The Consumer Reports review of the G35 showed much more noise and rougher ride quality with the 18" tires over the 17" tires. If you want quiter/smoother at the sacrifice of performance you have a choice.

 

I agree with you nimnix, I concentrate on the thrill of the ride (except while in traffic) rather than the road noise. Throw some smooth jazz with my upgraded Panasonic/MTX/Infinity Kappas sound system, push the throttle and enjoy the ride. I did not intend for my G to be a library, where the librarian says " SHHHHHHHHHHHHHHHHHH!"

Maybe once the honeymoon period of riding the 280 horsies is over (which is hopefully never), I'll be more aware of the road noise. Till then, the growl of the exhaust, the whistle of the Z intake and the silkiness of David Benoit will keep me occupied. Ahhhhhh......

 

I noticed my car can get loud especially on concrete highways.

I currently have the Goodyear Eagles which are known to be noisy even on other cars (See TireRack). But let's be for real. High-performance tire are rarely quite.

As I stated earlier, I plan on Dynomatting my car when I install the stereo/carputer(?). I hope this will calm things down a bit.
