Road Noise

Road Noise
I bought an RX8 about a month ago because I got a new job and needed something to show for it. The problem I have is with the road noise. When I test drove the car I drove it on the streets and didn't go past 45mph. After I bought it and took it home, I began to notice excessive road noise when I drove on the freeway. There are also a few rattles inside which I don't like at all either. Is there anything that can reduce road noise for the RX8?

While I wouldn't call the 8 a "quiet" car, for a sports car it's fairly quiet on the highway.
Different brands of tire vary widely on road noise. Go to tirerack.com and you'll find surveys where all the tires are rated on many factors, including road noise. See if the tires your 8 has are especially noisy. If so, consider buying quieter tires.
Also, make sure your tires at at 32psi.

+1 to the noise of older stock Bridgestones. By the time that I got rid of them it was like driving inside a speaker at a Metallica concert. With good tires, it is actually a pretty quiet car.
As for rattles, there is a piece of styrofoam that can come loose and rattle in the doors which can be fixed with a little glue. Other than that, my car seems to be pretty quiet so I don't know.

Wow thanks for all the quick info guys. I owned an integra before this car and I was getting upset with this car because the freeway noise is almost as bad as it was on that one.
I have the Dunlop stock tires. It's a 2004 and I bought it with 14k miles on it. The tires say 51psi max so why should I only inflate to 32? Most of the noise now that I listen to it seems to be coming from the rear tires so I'm guessing they might not be aligned properly. I'll check out different tires and see if it helps.

They get flat spots in the summer time but go away after you drive for about a block or two.

The Maximum inflation on the tier only tells you how much pressure you can put into the tire before it will blow the sidewall out.
The manufacturer of the car sets the tire pressure for the suspension set up that they have, and you can find that optimal number in your owner's manual. I can't remember what it is exactly, but I run mine at 31PSI, and I know that it is right around there.
The reason that you don't run them at 51PSI is because your car will skitter around the road like you are running on bowling ***** ... because basically you are. It makes the handling very nervous and unsafe. Also any bump in the road is like running over a boulder. It causes tremendously uneven tire wear and can destroy a set of tires in just a couple of thousand miles, and all in all it is just a bad idea.
14 thousand miles on the rears if they were driven by someone with a lead foot and didn't rotate them, they could have worn out treads.

Also, if you live in a cold climate, the stock tires are summer only, and can get very hard in Winter making them unsafe to drive on winter roads. All the best.

If the ( fix-a-flat ) was use to fix a flat, then the tire will be out of balance. The tire will need to be removed, and the **** wiped out. then balanced.

I was looking on tirerack.com and the potenzas actually seemed to rate very highly for road noise. Better than most of the other tires I looked for in fact. Does anybody want to give me a few options to look for? I don't care about cost all that much. I just want to get my car to sound and ride better.

I got the continental contiextremecontact (That's seriously how they write it)

I bought them because I'm too cheap to have two sets of tires and they're highly rated for the price.

I was looking at these.

Everything is rated very highly for these so I'm taking a good look at them. What are the stock ones?
I'm looking for all-season tires that can handle rain really well because I get some snow and a lot of rain in Oregon. These look like the best choice so far...

Yet only $139 in stock 225/45/18 fitment. Less for other useable sizes. I can't see a better value with performance and quiet than that. Read the tire test they did - amazing for $139 and relatively lowkey brand.
