Wheels and tyres

653

Visually inspect wheels and tyres for damage.

Check the valve caps.

Visual check of the tyre tread depth and the

tyre contact surface across the entire width.

The minimum tread depth for summer tyres is

3 mm and for winter tyres 4 mm.

Notes on noise or unusual handling characteris-

tics

WARNING Risk of aquaplaning due to

insuﬃcient tyre tread

Make sure there are no vibrations, noises or

unusual handling characteristics when the vehicle

is in motion. This may indicate that the wheels or

tyres are damaged. Hidden tyre damage could

also be causing the unusual handling characteris-

tics.

If you suspect that a tyre is defective, reduce your

speed immediately and have the tyres and wheels

checked at a qualiﬁed specialist workshop.

Insuﬃcient tyre tread will result in reduced

tyre grip.

The risk of aquaplaning is increased on wet

roads, especially when the speed of the vehi-

cle 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 tyres.

WARNING Risk of accident due to incor-

rectly ﬁtted snow chains

Minimum tread depth for:

If you have ﬁtted snow chains to the front

wheels, they may drag against the vehicle

body or chassis components.

Summer tyres: 3 mm

M+S tyres: 4 mm

Notes on regularly inspecting wheels and tyres

WARNING Risk of injury due to damaged

tyres

For safety reasons, replace the tyres

before the legally-prescribed limit for the

minimum tread depth is reached.

Never ﬁt snow chains to the front

wheels.

Damaged tyres can cause tyre pressure loss.

Only ﬁt snow chains on the rear wheels

in pairs.

Check the tyres regularly for signs of

Carry out the following checks on all wheels regu-

larly, at least once a month or as required, for

example, prior to a long journey or driving oﬀ-

road:

Vehicles with Active Parking Assist: do not use

Active Parking Assist when snow chains are

ﬁtted.

Vehicles with level control: if snow chains are

ﬁtted, only drive at raised vehicle level .

The tyres can wear excessively and/or

unevenly.

The driving characteristics as well as the

steering and braking characteristics may

be greatly impaired.

NOTE Damage to components of the vehi-

cle body or chassis due to ﬁtted snow

chains

If you ﬁt snow chains to the front wheels of

4MATIC vehicles, you may damage compo-

nents of the vehicle body or chassis.

You can permanently limit the maximum

speed for driving with winter tyres

(/ page 349).

You can deactivate ESP^®to pull away

(/ page 340). This allows the wheels to spin,

achieving an increased driving force.

Comply with the recommended tyre

pressure and check the tyre pressure of

all tyres, including the spare wheel, regu-

larly:

Only ﬁt snow chains to the rear wheels

of 4MATIC vehicles.

Observe the following notes when using snow

chains:

monthly

when the load changes

before embarking on a longer journey

if operating conditions change, e.g. oﬀ-

road driving

Snow chains are only permissible for certain

wheel/tyre combinations. You can obtain

information about this from a Mercedes-Benz

Service Centre.

Underinﬂated or overinﬂated tyres pose in par-

ticular the following risks:

Shorten the service life of the tyres.

Comply with the installation instructions of the

snow chain manufacturer.

If snow chains are ﬁtted, the maximum per-

missible speed is 50 km/h.

Cause increased tyre damage.

The tyres can burst.

Adversely aﬀect driving characteristics and

thus driving safety, e.g. due to aquaplaning.
