Please tell me these are NEW tires.... If it's that obvious, then this is clearly your problem. Do you have 16" or 17" wheels? The bigger the wheels, the more sensititve to imperfections - low profile rubber is less compliant. On top of that, these cars are more "precise" than let's say ...a Ford, Camry, etc. so you feel much more, even the annoying stuff.
