The foam in one of the tires of our new '21 Model Y became dislodged inside the tire and we had to have it replaced. At first I thought the wheel had become unbalanced, but then figured out/realized that it was the foam bunching up inside the tire while driving.
When we purchased our 2018 MS 100D it came with foam lined tires. The car had a rough ride but maybe the tires were quite. I would not know as my hearing is bad but my butt let me know the ride was rough. After twenty seven thousand miles I replaced the rough riding Continental foam lined tires with Pirelli smooth riding tires. How do I know the Pirelli tires are smooth riding? My old butt let me know. I still can't hear that well but my butt feels better on my Pirelli tires. I did not spend more money on foam so I am a bit richer.
From a test by Car and Driver in 2016, it wasn't the decibel range that changed, it was the frequency of the noise that made the difference. For this reason some people perceive it as quieter because it changes to a tone that sounds "better/quieter" to them. Others might not be bothered by any frequency in the sound spectrum and therefore don't perceive a difference.
people dont like high picth noise an s class is precieve to be alot quiter then say a camary even thou there only maybe 5db in it on testing but its frequency that is engineered out
@@Nordic_Mechanic This is true but the sound is being generated within the hollow cavity of the tire/rim combination. No matter where you put the foam, it will most likely absorb some of the sound.
Honda has done this. It is very difficult to implement because the centrifugal force when the wheel is spinning wants to separate anything that is attached to the inner part of the wheel.
Some people say their new tires are just as quite as old ones with foam. Don't forget that the tire get louder with age; older the tire is, the louder it will be. So make sure you are comparing apples to apples; new tires with foam vs new tires without foam.
Goodyear Eagle Touring SoundComfort tires made a big difference over my Impala’s 20” Bridgestone Potenza’s. I ditched the Bridgestone Potenza’s with less than 20K miles on them. The difference was significant. I’m happy!
Great video! You mentioned that the tires came standard on Tesla. Is that the noise reduction tire or the one without the foam? Also what's the identifier on tires that indicates they are noise reducing or foam filled?
I didn’t notice any difference in regular real driving on my commute when I went from my stock tires with foam on my model 3 to the new tires I bought for it that didn’t have foam. Real meaning HVAC is normally on (and if not the window is open), and the radio is almost always on, either listening to books or music. So, unless you drive with absolutely nothing on in the car for long stretches, I wouldn’t get bent out of shape to get a tire with foam in it, especially if they cost more. Clearly here they used th same tire with and without foam. But, a different tire may have a quieter characteristic than this tire.
My question now is how big of a difference is the foam lined low resistance tire with a wheel that has an acoustic resonator built into the wheels to accomplish the same thing, such as Lexus, Acura/ Honda, and Genesis? If read tests claiming no reduction being measured across the audio spectrum. It seems like the quietest tires on the market such as the pirelli cinturato p7 plus 2 and bridgestone quiettrack don't bother with foam! Only Goodyear and continental waste their time? The best from Michelin don't bother either. Its more down to tread pattern, construction, and material compound than just adding a piece of foam to make a quiet tire. A skinnier tire contact patch and thicker sidewall for NVH reduction is worth more than a piece of closed cell foam in a tire bandaid.
Did anyone else find the bottles of water completely distracting? This video, whilst informative, was pretty boring. Would have been better to throw the rear passengers out and put some decibel meters in their place, and shorten the video by 2/3
I don't want to hear a spokesman talk about their product I want to hear a sound comparison. This video is formatted terribly, it's hard to find that actual comparison. Downvoted.
very interesting... i would love to buy that tire! Guess tread on a tire is a big factor too? Perhaps they could put the same foam into deep carbon rims - cycling
Maybe I expected too much here... But I could not hear any difference anywhere. You guys talked a lot. Way too much. Not to mention you had this lengthy discussion inside the car, although it could have been done outside. So anyway - is there any consensus? Any empirical data of noise levels inside and outside?
Video is way too long and got boring fast. Why are you four people in the car in the middle of a pandemic btw? The guys in the back contributed nothing.
They say in the video, the average improvement is 4db in the cavity frequency range, but subjective testing is also required, because that's how the customer determines whether a noise is bearable or not.
Boy he's got a dull boring voice. I'd fall asleep if he was a professor at a college or university. He needs to speak more clearer and a tad bit louder.
Oh no! Not tire noise! First world problems much? How about addressing the particulates in the room? Only partly kidding. This is good stuff but the additional particulates from heavier vehicles is one criticism that has been leveled against EVs (though the same study didn't even acknowledge the vastly reduced particulate load from the vastly reduced need to use friction brakes in EVs).

And the first 11 minutes of ignorant blabbering like he never heard tire noise in his life, well he did just doesn't have a clue
I've never been so bored watching a video in my entire life
20:45 with foam
Some might say if the goodyear rep stopped talking during the tests....everyone could hear if there was a difference.
The foam in one of the tires of our new '21 Model Y became dislodged inside the tire and we had to have it replaced. At first I thought the wheel had become unbalanced, but then figured out/realized that it was the foam bunching up inside the tire while driving.
Happened to me on my three. The tire shop thought I was crazy because I kept bringing it back to be rebalanced.
In my experience it doesn’t make a difference. In fact, the tires I replaced them with is quieter and they’re not acoustic tires. So…

I would love for a way to add foam (or whatever noise reduction feature) to the barrel of the wheel, and not pay a premium for every tire.
You can diy. Buy fire polyurethane foam and spray glue that don't dry. Make sure to do wheel balance afterward
The rim doesnt vibrate to create noise, the tire does.
@@Nordic_Mechanic This is true but the sound is being generated within the hollow cavity of the tire/rim combination. No matter where you put the foam, it will most likely absorb some of the sound.
Honda has done this. It is very difficult to implement because the centrifugal force when the wheel is spinning wants to separate anything that is attached to the inner part of the wheel.
Good topic, need results displayed or something. Very hard to hear understand
16:30 no foam
Great testing Kyle!
Wow silver is the perfect color for a Tesla, and especially that Model S! What a shame they discontinued silver.
Does the colour influence the sound of tires?
How do tire sealants work with foam inside? Is the foam porous enough for sealant to work? Thanks.
It's a valid and common question, but no ones answer it.
Can anyone explain?
Can this be applied to other tires?
I have a bmw i3 and I’m stuck with one brand of tires
That's a very niche tire size and type

I believe the Tesla Only tyres have the "TO" identifier on them.
I wonder if we could add foam aftermarket.
I can't find who, but a youtuber tried to DIY this and it was problematic to do it right. I think the issue was balancing.
Probably closed cell foam band by the looks of it.
I have seen it before

Does the foam affect heat dissipation?
Due to the porosity of foam it can’t hold much heat so it shouldn’t affect it at all.
Great video, I could hear everything he said. Can't wait for more videos
This video could have been done in 2 minutes ffs
They go over a lot of information about tires. It made the video better by explaining more in depth.
Dyno mode is available again? I thought they shut that down.
(just starting the video, don't know if it's addressed)
It’s on engineering, non-public software

they didnt show any noise record with noise reduction tyre anf without... how i can see the result? just talking and explaining the theory.

Insane amount of mid-roll ads in this video. Unwatchable.
Yes! youtube is become annoying. and they want me to pay! newsflash, annoyance does not lead to subsciptions
@@danielmitchel1189 that’s not UA-cam, video creators control how many adds and what kind of layout
found it too long and muffled audio made it hard to watch

I could hear the difference in the two tires
It's stops ringing in the tyres when you hit a bump
23 minutes I’ll never get back just to find out the answer is yes.
Very interesting,this guy must be going crazy on a ruff surface!
I like the good year guy driving with the blue mask his voice sounds like ramon from everybody loves raymond
Great job Joshy!! ❤️
Seems this video was made with a foam filled mic also...
Is it ok to patch tires with foam? I know they usually just cut it out of the way.
Yes, they just cut out the foam in the area being patched.
I have personally patched one with the foam. It was fine after I trimmed back the foam then glued back afterwards.
very interesting... i would love to buy that tire! Guess tread on a tire is a big factor too? Perhaps they could put the same foam into deep carbon rims - cycling
Drew, I feel your pain, I could barely hear the guy too lol 😜
If you guys ever need a UK presenter let me know. I am on a mission to get all drivers, especially disabled ones, like myself, to transfer to EVs
Seven adverts in a 23 minute video. Bit much no?
Funny, I was able to find the super secret location.

Well, we can add another video to the long list of "videos about tire noise without a single objective sound measurement". 🤦🏻♂️
They say in the video, the average improvement is 4db in the cavity frequency range, but subjective testing is also required, because that's how the customer determines whether a noise is bearable or not.
Frequency sounds (pardon the pun) to be more important than noise
Masks during interview. Lovely
And what happens when you get a flat? Gotta buy new tire =profit
only if the damage is outside of the RMA's guidelines for repairable areas of the tire.
Two step procedure to make your Tesla quieter:
1) Sell your Tesla.
2) Buy any other EV, in same price range.
Or one of several in a lower price range 🤣
Totally agree. I want an ev as the ultimate isolation / relaxation car, which Tesla’s aren’t.
Basically any luxury car is quieter than Tesla lol Tesla isn't luxury.
can barely hear them wearing masks
This guy is so annoying
Are you referring to the host?
Total waste of time, without at least a decibel meter there's no way to objectively measure any difference.
Boy he's got a dull boring voice. I'd fall asleep if he was a professor at a college or university. He needs to speak more clearer and a tad bit louder.

Blablabla. Too much talking, Zero measurements. Don't hear the difference.
