Hello, I have a 2012 S550 4Matic completely stock and have a set of 19 inch rims and tires for my Mercedes that I am putting on for the winter season. I bought the car used and the previous owner had done the same thing with the same set of wheels he gave me because he said he used them during the winter time. My question is... if I currently have 18 inch wheels on it and I put on the 19 inch wheels (after balancing them of course) do I need to go to have an alignment done?

 

Plain and simple - nope ! :-)

 

No wheel alignment but might need to get wheels balanced if they haven’t been done do previously
