Going for non RUN FLAT
I used to have a GL320 CDI and had the Pirelli Scorpion - a RUN FLAT.
It was noisy after 20,000km.
But since I changed to one of those cheapo brands, it was quiet throughout its life of 50,000km.
Now I have GLC 250cdi and still stuck with Pirelli Scopion Verde (RUN FLAT).
A bit noisy when there is load (people) at the back.
Is there any special selection /option on the dash or setting when I don't use run flat for GLC?
(I did not need to do anything on the GL, as well as my missus B-class when I switched to a non run flat)
