visible damage. Yo
u can recognise MOExtended tyres bythe
MOExtended marking which appears on the side
wa ll of the tyre.

When replacing with tyres that do not
fe ature run-flat characteristics: vehicles
with MOExtended tyres are not equipped
with a TIREFIT kit at thefa ctor y.Equip the
ve hicle with a TIREFIT kit af terre placing with
tyres that do not feature run-flat characteris‐

s on inter changing wheels &
WARNING Risk of inju rythro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions may se
verely impair the driving characteris‐
tics.
The disk brakes or wheel suspension compo‐
nents may also be damaged. #
Rotate front and rear wheels on lyifthe
wheels and tyres are of the same
dimensions. Inter
changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions can
re nder thege neral operating pe rmit in valid.
The wear pat tern s on the front and rear wheels
dif fer:
R Front wheels wear more on the shoulder of
th e tyre
R Rear wheels wear more in the cent reofthe
tyre
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5,000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels. It is imperative
toobser vethe instructions and
saf ety no tes on "Wheel change" when doing so. Note

Afterre moving wheels, store them in a cool,
dry and preferably dark place.
R Protect the tyres from conta ct withoil,
grease or fuel. Overview of
the ty re-change tool kit Apart from some countr
