I have a 2011 E350 that has less than 20,000 miles on it, and already the rear tires need to be replaced, according to the dealership. The tires are very loud at highway speed.

It has the Pirellis. Is this normal for this car and tire?

Thank you

 

I had a c230 and they are known for going through rear tires.Traded it in with 60000km and replaced the rear at 48000km front still looked new on trade in.

 

I had the same problem on my E320.
