This was a HUGE issue for me when I first drove a Touring model. I loved the car except it seemed the cabin noise was too loud. Delving into the issue, I wondered if it was a function of the tire somehow. I used a sound meter app during my test drive and it showed the EX with the smaller tires was a few decibels lower than the better looking larger rims. I bought the EX, but really wish I had the premium sound that was not available on any of the smaller wheeled versions. I really wonder if it was more a function of the tread. Has anyone figured that out?
