I now have tires or have had or have driven cars with performance tires from the following: Kumhos, Yokohamas, Toyos, Dunlops, Pirelli P-Zeros, Bridgestones S02s, Continentals, Cooper and a few others.

....and none have been quiet on any of my cars. I'd probably guess that the Goodyear Eagles may have been a slight bit quieter but performance was not the same as the S03s or Pirellis on my 928s, etc.

Admittedly, each company makes dozens of different tire styles, tread designs, etc and it would be impossible for anyone person to try them all...and (like the oil debate) you'll always find someone claiming that tires I have found to be loud are quiet. Subjective thing I guess but I keep changing tire brands/types looking for a good quiet cruising tire that will go fast.

By their nature (stiff sidewalls) I think z-rated tires must all be noisy as a by product of their being good for the track and high speed.

The answer? Sound deadner, RMB, and a loud sound system. I just bought a boatload of deadner but haven't installed it yet.

PS: Wonder what Amzoil tires would be like?

They probably would leak,wouldn't seat properly and the sidewalls would scuff too readily. Then you'd have to become a dealer to get a good price. G

Actually if you believe the Amzoil hype their tires will out grip F1 tires. They'll be more quiet then anything else. They'll last 100,000 miles or 10+race seasons. In addition, they'll feed the starving children in Africa, end the middle east conflict, and most importantly, they'll cure erectile dysfunction (perhaps even make the equipment bigger.)

Closed cell foam in the space in front of the front rear wheel well liner. Some of the not-too-expanding great stuff in the cavity behind the 6 inch rear speakers.

I've done both of these, and tire noise is just about eliminated. And it cost very little.

Since none of the tires you tried so far are quiet, maybe it your expectation of "quiet" is the issue. How quiet do you expect them to be?

What?

The big bold agressive tread patterns which most expect on a high performance tire also gets them rated as mud and snow the M + S designation molded on the tire. They are all loud ! And all the airspace between the tread blocks does NOTHING for traction unless you are in water, mud , or snow Another victory of form over function.

ZR Rated ContiSports don't have stiff sidewalls, and they're very light, and fairly quiet.

Well, I just have to chime in on this. I have a 79 Euro, 50k miles and it is an auto. Stock exhaust, running Khumo Ecastas. (I know i must have mis-spelled something). My car is so quiet it surprises me. I think it runs and drives more like a late model BMW on rails rather than a 29 year old exotic. I never experience any tire noise or any other but that soft rumble from the back.

Buy a pretty tire that doesn't develop "teeth" from the block tread design. Make your alignment person a "believer" with regard to alignment protocols. G

Michelin PS2's may not meet your expectations .... but they are the quietest tires I've run from the 'ZR' category.

Well my Conti Sport Contact II's were fairly quiet when I first got them....them seem louder now, especially the rears that are less than 50%...... I like to think they got louder, but maybe driving my new Acura so much made the 928 seem louder than it is? I dunno

Gary Knox

Harvey,
The quietest tires I've run on the s4's and the GTS are Michelin Pilot Sport (original angled tread patterns design). I do have 17" wheels on both the current cars, so that helps in tire selection!

I'm in with Garth and Gary on the Michelins. I had the MXX3 pilots on the 17" rims when bought them, and they were so much quieter (and stickier) than the OEM-spec BFG's that I thought I'd hit the jackpot. The MXX3 Pilots were original on many Porsche cars earlier in this decade, including the C4 from which mine were removed. Except they didn't last very long, mostly due to a poor alignment and then my aversion to using the brake pedal in the local mountains.

Fast-forward to the PS-2 replacements, which are another order of magnitude quieter than the MXX3 versions. These are not the all-season version, but the summer performance version appropriate for the SoCal coastal desert climate. I love the quiet, love the grip, looks are fine, cost is higher than the Kumho's and Yoko's but worth it IMHO.

Dooing a casual search on Tire Rack for 16" tires, there was a BFG model that got great reviews including positive comparisons to the Michelin Pilot MXX3. Both quiet and sticky they said. I take a lot of these reviews with a grain of salt, mostly because the comparisons are biased towards the new tire over the memory of the old, bruised, worn-out carcasses that they replace. My reviews are probably biased similarly. In most cases, even a new inexpensive tire will "sound" and "feel" better than the worn-outs that just came off, right? So if you write a review after only a few hundred miles of new tire driving, of course they will be better than what was on there. Plus not many folks will ever write that they made a most horrible mistake buying the Pizzuzi's when all the reviews said they were great. I'm on my second set of front PS2's now, and did the rears for the first time with these new fronts so all are new. The new ones aren't significantly quieter than the ones that I took off, but at least there's a little more gap between the tops of the wear bars and the pavement.


I've ridden in a few other 928's in the ten years now since I bought mine. All of them had RMB's and tire noise was not noticeable. In the meanwhile, I really like quiet so the Michelins will probably get the nod from me until there's some experience that's head-and-shoulders above them. Ryan Perrella came by the house here for a look at his car a year or two ago, and we took my car for a quick ride to the polaps for brake fluid or something. He instantly commented on how quiet the car is, especially compared to his GT with RMB. I did a mini-PPI for SteveG's GTS over in Burbank, an RMB car with lots of extra tire and better shocks. Test drive was short, mostly because there was no good way to listen for car noises over the exhaust. H, maybe you can just get an RMB to mask the tire noise, then wear earplugs to mask the RMB din! Until then, get a ride in a car with the PS-2's and see if they will do the job for you.

WHY is silence so important?????????????????????????????????? 928's are Sportscars. I just don't understand the desire to have a whisper-quiet Lamborghini, Ferrari, Aston Martin, Maserati, Porsche. Maybe it's different strokes ..... personally, they can make as much noise as they like.

1) my engine drowns them out
2) their scrub noise gives me the feedback I need when cornering
3) as long as they keep my car planted, i don't care of they sound like a steel foundry
