I have a 2009 Acura TL w/tech package. I love driving this car. It's a lot of fun, but it's a bit noisy - I normally have a podcast or the radio on, buth it's off when the wife is in the car. The suspension is a bit stiff and the road noise is a bit excessive. I am thinking about replacing the tires - 245/50/r17 currently have the Michelin Pilot MXV4. The tread left is still decent, but do you think i'd get a noticeable noise difference if I replace them with the primacy MXV4?
