I don't usually make long trips in my g37 sedan, but I just returned from a 400 mile trip and I was surprised how noisy the car is at 80 miles per hour. In my short local trips, I never noticed the noise. My car is a 2011 and has only 4,500 miles on it, so the car is in as new condition. Does it bother any of you?

 

when you say noise what do you mean ? engine noise / tires ??

 

If you have the 18" sport Dunlop Sport Maxx A/S th. Its dedefinitely the tires. They are extremely noisy especially if they arent wearing evenly.

 

If you have a G37S with RE050s - the tires are noisy...especially on concrete pavement. My wife's 'normal' G37 is much quieter...

 

Especially if you had bigger wheels. The double wishbone set up is not the quietest.

 

I did a 2000+ mile trip last spring down south. Lot of interstate then backroads once I got into the more interesting parts of KY/WV/TN/NC. I didn't think the car was overly loud. The only thing I found annoying was the engine whine in lower gears/higher rpms when railing the corners with the stereo off.

 

Yes, those are the tires I have. Thanks for letting me know, so I can replace the tires with a quieter brand. Which tires do you recommend for a quieter ride?

 

I just went through the very diligent process of determining which is the best tire for my G37s.

I decided on the Michelin Pilot Super Sports. This tire lives up to it reputation. Absolutely outstanding in all categories.

I previously had the stock Bridgestones on my G. They were good tires, some knock them because of tread life. But the wet/dry performance of the Bridgestones was outstanding and the profile of the tire looked very good on my G. Better than the pilots.

However, the Bridgestones, good as they were, were fairly noisy and rough at speed.

The pilot super sports feel like they outperform the Bridgestones in all categories. Especially in tire or road noise. The pilots are probably the quietest tire I have ever owned, my passengers even complement how smooth and quiet the car is at speed. They could not believe we were cruising at 90mph. Said it felt like 50.

Plus I run 13.6s at the track with them and love throwing it into a hard turn. These tires offer it all.

And..

For a cool $1k - they should.

 

I have the RSAs......they are fairly loud also. Frankly, my main disappointment with the G has been road noise on concrete....and wind noise from the back 1/4 windows. Prior to the G, I had an 04 Acura TL and 03 BMW 530, both were MUCH quieter.

I am sure different tires would help....but not solve the problem. It's a design issue IMO.
