2014 C300 4-Matic Unbalanced Tire Noise
I just purchased a new 2014 C300 from a dealer in NH. At 1,500 miles I started to hear a drastic unbalanced tire noise from the right rear tire. The dealer looked at it and determined all 4 tires were cupping and replaced them all and did a new alignment. I am 300 miles into the new tires and the noise is coming back again. Has anyone experienced anything like this? The dealer is going to look at it again this week but said there are no visible issues e.g. suspension issues or such and the alignment was "spot-on" from the factory. Any info is appreciated so I am armed with data when I go into the service department. Thanks

Obtain the before & after readings from the alignment & check with the MB figures.
It must be still out.
The correct toe in figure I have is 0'10' ( + or - 10') or individual -.6mm to +.6mm.
My cars tyres were cupping when new & the individual toe was +.7 mm This was reduced to +.3 & all has been well since.
