390 Wheels and tires
Check whether the wheel or valve has a
#
leak.
If you are unable to rectify the damage,
#
contact a qualified specialist workshop.
You can find information on tire pressure for the
vehicle's factory-installed tires on the following
labels:
Tire and Loading Information placard on the
R
B‑pillar of your vehicle ( page 393).
→
Tire pressure table on the inside of the fuel
R
filler flap ( page 390).
→
Observe the maximum tire pressure
( page 399).
→
Use a suitable tire pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure.
Only correct tire pressure when the tires are
cold. Conditions for cold tires:
The vehicle has been parked with the tires
R
out of direct sunlight for at least three hours.
The vehicle has traveled less than 1 mile
R
(1.6 km).
A rise in the tire temperature of 18 °F (10 °C)
increases the tire pressure by approx. 10 kPa
(0.1 bar/1.5 psi). Take this into account when
checking the tire pressure of warm tires.
The tire pressure recommended for increased
load/speed in the tire pressure table can affect
the ride comfort.
& WARNING Risk of accident from unsuita‐
ble accessories on the tire valves
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Tire pressure monitoring systems for
retrofitting will cause the tire valve to remain
open. This can also result in tire pressure
loss.
Only screw standard valve caps or valve
#
caps specifically approved by
Mercedes-Benz for your vehicle onto
the tire valve.
Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap.
% The data shown in the images is example
data.
The tire pressure table shows the recommended
tire pressure for all tires approved for this vehi‐
cle. The recommended tire pressures apply for
cold tires under various operating conditions, i.e.
loading and/or speed of the vehicle.
If one or more tire size precede a tire pressure,
the tire pressure information following is only
valid for those tire sizes.
