andmay depart significant lyfrom the
norm duetovariations indriving habits, ser-

The tract iongrade assigned tothis tireis
based onstraight -aheadbraking traction
test s,and does notinclude acceleration ,
corn ering, hydroplaning, orpeak traction
charact eristics.
! Avoid
wheelspin. Thiscanlead todamage
to the drive train.
The tract iongrades –from highest tolowest –
are AA, A,Ba ndC.Those grades represent the
tire's ability tostop onwet pavement asmeas-
ured under controlled conditionsonspecified

The safe speed onaw et,snow covered oricy

You should payspecial attentiontoroad con-
ditions whentemperat uresarearound freezing
point.
Mercedes- Benzrecomm endsaminimum tread
depth of00CF in(4 mm) onallfour winter tires.
Observe thelegally required minimum tire
tread depth (Ypage 269). Winter tirescan
reduce thebraking distance onsnow-c overed
surfaces incomparison withsummer tires.The
braking distance isstill much further thanon surfaces
thatarenot icyorcovered withsnow.
Take appropriate carewhen driving.

The temperat uregrade forthis tireisestab-
lished foratire that isproperly inflatedand
not overloaded. Excessive speed, underinfla-
tion, orexcessiv eloading, eitherseparately
or incombinat ion,cancause excessiv eheat
build-up andpossible tirefailure.
The temperat uregrades areA(the highest), B,
and C,represent ingthe tire's resistanc etot he
generation ofheat anditsability todissipate
heat when testedunder controlled conditions
on aspecified indoorlaboratory testwheel.
Sustained hightemperat urecan cause the
material ofthe tire todegenerate andreduce
tire life, and excessiv etemperat urecan lead to
sudden tirefailure. Thegrade Ccorrespon ds
