450 Technical dataRims and tires
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar. Some vehicles may have sup-
plemental tire inflation pressure infor-
mation for driving at high speeds
(page 312) or for vehicle loads less
than the maximum loaded vehicle con-
dition. If such information is provided,
it can be found on the placard located
on the inside of the fuel filler flap. The
tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance recom-
mendation included with vehicle.
iThe following pages also list the ap-
proved wheel rim and tire sizes for
equipping your vehicles with winter
tires. Winter tires are not available as
standard or optional factory equip-
ment, but can be purchased from an
authorized Mercedes-Benz Center.
Depending on vehicle model and the
standard or optional factory-equipped
wheel rim/tire configuration on your
vehicle (Appearance Package, Sport
Package etc.), equipping your vehicle
with winter tires approved for your ve-
hicle model may also require the pur-
chase of two or four wheel rims of the
recommended size for use with these
winter tires. See an authorized
Mercedes-Benz Center for more infor-
mation.

!Please compare the recommended tire
inflation pressure for your vehicle with
the tire inflation pressure on the yellow
label located on the spare wheel rim.
If the tire inflation pressure on the yel-
low label on the spare wheel rim differs
from the values given in this Operator’s
Manual, inflate the spare wheel tire to
the recommended tire inflation pres-
sure given on the yellow label on the
spare wheel rim.
iPlease note that the tire inflation pres-
sure of the Minispare tire and the
collapsible tire differs from the tire
inflation pressure of the road tires.
Make sure the Minispare tire is inflated
to approximately 61 psi (4.2 bar).
Inflate the collapsible tire to approxi-
mately 51 psi (3.5 bar).
iThe CLS 55 AMG with Performance
Package* does not have a spare wheel.
