Any opinions on which 20" tire will make the least noise? I find the Pirellis on my new C4 to be pretty noisy.

I'm not concerned about track performance and would only consider swapping out my new tires for another set if there was a considerable noise reduction.

Any thoughts?

 

continentals run very quiet, pirellis just notorious for their noise/hardness once past the first 20-25%

 

are you talking about run flat tires

 

New ones.

 

Michelin Pilot Super Sport are supposed to be less noisy than Pirelli.

 

I'm here today because I am putting off doing other things. But, LexVan's sense of humor, as usual, makes time spent here worthwhile.

Maybe the new Continentals? I have the older Extreme Contact DW tires on my 993 and they are certainly quiet, though not really very sticky. Then again, it seems everybody believes the Michelins are both quieter and better than what you have now, either the Super Sports or the new version "4."

 

I just switched from semi-new (50%) PZeros to new Michelin Pilot 4S's and the noise reduction is definitely noticeable.

 

My car and tires have 250 Kim's on them. They are quite noisy and was hoping there is a noticeably quieter option out there for street use.

 

We need the guys at Tire Rack to do a test on both tires, over the same roads at the same speeds. In my experience, the texture of the road surface makes a significant difference in tire noise.
A simple cell phone app would provide a way to quantify the data, instead of relying on the drivers feeling.

 

Bridgestone Potenza S-04 Pole Position tires that I installed after shelling my P-Zeros are noticeably quieter, and *much* better on the wet roads that are quite common in my area. They've been just fine on the track this year, too. I wouldn't hesitate to recommend them. The 20" S rims came on my car.

You might also monitor your pressures a little bit. 32 fr, 36 r with these tires seems to work well.

 

I agree. My car on an average highway surface (so not new fresh smooth asphalt) shows 93db at 100 km/h. That is about the same volume level as flying on a 737 jet airliner. My BMW 5 series had an interior reading of 83 on the same stretch of road.

As much as I've been in love with the idea of owning a 911 for decades, I find the combination of interior "drone" from the rear of the car at 2,200 RPM (where the car seems to spend a lot of its time in city driving) and the tire roar, to be too much for my tinnitus.

If blocked symposers and quieter tires can bring the noise levels down, I'd be OK, otherwise this car will get traded for a Panamera.

 

On some concrete roads I am sure it's even worse. I should be wearing noise cancellation headphones, but most of the time that engine noise is beautiful on blacktop

 

I blocked the symposer with a rag, and it was a noticeable improvement.
I'm hoping tires are the finishing touch.

 

Have to try this also. How difficult was taking that rear piece off and then back on in the car to get to the symposer. What type of rag, microfiber? I assume it's nothing other than noise and not heat coming thru now.

Did you use any tape to hold it on

Thanks

 

If the car is too loud for you in Normal (non-sport) mode then blocking the symposer will do nothing for you. The tube is only opened in Sport modes.
