I purchased a 2009 smart fortwo passion in July advertised with new tires. Most everything ran fine until November. On the same night my tire went flat, radiator fan died, and the radiator cracked. After having it towed to a Mercedes dealership for repair, they tell me that whoever installed the tires previously installed them incorrectly. The bigger and smaller tires are switched instead of being in the proper place. I don't know if this would have caused the flat, but from what I understand, driving like this can cause damage to my suspension and transmission. Does anyone know of anything else that needs to be checked due to this? I don't want to risk not checking for damages and messing up the vehicle.
