Hi Guys,

I noticed with my new 2010 Octavia that i have allot of road noise in the cabin, it seems like its coming from the tires !!!

In my country there is nice and bad streets yes but i didn't have this problem in my old skoda flecia , or toyota !! or this is something in the Octavia ????????

the Octavia came with Continental 16' tires and i got the car only from one month ago.

I don't know what to do? some one advised me to change the air in the tires into Nitrogen !!! Other said change the tires !! but they still new and it seem a good company, and even so how can i know if i got me new tire i wont hear the noise ?

I think if you search the forum you will find a lot of discussion on road noise, which does seem not to be one of the Octavia's strongest points. However many have commented that tyre choice makes a big difference. I took delivery of my new Elegance Estate yesterday and it has 16 inch wheels with Good Year tyres and it is noticeably quieter than the Elegance hatch that I test drove which was on Bridgestones.

Plus I think any brand new tyre is noisier than one that has had some miles worth of use to get rid of the outer (hard?) layer that is something to do with the manufactung process - I certainly noticed a difference with mine after the first few weeks that wasn't just me getting used to the noise! But also I suspect this is one of the areas where skoda cut some non-essential corners to make the car cheaper over the golf and so the noise reduction matterials on wheel arches and the floor of the cabin are no doubt thinner and less efficient than the equivlent golf model (and having experienced a golf not long before getting the octiavia it is def the case that road noise is higher in the octy)...

thanks guys , i did search the forum before i post, but i didn't see any fulfilling answers.

i have some options now

1- wait till the tire become old !

2- change the new tires to another brand !

3- accept the fact that the cabin floor of the octavia is not doing a good isolation, so do nothing !

:S

Or option 3 could read ...

3- install some sound deadening material under the carpet in the following areas;

under the rear seat, under the boot carpet & in the spare wheel well.

I was in a Passat at work yesterday & it was definitely quieter,

but not to the extent that I've actually bothered fitting any sound deadening to my Octavia.

Although I have Avon tyres, which I found to quiter than Continentals.

thanks allot for that option , although i don't know where i can find that deadening material here in my country , but i will try to find it if that noise didn't improve with time :|

People on here have experimented with carpet underlay, or more expensive sound insulation materials.

You may have seen that speakers are often covered in a type of carpet, that's the sort of thing.

In fact have a look here for some suggestions ...

Sound absorbing

If you do go up the additonal sound absorbancy route, please make sure that the products used are suitable for a car environment. It is not uncommon for highly flammable adhesives to be employed in other applications which may at first glance look suitable..............

great stuff and sound promising too thanx

but it seem installing the sound deadening mat is not something i can do by myself under the boot , from the videos it looks easy to install it my self in the trunk and may be under the back seats .. but other than that i think it need pro dont u think ?

New Octavia is famous for its road noise, which unfortunately comes from a bad suspension design. The same problems are on Audi A3, VW Golf V (same suspension in those as well). Passat has a more sophisticated suspension and that is why it feels quieter (the same is Audi A4). So even if you install sound insulation don't expect miracles regarding road noise issues, you will not eliminate it. There are a lot of topics on that in Russian forums (their asphalt quality is poor). People done full insulation with professional noise insulation products and it had almost no effect on a road noise.

I saw this sound deadening on ebay and it looks cheap and chearful. I thought about sticking a bit under the rear bench. Not sure its suitable for placement in the boot and around the spare wheel though?

Just had Kuhmo Ecsta's fitted to my Scout and the road noise has quietened down, however wind noise from the rear of the cabin is more noticeable.

Basically you want to apply matting to certain areas to reduce resonance in the panels.

You won't kill all the noise, but it will reduce the most annoying parts of the spectrum.

Nitrogen-filled tyres are so much snake oil, except for competition cars, where they get a more predictable change of pressure with temperature. Save your money on that one.

It could be the tyre type, but without knowing what you're comparing with what there's no way to be sure either way on that one.

i don't want to believe its something wrong in the suspension :S cause in good asfalt i don't feel that noise

but cause the good asfalt is not always present in our roads here and there is allot of grainy kind which produce noise , but with the octavia it feels like the sound got inhanced or magnified :wonder:

the tyre type is Continental , is it harsh on asfalt ??

do u think changing the air into Nitorgen will really decrease that noise on the grainy asfalt ? if so i would run from tomorrow to change it

what about the tyre it self ??? can i talk with my dealer to change it ?? but on what basis i would tell him ?? he could simply say there is nothing wrong in the tyre

or may be i should check for the date of the tyre may be something wrong in it ... i dont know :'(

Sound deadening material, on the spare wheel well sides and base, the boot floor and under the rear seat bench will remove the worst of it.

thats it then ? that sure need a pro to remove the seats to install it in the floor right ?

why skoda didnt fix that ..how come i buy such a luxurious car to suffer that nose :S

Could be the tyres,here at Work we had an Octavia and a Roomster with similar noises,it was a failed wheel bearing noise....Try and fit even a set of second hand tyres or borrow a set from someone you might know to see if the road noise disappears.That's what we did to solve the problem,The Octacvia had Continental's and the roomster had Bridgestone's.We fitted barum's on the Octy and Firestone on the Roomster .... Pointless doing the same make.

nice idea i will arrange with the dealer to fit me other tires for trial and see what happen

You can DIY the boot floor and since the rear seats fold you can get some under this too.

No need to pay anybody. A lot of the noise comes from the fact that noisy tyres on a poor road surface cause sound at a frequency where the bodywork seems to act as a drum.

If you're around my way you could always try this at little outlay to see if it does what you want:

EDIT: Scrub that as you're in egypt, but yes, try something like dynamat or another noise damping product on the bare metal areas of the car.

don't I need to remove the seats and the carpets to be able to cover the boot floor ? or u mean just under my feet ???

if so then it can be done by me

i don't know how to get such a sound deadening material here in Egypt , I'm thinking either tell one of my friends in the UK to bring me with him, or ask an engineer friend if what they use as sound deadening in the construction can work in the car !!!! as this construction sound deadening material i know present here.

today i was speeding on the high way and i noticed beside the road noise that there is a wind noise when i run above 110 km/h coming from the windows or the doors i don't know , i think also there is wind sound from the roof hatch.

:S :S :S

Well as has been mentioned, thin carpet (or laminate floor) underlay could be used, or perhaps try and obtain some felt material and use that cut to size under your existing mats etc (felt is used for lots of things so widely available), a few milimeters thick would be enough to make a difference (it would essentially be an extra carpet layer and would reduce noise in the same way as thicker carpets reduce noise between floors in apartments etc.

On the subject of wind noise, yes you get that too above certain speeds (its the wing-mirrors), but nothing you can do about it I'm afraid...

mmm isn't the car's boot materials r made from felt ? or the idea is to have more thinkness of it ? if that will help it would be a nice idea :yes:

i red on the Wiki how the felt is a damping material used in automobile and music industry.

why they don't normally advise with the felt material right away , or its not as effective as the other sound absorband deadening materials ?

My boot and underseat had not felt in it at all, so I applied dynamat to the metalwork in slect places and then placed a layer of felt under that.

The difference has been huge.
