Ok picked up my car tuesday(c300 sport amg 4 matic) and just noticed a huge knot on my tire called continental they said to bring it to mercedes and they will come look to see if its covered.On the paper it looks like they do not cover damage .i didnt hit anything so have no idea how it got there but i do drive in new york the worst roads in the country so who knows ,but has anyone had continental replace there tire

ps- NO iu did not purchase tire insurance through benz

 

Sounds like a manufacturing fault which would carry warranty.

 

There is a tire recall from Continental that covers some tires on the US C300 (and perhaps other models). Check with Continental or your dealer to see if your are covered. My fronts were replaced at 5k miles at no charge to me.
