Notes on replacing tyres and retreaded tyres
Replacing tyres
If replacing the standard tyres of your vehicle,
use only the tyre and wheel disk sizes approved
for your vehicle type.
A tyre dealer, a qualified specialist workshop or a
Mercedes-Benz Service Centre will be able to
provide you with further information. After replac‐
ing your tyres, carry with you the vehicle's type
approval for the new tyre and wheel disk size as
well as the manufacturer's certificate showing
that the tyres may be used on the vehicle.
Observe the legal requirements for the country
you are currently in. A Mercedes-Benz Service
Centre can provide you with information on
obtaining a manufacturer's certificate.
After replacing your tyres, it may be necessary
for adjustments to be made to the control units.
If necessary, have these adjustments carried out
at a qualified specialist workshop.
Vehicles with power steering: if you change the
mechanical axle stops, e.g. when changing a tyre,
have the power steering taught-in at a qualified
specialist workshop.
Retreaded tyres
Mercedes-Benz recommends that you only use
tyres and wheels that have been approved for
Mercedes-Benz.
Balancing tyres
Mercedes-Benz recommends that you only use
clip-on and adhesive wheel balance weights
which have been approved for Mercedes-Benz to
balance the tyres. Adding balancing granulate,
balancing beads or balancing gel to the tyres can
damage the inliner of the tyre.
