Depen din g on th e re spective integration type,
th is includes, fo r ex ample:R
ge neral ve hicle informationR
position data
This enables th e use of selected smartphone
Apps, e.g. navigation or music playbac k. There is
no fur th er interaction between th e smartphone
and th e ve hicle; in particular, ve hicle data is not
directly accessible. The type of fur th er data pro‐
cessing is de te rm ined by th e pr ov ider of th e App
used. The re spective App and yo ur smartphone's
operating sy st em de te rm ine whe th er ch anges
can be made to th e settings and which settings
can be ch anged. Service pr ov iders
Wire less network connection
If yo ur ve hicle has a wireless network connec‐
tion, it enables data to be exc hanged between
yo ur ve hicle and additional sy st ems. The wire‐
less network connection is enabled via th e ve hi‐
cle's transmission and re ception unit or via con‐
nected mobile end devices (e.g. sma rt phones).
Online functions can be used via th e wireless
network connection. This includes online serv‐
ices and applications/Apps pr ov ided by th e
manufacturer or ot her pr ov iders.
Manu fa ctu re r's se rv ices
The manufacturer describes th e re spective func‐
tions and cor re sponding legal data pr ot ection
information when suitable fo r th e manufacturer's
online services. Pe rs onal data may be used fo r
th e pr ov ision of online services. Data is
exc hanged via a secure connection, e.g. to th e
manufacturer's designated IT sy st ems. Pe rs onal
data is collected, processed and used via th e
pr ov ision of services ex clusively on th e basis of
legal permissions or with prior consent. The services and functions (sometimes subject
to a fe e) can usually be activated or deactivated.
In some cases, th is also applies to th e entire
ve hicle's data connection. This exc ludes, in par‐
ticular, legally prescribed functions and services.
Third pa rt y services
If it is possible to use online services from ot her
pr ov iders, th ese services are subject to th e data
pr ot ection and te rm s of use of th e re sponsible

th e con te nt exc hanged.
Please enquire, th erefore, about th e type, scope
and purpose of th e collection and use of per‐
sonal data as part of th ird party services from
th eir re spective pr ov ider.
COMAND/mbrace
If th e ve hicle is equipped with CO MAND or
mbrace, additional data about th e ve hicle's oper‐
ation, th e use of th e ve hicle in cer ta in situations,
and th e location of th e ve hicle may be compiled

General no te s

Preceding letter 1 :R
Wi th out: passenger ve hicle tires according to
European manufactu ri ng st andards.R
"P": passenger ve hicle tires according to US
manufacturing st andards.R
"LT": light truck tires according to US manu‐
fa cturing st andards.R
"T": compact emer ge ncy spa re wheels with
high tire pressure th at are on ly designe d fo r
te mp orary use in an emer ge ncy.
Aspect ra tio 3 :
Ra tio between tire height and tire width in per‐
cent (ti re height divided by tire width).
Tire code 4 (ti re type):R
"R" ra dial tireR
"D": bias ply tire R
"B": bias belted tires R
"ZR": ra dial tire with a maximum speed abo ve
14 9 mp h (240 km/h) (optional) Rim diame te r 5 :
The diam et er of th e bead seat (not th e diame te r
of th e ri m fl ange). The ri m diame te r is specified
in inches (in).
Load-bearing index 6 :
Numerical code th at specifies th e maximum
load-bearing capacity of a tire (e.g. "91" cor re ‐
sponds to 13 56 lbs (6 15 kg )).
The load-bearing capacity of th e tire must be at
least half th e permissible axle load of yo ur ve hi‐
cle. Do not ove rl oad th e tires by exc eeding th e
specified load limit.

Load ind ex
Speed ra ting 7 :
Specifies th e appr ove d maximum speed of th e
tire.

th ese are ins ta lled on th e ve hicle, but does not
include passengers or luggage.
Maximum tire load: th e maximum tire load is
th e maximum permissible we ight in kilog ra ms or
lbs fo r whi ch a tire is appr ove d.
Maximum permissible tire pressure: maxi‐
mum permissible tire pressure fo r one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated by dividing th e maxi‐
mum axle load of one axle by two.
PSI (pounds per square in ch ): st andard unit of
measurement fo r tire pressu re .
Aspect ra tio: ra tio between tire height and tire
width in pe rc ent.
Ti re pressure: pressure inside th e tire applying
an outward fo rc e to eve ry square inch of th e tire.
The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be cor re cted when
th e tires are cold.
Cold tire pressure: th e tires are cold when th e
ve hicle has been par ke d fo r at lea st 3 hou rs without direct sunlight on th e tires or th e ve hicle
has been driven fo r less th an 1 mile (1.6 km).
Ti re contact sur fa ce: th e part of th e tire th at
comes into con ta ct wi th th e ro ad.
Ti re bead: th e purpose of th e tire bead is to
ensure th at th e tire sits securely on th e wheel
ri m. There are se ve ra l wire cores in th e tire bead
to pr eve nt th e t ir
e from ch anging length on th e
wheel ri m.
Side wa ll: th e part of th e tire between th e tread
and th e tire bead.
We ight of optional equipment: th e combined
we ight of th e optional equipment we ighing more
th an th e re placed st andard parts and more th an
5 lbs (2.3 kg ). This optional equipment, such as
high-per fo rm ance brakes, le ve l control sy st em, a
ro of luggage ra ck or high-per fo rm ance bat te ri es,
is not included in th e curb we ight and th e we ight
of th e accessories.
TIN (Tire Identification Nu mber): a uni qu e
identification number which can be used by a
tire manufactu re r to identify tires, fo r ex ample,
in a product re call, and th us identify th e pur‐
ch asers. The TIN is made up of th e manufactur‐ er's identity code, tire size, tire type code and
th e manufacturing date.
Load-bearing index: th e load-bearing index is a
code th at con ta ins th e maximum load-bearing
capacity of a tire.
Tr action: traction is th e grip re sulting from fric‐
tion between th e tires and th e ro ad sur fa ce.
We ar indicator: nar row bars (tread we ar bars)
th at are distributed ove r th e tire con ta ct su rf ace.
If th e tire tread is le ve l with th e bars, th e we ar
limit of 1/ 16 in (1.6 mm) has been re ached.
Distribution of ve hicle occupants: distribution
of ve hicle occupants ov er designated seat posi‐
t ions in a ve hicle.
Maximum permissible pa yl oad we ight: nomi‐
nal load and luggage load plus 15 0 lb (68 kg )
multiplied by th e number of seats in th e ve hicle.432
Wheels and tires

Obser ve th e fo llowing when selecting, mounting
and re placing tires:R
Only use tires and wheels of th e same type
(summer tires, winter tires, MOEx te nded
tires) and th e same make.R
Only mount wheels of th e same size on one
axle (left and ri ght).
It is only permissible to ins ta ll a dif fe re nt
wheel size in th e eve nt of a fl at tire in order
to drive to th e specialist wo rk shop.R
Only mount tires of th e cor re ct size onto th e
wheels. R
Ve hicles with a tire pressure monitoring
sy st em: All moun te d wheels must be equip‐
ped with functioning sensors fo r th e tire
pressure monitoring sy st em.R
At te mp eratures below 45 °F (7 °C), use win‐
te r tires or all-season tire mar ke d M+S fo r all
wheels.
Wi nter tires bearing th e M snowflake sym‐
bol in addition to th e M+S marking pr ov ide
th e best possible grip in wintry ro ad condi‐
tions. R
Fo r M+S tires, only use tires with th e same
tread. R
Obser ve th e maximum permissible speed fo r
th e M+S tire mounted.
If th is is below th e ve hicle's maximum speed,
th is must be indicated in an appropriate label
in th e driver's fi eld of vision. R
Break in new tires at moderate speeds fo r
th e fi rs t 60 miles (100 km). R
Re place th e tires af te r six ye ars at th e latest,
re ga rd less of we ar. R
When re placing with tires that do no t fe a‐
ture ru n-flat ch aracteristics: ve hicles with
MOExtended tires are not equipped with a
TIREFIT kit at th e fa ctor y. Equip th e ve hicle
with a TIREFIT kit af te r re placing with tires
th at do not fe ature ru n-flat ch aracteristics,
e.g. winter tires.
