Changing A Wheel - SMART fortwo coupé Owner's Manual

Check the tyres regularly for signs of dam-
age and replace any damaged tyres imme-
diately.
G
WARNING
Insufficient tyre tread will reduce tyre
traction. The tyre is no longer able to dis-
sipate water. This means that on wet road
surfaces, the risk of aquaplaning increa-
ses, in particular where speed is not adap-
ted to suit the driving conditions. There is
a risk of accident.
If the tyre pressure is too high or too low,
tyres may exhibit different levels of wear
at different locations on the tyre tread.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres.
Minimum tyre tread depth for:
summer tyres: 3 mm
R
M+S tyres: 4 mm
R
For safety reasons, replace the tyres before
the legally prescribed limit for the mini-
mum tyre tread depth is reached.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres.
Modification work on the brake system and
wheels is not permitted. The use of spacers or
brake dust shields is not permitted. This
invalidates the general operating permit for
the vehicle.
Check the wheels and tyres for damage at
least once a month, as well as after driving
off-road or on poorly surfaced roads.
Run-in new tyres at moderate speeds for the
first 100 km. The tyres only attain their max-
imum performance after this distance.
Vibrations, audible noises and unusual han-
dling characteristics, e.g. pulling to one side,
can indicate damage to wheels or tyres.

G
WARNING
Never interchange the front and rear
wheels as they have different dimensions,
e.g. size, offset etc. Otherwise, there could
be a negative effect on the road holding
and you could endanger yourself or others.
G
WARNING
Exceeding the stated tyre load-bearing
capacity and the approved maximum
speed could lead to tyre damage or the tyre
bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe
the tyre load rating and speed rating
required for your vehicle.
G
WARNING
If wheels and tyres of the wrong size are
used, the wheel brakes or suspension com-
ponents may be damaged. There is a risk of
an accident.
Always replace wheels and tyres with
those that fulfil the specifications of the
original part.
When replacing wheels, make sure to fit
