Mercedes-Benz GLC : Wheels and tires / Notes on regularly inspecting wheels and tires
WARNING Risk of injury through damaged
tires
Damaged tires can cause tire pressure loss.
Check the tires regularly
for signs of
damage and replace any damaged tires
immediately.
WARNING Risk of hydroplaning due to
insufficient tire tread
Insufficient tire tread will result in reduced
tire grip.
In heavy rain or slush the risk of hydroplaning
is increased, in particular where speed is not
adapted to suit the conditions.
Thus, you should
regularly check the
tread depth and the condition of the
tread across the entire width of all tires.
Minimum tread depth for:
- Summer tires: â in (3 mm)
- M+S tires: ãin (4 mm)
For safety reasons,
replace the tires
before the legally-prescribed limit for
the minimum tread depth is reached.
Carry out the following checks on all wheels regularly,
at least once a month or as required, for
example, prior to a long journey or driving offroad:
- Check the tire pressure.
- Visually inspect wheels and tires for damage.
- Check the valve caps.
- Visual check of the tire tread depth and the
tire contact surface across the entire width.
The minimum tread depth for summer tires is
â in (3 mm) and for winter tires ã in
(4 mm).

Six marks
show where the bar indicators
(arrow) are integrated into the tire tread. They
are visible once a tire tread depth of approximately
1/16 in (1.6 mm) has been reached.
Make sure there are no vibrations, noises or
unusual handling characteristics when the vehicle
is in motion. This may indicate that the
wheels or tires are damaged...
WARNING Risk of accident due to incorrect
mounting of snow chains
If you have mounted snow chains to the front
wheels, the snow chains may drag against
the vehicle body or chassis components...
Other information:
How the restraint system works is determined by
the severity of the impact detected and the type
of accident anticipated:
Frontal impact
Rear impact
Side impact
Rollover
The activation thresholds for the components of
the restraint system are determined based on
the evaluation of the sensor values measured at
various points in the vehicle...
WARNING Risk of accident due to
reduced braking effect after washing the
vehicle
The braking effect is reduced after washing
the vehicle.
After the vehicle has
been washed,
brake carefully while paying attention to
the traffic conditions until the braking
effect has been fully restored...
