Nismo howling noise over 70mph?
 

I am a new owner of a 09 370z Nismo with 47K and I hear a howling sound from the rear of the car when going over 70 mph. Does anyone else experience this?

Is this just road noise? Depending on what type of surface your riding on, the tires noise translates into the cabin, and can be pretty noisy on crappy roads.

Not sure if it's the same noise you are hearing, mine sound like a jet(high pitched whining) on the highway. Yes, our car has a lot noises not only from tires.

I hear mostly road noise (now exhaust drone) with the windows up. I have noticed a slightly jet sound as mentioned above. I think it's pretty normal.

get your alignment checked, also check your tires to see if they are cupped. if the alignment and the tires are fine, then it's probably just "normal" road noise for this car, there's a lot of it.

This is exactly the noise that I am talking about! Sounds like its coming from the the passenger side rear wheel. I checked and the tire does not to seem to have any cupping. Thanks for all the replies, loving this forum!
