514 Wheels and tyres
the tyres rubbing against the body and axle
components when loaded. This could result
in damage to the tyre or the vehicle.
Only use tyres, wheels and accessories that
have been checked and recommended by
Mercedes-Benz.
* NOTE Risk to driving safety from retrea‐
ded tyres
Retreaded tyres are neither tested nor rec‐
ommended by Mercedes-Benz, since previ‐
ous damage cannot always be detected on
retreaded tyres.
For this reason driving safety cannot be guar‐
anteed.
Do not use used tyres if you have no
#
information about their previous usage.
* NOTE Possible damage to wheels or
tyres when driving over obstacles
Large wheels have a lower tyre section width.
The lower the tyre section width, the greater
is the risk of damage to wheels or tyres when
driving over obstacles.
Avoid obstacles or drive particularly
#
carefully.
* NOTE Damage to electronic component
parts from the use of tyre-fitting tools
Vehicles with a tyre pressure monitoring
system: electronic component parts are
located in the wheel. Tyre-fitting tools should
not be applied in the area of the valve.
The tools could damage the electronic com‐
ponent parts.
Have the tyres changed at a qualified
#
specialist workshop only.
* NOTE Damage to summer tyres at low
ambient temperatures
At low ambient temperatures, tears could
form when driving with summer tyres, caus‐
ing permanent damage to the tyre.
At temperatures below 7 °C, use M+S
#
tyres.
Accessory parts that are not approved for your
vehicle by Mercedes-Benz or are not being used
correctly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist workshop
and enquire about:

& WARNING Risk of accident with high
performance tyres
The special tyre tread in combination with
the optimised tyre compound, means that
the risk of skidding or hydroplaning on wet
roads is increased.
In addition, the tyre grip is greatly reduced at
a low outside temperature and tyre running
temperature.
