2020 MERCEDES-BENZ GLA SUV Owner's Manual

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 thedirec-
tion ofwheel rotation.
Clean thecont actsurfaces ofthe wheel and
the brake discthoroughly everytimeawheel
is rotat ed.Check thetire pressure and,ifnec-
essary, restartthetire pressure losswarning
system (Canada only)orthe tire pressure
monit or(USA only). Direction
ofrota tion
Tires withaspecified directionofrotat ionhave
additional benefits,e.g. ifthere isarisk of
hydroplaning. Theseadvantages canonly be
gained ifthe tires areinstalled correspon ding
to the 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
