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...

WARNING Risk of accident and injury
caused by an insufficiently secured vehicle
rolling away
If the vehicle is not securely parked sufficiently,
it can roll away in an uncontrolled
way even at a slight downhill gradient.
On uphill or downhill
gradients, turn the
front wheels so that the vehicle rolls
towards the curb if it starts moving...
