Yes the cold spotting was severe for the first few hundred KMs and once the tyres were run in it has reduced but still noticeable if you driven on smooth roads and while braking hard. It settles down within a 2km. Similar issue was noted with made in Germany OE Goodyear NCT 5. Later model C-class with NCT5 205/55R16 did not show this cold spotting, so I assume that it may be due to higher 65% profile.
The new S class comes with Goodyear Excellence.
At the auto expo, Skoda Fabia was having 17" Excellence. Infact there were few more cars with Excellence tyres.
