Thankfully the RLX will have this technology in the wheels, the ILX has a ton of road noise and it would suck if a top of the line Acura had it as well.

Not sure what 7 decibels is like but test driving one will do it for me.

Sometimes a manufacturer has tires made for a particular purpose, and Honda/Acura are famous for doing this with Michelin. Even though a tire might appear to have exactly the same name as your Acura's, it's possible that the ones on your car are different from the ones on a retail site.
