When I got the RS I almost directly switched to 17" winter tyres, so never really had a chance to listen to the noise from the 18" Bridgestone Potenza S001 tyres. But since switching back to summer tyres I am getting really annoyed by the road noise. Also comparing it with my Fabia mk3 17", the Fabia is a lot quieter, which I find strange as Octavia sits on a more expensive platform. 

 

Anyways, I have tried to soundproof the boot (just in the spare wheel area though) but it is still a very noisy cabin, to an extend that I am getting really annoyed every time I'm driving the car.

 

Anyone else has the same experience and what have you done about it?

 

I can't say this is the same noise as the 'booming' sounds, discussed in another thread, it is more of road noise or a rumbling noise which I think is coming from the tyres.

Checking the noise rating for the Bridgestone tyres shows they are a very noisy tyre, so that may contribute to the road noise

It is what it is.

Not so sure that your Octavia vRS sits on a more expensive platform, it sits on a MQB platform the same as the cheapest Octavia do and which the VWG came up with to save on build costs and still make profits, common to Leon, Golf or other models at lower prices than your vRS,

you just paid more, that is not the same as a more expensive platform.

The Octavia doesn't have the best sound-proofing in the world but on my car I would say it is acceptable given the price.

The roads are much smoother & rarely with potholes here in Switzerland though so that does minimise the road noise effect.

 

I can't say I really noticed much difference with road noise between the original 18" Conti CS2 and 17" Conti WC2 tyres.

My main niggle is the wind noise from the wing mirrors.

 

When you had your 17" winter tyres (running in the warmer dry weather) was the road noise better or did you have the same problem?

Is your expectation that the summer tyres will be much quieter than the winter tyres or are they really more noisy?

Well as you have identified the problem as a combination of larger wheels and the tyres, the only thing you can do is A; get quieter 18" tyres for the summer wheels, or B get quieter 17" tyres and use on new or existing wheels.

I thought the Potenza's were meant to be reasonable for noise ? Certainly the Conti's on mine are known to not be that quiet, but it only manifests itself badly on certain surfaces.

I was hoping the Bridgestones would be a bit better as they look to be what is coming through on current vRS's atm.

You are misunderstanding me, I was comparing the MQB platform with the PQ25/PQ26 the Fabia Mk3 sits on.

Right, I would say me expectations are that summer tyres are quieter than winter tyres. But then there is the difference that my summer tyres are 18" and winter tyres are 17". The winter tyres are Contintental TS850. I haven't checked the figures and compared between the tyres though. I agree that Bridgestone is not the most quiet so the best solution might just be to buy quieter tyres...though that wont happen until these Bridgestones are worn out. Thanks for all suggestions and feedback

This was my understanding too before, that Bridgestone was an OK and quiet tyre. The Fabia also came with Bridgestone tyres, so I'm assuming this is what all Skodas are being shipped with nowadays

Re post #6,

Skoda are often saying about the All New 2015 Skoda Fabia that the platform has Elements of the MQB Platform, components of the MQB Platform and such spin.   It has Suspension and engine mounts,  it had no need for new type approval.

 

So the 2015 might be a cheaper car, 2 class sizes down, but since the platform has been around for a while then Adapted and had Elements of and Components of and such stuff done,

Does it make it lesser than the MQB really, or just actually shorter and lighter.

 

The 3rd Generation 2015 Fabia is a bit noisy on some tyres on 17" wheels and i have driven Petrol & Diesel ones with DSG,

they have pretty poor sound deadening IMO, and a very annoying diesel engine noise.

and i have driven Mk3 Octavias petrol & diesels on 17 & 18" Rims / Tyres,  these are a treat compared to a 2015 Fabia.

 

re tyres.

Any of the brands Skoda fit at the factory might be on cars that arrive in the UK,

Dunlop, Bridgestone, Continental even Kumho & on some Skoda models that suffer Pulling to the left,

Skoda approve fitting Pirelli and then blame the tyres they fitted at the Factory, and which they fit to thousands or

millions of cars.

When I got my FR it came with Conti Sport Contacts like a lot of earlier VRS Octavias did - same size 225/40/18. Once they were shot (didn't take long) I replaced them with Goodyear Efficient Grip Performace all round. The difference was night and day - similar grip levels (better than the Contis in the wet) but so much quieter, longer lasting and better riding. I didn't notice any efficiency gains that they advertise mind. I'm expecting the VRS I have on order to come with Bridgestones but when they need replacing I will be definitely going for the Goodyears again.

I have heard great reviews of Goodyear as well so these are what i have in mind changing to when the time comes. I am thibking of sound proofing the rear wheel arches as well but cant figure out how to remove the trim so might just have to call a garage to get help. The same goes for the door trims due to their airbags.

I have posted on here before about the amount of road noise I experience in my vRS.

There seems to be no definitive answer although i suspect some shortcuts in the soundproofing department.

The OE tyres on mine were Conti 2s the same as many of you guys and I found them to be very susceptible to road surfaces when it came to noise transmitted through the car.

I now have my new wheels which I have fitted with Goodyear F1s and although far from cured, I find there is less noise with them.

I have just today covered the bare metal in the boot and under the rear seat with SilentCoat and it has made a significant difference to the noise level. I did not do the wheel arches as I felt that the larger floorpan area would have contributed more to the noise. I was expecting to have to convince myself that it made a difference but was pleasantly surprised.

What is this silent coat stuff, sounds like I could do with a few litres!

Edit, not litres, sheets...had no idea...

You've just spent £30K then have to spend £100 to fix it.

My situation is better, I spent £15k on the car and only £45 on the SilentCoat. It's not a case of having to anyway, noise in a car is a subjective matter. I chose to gamble that it would work and I am very pleased with the results. 

Is it just the boot floor and under rear bench you guys have applied the silent coat?

Chris29, I got the 20 sheet pack and totally covered the boot floor, including the spare wheel well, and under the rear seat squab. It was very easy to fit, it is quite flexible, very sticky, I used a wallpaper seam roller to bed it down. I did consider doing the wheel arches but, as I said earlier, the floorpan is a much bigger drum and should respond to the damping with a greater effect. I was also considering putting a sound blocker layer under the carpet but I do not think that is necessary now. 

Thanks Paulius, see what the vRS is like and I may just do the same

Is it just the boot floor and under rear bench you guys have applied the silent coat?

So far I have put silent coat on boot floor, under the back seat, tailgate and under the carpet in the back. I plan to continue to do under the carpet in the front, and might also do the rear wheel arches if I manage to remove the trim. I don't think I will do the doors, but you never know.

Which one did you get? the standard vibro damping pack?

I've been using the vibro damping mats as base, then adding silent coat noise isolator or where applicable, a sound insulation blanket (e.g. under the floor)

Did you use the 2mm or 4mm version?
