!Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the spare wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the spare
wheel tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.
iPlease note that the tire inflation pressure of
the Minispare tire differs from the tire inflation
pressure of the road tires.
Make sure the Minispare tire is inflated to ap-
proximately 61 psi (4.2 bar).
iThe CLK 63 AMG cabriolet does not have a
spare wheel. The CLK 63 AMG cabriolet is
equipped with TIREFIT, see “Sealing tires with
TIREFIT (CLK 63 AMG only)” (
