btw, the tyres are bridgestone. with my previous accord, changed to bridgestone couple years ago to the front wheels and more road noise enter cabin. few months afterward changed the rear tyres but this time stick to original michelin energy and rotate the michelin to front, noise seems to be better. could be bridgestone tyres too hard?

not sure if tyres are the reason but if it is, would be easy to solve.... cross my finger that it is from the tyres and not something more serious...
