Road/tire noise.

[Waynerm002]

I’ve never tried the Yokohama brand tires, i have seen them compared on videos on tire rack site and they seem to be decent tires however, lately in life I have been going to one tire for all season route and their winter performance seems ok but I ended up going with the General G-MAX AS-05. Give those a shot and let us know how they perform. The review from owners are pretty good so unless you drive real aggressive all the time the Advan AS should serve you well.

I’m pretty aggressive but not crazily so

Anyone tried the dws 06 235 45 r18 xl?
Know it’s 10 mm wider but should still fit right ? Seem pretty well regarded
Also can you put 235s on if other brands to hopefully avoid curb rash ?

Also for those who are replacing bridgeestones ... what are u getting for selling them

Dont they have to be XL Load rated? didnt see those with XL load ratings in this size

 

[Waynerm002]

They come with the XL version for the Stinger. You can do a look up for tires for the Stinger on TireRack.

Just a frustration venting update.

Haven’t learned much recently. Issue seems to change on a whim - temperature, tire pressure, etc. in the rain at 70 degrees and lowered tire pressure (33/36 instead of 36/39), my previous issues with a “buffeting” like sensation in the cabin returned for a bit. Since this is a new set of tires, I’m sure it’s something else.

All that said, I just haven’t been able to make the time to get it into the dealer again. Crazy hours at work & no loaner means no dice for now. I also dont have much faith in a resolution at this point either, specifically because of how varied the behavior is.

Again, just frustration venting, please ignore .

Does this seem to happen in the first few miles of driving after being parked? Could this be related to flat spots?

I though that was the case with the first/stock set of tires. So I bought a completely new set of Michelins. It's possible that with the slightly lowered tire Pressure the Michelins were also exhibiting the same behavior due to flat spots, but its also not the only issue I've encountered (noises and vibrations beyond just the first few miles).

It has been known for electronic noise cancellation systems in cars to cause a 'buffeting' effect. I could imagine the system trying to nullify low-frequency road-noise rumble, which in a car will be complex with period wavelengths spanning the interior dimensions, i.e. diagonally, side-to-side and front-to-back, meaning that at certain low frequencies the ambient rumble will be out-of-phase in different parts of the car's interior, and very difficult to counter accurately with electronics. The net effect could be the noise canceling system actually adding to the amplitude of some of the low-frequency ambient noise, resulting in 'buffeting' and could even be localized depending on where one was sitting.

I've no idea if this might be the case in the Stinger, but perhaps it might be worth experimenting by disconnecting the car's speakers temporarily. I'd start with the subwoofers first, and see if that makes a difference, then the rest.

Others have theorized that it might be from the noise cancelling as well. I've put off any type of testing related to this based on what it means: since I don't think there is a way to turn the system off, if I ever did narrow the problem down to noise cancellation, I would be faced with either removal of at least some cabin speakers or dealing with the issue - neither scenario would make riding out the rest of my lease any easier. As a result I've focused on trying to identify/diagnose what I can with the tires/wheels/drivetrain.

Sure thing, I would have done the same - if it did come down to the noise cancellation, I'd be looking for the easiest solution, whatever that may be. It's possible Kia's engineers are aware of the issue and have remediated it in the MY19 cars, or that the owner community will get creative about finding ways to mitigate the problem. It could be as simple as locating the sensing microphones and electrically isolating them. I've yet to order a car (been waiting for MY19), but any 'buffeting' would drive me around the bend (and into a lamppost).

Keep the tire pressure as close to stock as possible, the different pressure seem to make them produce a different tone. I’ve been experiencing something similar with some new tires I installed on my Optima Hybrid where the tire noise can be a bit louder 3 psi below stock. While the car ride is a bit more comfortable (I did also install lowering springs) the noise isn’t. At stock pressure, it handles better and the noise is less but as the temps rise the ride can get a bit firm. At 1 psi below it feels more like the perfect comfort for bumps and the noise the tire generates seems a bit better but the handling isn’t as crisp. Hope you can get this sorted so you can get back to enjoying your car.

@patriotsfan82 did you ever find a fix to your problem? What you are describing is exactly the same thing which is happening to me after replacing the Michelin summers with Conti DWS 06 all seasons. I've already had them rebalanced by the dealership and they told me it was normal as the tires break in. Well it's been a thousand miles now and the problem hasn't gotten one iota better. I think I'm actually going to take the thing to my old Honda dealer and have them do a balance since I know and trust those guys.. In another thread a guy mentioned he finally took his car to another shop other than Kia and his weights were all off. They balanced properly and the vibration stopped entirely.

 

[Waynerm002]

I have the buffeting noise with both the Michelin's and the Nitto Motivo's. The noise comes in around 35 -44 mph but is really present at 38 mph in my car. I don't think this is a noise cancellation thing, I don't think it was ever confirmed that this is actually in the Stinger. One morning when I was coming down with a cold, my ears hurt a lot as I had to drive at low speeds for 30+ miles as I believe this is an air pressure thing but don't know what is causing it. I'm wondering if anybody has had a dealer that has been able to replicate this issue. They tell me it is tire noise but I know it isn't.

 

[Onno P]

Guys, could the reason be the mounting of the tyres?
Are they directional and mounted the wrong way around maybe?

My Continentals are directional and I can confirm that they are all mounted properly

 

[Waynerm002]

Nah, that would mean both KIA and the other installer, and me are not paying attention to how they are mounted.

 

[Hojae84]

I am starting to think it's a differential howl
I went from all seasons to ps4. A little quieter but I'm starting to think it's less tires and more differential howl

 

[MikeysGT]

The reason I'm lead to believe it's a balancing issue is because of the speeds at which it is most noticeable. Steering wheel vibration kicks in at about 45mph then becomes more predominant at 70+ and only gets worse. But I could be wrong

Your issue with vibes at high speeds only is a tire balancing issue.
I guess I'm more targeting a wierd sound I have always gotten randomly that sounds like its comi g from tires. I'm just thinking out aloud.

No worries. It's not very bad either, but it's also all the way around as I can feel it in the steering and my legs both. I can't be lead to believe it's just the way things are with the tire because no tire should be vibrating if it's balanced correctly. I do get some road noise, but it's nothing out of the ordinary that I haven't heard before. The Michelin summers weren't the quietest, but they were a smooth ride. No vibration.
