Tread; Wear - Mercedes-Benz Vito Operating Instructions Manual

Run in new tyres at moderate speeds for
the first 100 km.
G
Risk of accident
Loose wheel nuts or bolts could cause you
to lose a wheel while the vehicle is in mo-
tion. You could lose control of the vehicle as
a result, cause an accident and injure your-
self or others.
You should therefore tighten the wheel nuts
or wheel bolts regularly, at least once a
year, to the specified tightening torque.
You will find further information on winter
tyres in the "Operation" section
e
( page 235).
You will find information about the tighten-
ing torque for wheel bolts in the "Technical
data" section ( e page 354).
Tyre pressures
G
Risk of accident
Always observe the specified tyre pressures
for your vehicle.
The tyre temperature and pressure increase
when the vehicle is in motion. You should
therefore never reduce the pressure of
warm tyres. The pressure would then be too
low once the tyres have cooled.
The tyre pressure must be adjusted to the
load of the vehicle. If the tyre pressure is
too low, it may cause the tyre to burst, es-
pecially at higher loads and speeds. A tyre
pressure that is too high can cause a longer
braking distance and a poorer tyre grip.
If the tyre pressure has been incorrectly set,
you could lose control of your vehicle, caus-
ing an accident and injuring yourself or
others.
Check the specified tyre pressure regularly
when the tyres are cold. You should do
this at least once every two weeks and be-
fore long journeys.
Correct the tyre pressure before loading
the vehicle. Check tyre pressures after
loading the vehicle and correct them as
necessary.
I If the tyre pressure is too low, it can
cause excessive tyre temperatures, in-
creased tyre wear, altered directional
stability and increased fuel consump-
tion.
I If the tyre pressure is too high, it can
cause a longer stopping distance, poor-
er tyre grip and increased tyre wear.

Tyres and wheels
Valve caps on the tyre valves protect
I
the valve core from moisture and dirt.
You must therefore always screw the
valve caps tightly onto the tyre valves.
If there is repeated pressure loss from
I
the tyres, this may be caused by exter-
nal damage, foreign objects in the tyre
tread, cracks, bulges or leaking tyre
valves.
You will find the tyre inflation pressure ta-
bles in the "Technical data" section
e
( page 352).
Tyre tread
A minimum tyre tread depth is specified
by law. You should therefore observe the
respective legal requirements for the rele-
vant country.
I The smaller the remaining tread depth,
the poorer the grip and handling of the
vehicle will be, especially on wet or
snow-covered road surfaces.
I When the tread depth is less than
3 mm, tyre grip is drastically reduced
on wet roads, for example. For safety
reasons, you should have the tyres re-
placed before they reach the minimum
tread depth specified by law.
