Tire-mount
ingtools should notbeused near
the valve. Thiscould damage theelectron ic
compon ents.
Only have tireschanged ataqualified spe-
cialist workshop.
Observe theinstr uctions andsafety notesinthe
"Changing awheel" section (Ypage 310).
The wear pattern son the front andrear tires
differ, depending onthe operating conditions.
Rotate thewheels beforeaclear wearpattern
has formed onthe tires. Fronttires typically
wear more onthe shoulders andtherear tires in
the cent er.
On vehicles thathave thesame sizefront and
rear wheels, youcan rotat ethe wheels accord-
ing tothe inter valsinthe tire manufact urer's
warranty bookinyour vehicle document s.Ifno
warranty bookisavailabl e,the tires should be
rotat edevery 3,000 to6,000 miles(5,000 to
10,00 0km ).Dependin gon tire wear, thismay
be required earlier.Donot change thedirection
of wheel rotation.
Clean thecont actsurfaces ofthe wheel andthe
brake discthoroughly everytimeawheel isrota-
ted. Check thetire pressure and,ifnecessary,
restart thetire pressure losswarning system
(Canada only)orthe tire pressure monitor(USA
only). Direction
ofrota tion
Tires withaspecified directionofrotat ionhave
additional benefits,e.g. ifthere isarisk ofhydro-
planing. Theseadvantages canonly begained if
the tires areinstalled correspon dingtothe
direction ofrotat ion.
An arrow onthe sidewall ofthe tire indicates its
correc tdirection ofrotat ion. Storing
wheels
Stor ewheels thatarenot being usedinacool,
dry and preferably darkplace. Protectthe tires
from oil,grease, gasoline anddiesel. Mounting
