New member here, wanted to chime in. I happen to stumble upon this forum after doing a Google search on the GLC300 Tire problem. The search did show a good amount of reported issues regarding this topic. I was expecting to see more on this forum besides the 4 posted above (unless I'm looking in the wrong place). Around 9,500 miles I started noticing a vibration that was noticeable in the brake pedal. As time went on, it became increasingly worse. Extremely noticeable in the steering wheel. I was driving home from vacation at the beach and I had a hard time controlling the car at highway speeds. I knew I had an appointment with my Mercedes dealer in two days for my 10K Service A. In 2 weeks it will be my 1 year anniversary with my GLC with 10,400 miles. While at my service appointment, I explained exactly what I was experiencing and told them the car is not safe to drive. After inspecting, they said the tires are shot and need to be replaced, they stated they were "Feathering". I had never heard that term before, but I have been reading a lot about it. My advisor told me the Pirelli Scorpion's are junk and they do not recommend using them as my replacement tire. They quoted me a price using Continentals or Michelin's. Well at 10K miles and under 1 year of ownership, I SHOULD NOT BE BUYING TIRES. I did not replace the tires yet, I wanted to do a little digging and research, PLUS, I don't have an extra $1400 on hand.
My 4th Mercedes, I really don't want it to be my last.
A couple of questions:
Is it true you have to put on or use MB approved tires?
Anytime I have bought a car (I've bought a lot too), there was always a tire warranty booklet in the packet of documents, there is none for the Pirelli's, should there have been or are they not warranted?
If Pirelli does not stand behind their product, does Mercedes stand behind theirs?
Any recommendations for replacement tires...
FYI, I did open up a ticket with MBUSA this afternoon, I actually did this because the vehicle is unsafe to use, so if something should happen, I wanted it on record.
One more question...
Do I have the option of NOT replacing Run Flat tires with standard tires? It's not leased, financed.
