I've installed a sound meter app on my Galaxy Player.

Has anyone used this or a similar app to measure the noise level in their 350Z equipped with something other than the OEM Potenza tires? If so, please post the brand of tires, the noise level readings, and other info (mods, etc) that may be useful in determining what brand will offer the lowest noise level in the Z.

 

Lots of factors other than just brand/model will affect the noise levels.

 

What I'm really hoping is that some people will provide sound level measurements before and after changing tires on their cars. If that doesn't happen, the "other info (mods, etc)" might help make useful comparisons between brands.

 

Also take into consideration, that ultra high performance tires such as the original equipment Bridestone RE40/RE50 and others in this class (Michelin PS2 etc.) get substantially nosier as they wear down.

 

Is this a personal observation? I would think they'd become less noisy as the tread wears. Never really gave the issue much attention myself, which is why I'm asking.

 

Wow.

Doesn't surprise me this lady wants the quietest tires. Wrong car pizza girl.

 

You would be wrong.

Most front tires on Z's feather and get "cupped"

This makes them VERY noisy at certain speeds. Usually slower speeds, windows down it sounds and feels like you're riding on pucks, can emit a constant houl.

 

My initial reaction to your post was that this guy has too much time on his
hands and may have gone app crazy lol.I'm sure fellow forum members will chime
in with their thoughts just based on experience.I sure can.In addition,I have
found tire reviews like the ones offered by Tire Rack to be meaningful in
selecting tires.Everyone has a specific focus on buying tires.Some want
performance,the hell with the noise.Its not a factor.Ride comfort,wet/dry
weather etc.As what wasalready mentioned(and from my experience)performance
tires tend to get noisier as they wear.A quiet tire is a major factor to me.
So,you have got my attention.Saying that,I HIGHLY recommend Hankook
V-12's if you want a quiet perfomance tire.Overall,its a fantastic tire unless
you are a serious performance guy(rather soft sidewalls).

 

Disagree...won't happen if your front is set up correctly.
For sure,having a 03 Z,I've had the front tire feathering curse.
After 3 sets of fronts(warranty),I finally found a Nissan shop that
knew how to set up the car correctly.My fronts have little to
no wear.Rear tires will wear a bit inside due to the camber.
Its difficult to find someone that has the know how to
set the front end on a Z correctly.Suggest you find the right shop.

 

I'm not even talking about noise from other mods, I mean the tire noise volume is dependent on lots of things. Tire pressure, alignment, wear, road surface, speed. Not to mention it would be inevitable that each recording would be in vastly different acoustic environments. There are lots of variables that need to be regulated and controlled for this experiment to work.

And for the louder as they wear discussion, I have two sets of the same exact tire and exact same sizes, one set has way more tread and is much much quieter.

 

Obtaining reliable tire noise values is done in a laboratory setting where it’s possible to duplicate the test environment. I don’t think you will get accurate readings from a precise instrument in a real driving situation where the environment can vary.

A few variables that can make a significant difference are tire wear, road surface, speed, tire psi, weather conditions, and temperature.

You propose and interesting study, but we need more controls to obtain accurate data.

^^^ totally plagiarized me br0

 

^^ Don't compliment yourself. I didn't even read your post... only the OP's. I wonder if you know the specifics when tire manufacturers run comparative tests?

You mention the obvious. If we agree that's good.

Your car simply isn't set up correctly if you're having that problam. Find a better alignment shop. My '08 has 52K on it now, and has never had that issue, either with the OEM Bridgestones or the subsequent Falkens. While the rears have always worn out faster, and more on the inside edge than outside, my fronts have always worn down clean and evenly. My inquiry is whether properly worn tires are more noisy than new, and I have no interest in what happens with abnormal wear like cupping. Of course, that will cause noise, and other issues as well, that should be dealt with sooner than later.

 

^^ dcains … That is a good question.

My experience is that summer performance tires become noisier with wear.

Being that my career has nothing to do with manufacturing or testing tires, no. Your point?

 

^^ That means you and I offer guesses and never expert comments about tires (i.e., we are dummies in this arena).

Is that what you are asking? --Spike

 

Just visit Tirerack's website and see what people say about tire noise for the tires you're interested in. The method is a bit subjective, but all things being equal, you're never going to get a reliable measurement unless you use the same car on the same stretch of road with a whole bunch of different tires.

 

^^ Yes... And stated in a way that everyone understands. --Spike

 

Surely a lot depends on the make up of the road surface, the quality of the road surface, the state of your tires, what speed you're travelling and a myriad of other things. I'm not quite sure what the point is you're trying to make other perhaps some tires are perhaps noisier than others, tell me something new.
