I had a 2006 Mercedes and my wife had a slow tire leak. She rolled into a tire center- they put on a new tire. Same brand. Shortly after that she reported the car was not running right- she would start to pass someone and the power would drop off.
After this went on for a while - I took the car and it was crazy- any acceleration and bingo- power drop. We took it into the dealer- after a few hours they found the tire size was off by one size down. Easy fix.
So fix it
