Has anyone else noticed a lot of road noise from the new i30? My car has the Hankook Ventus Prime 2 in 16 inch guise fitted and at motorway speeds I am finding it pretty intrusive.
:MeToo:
Those original Hankooks combined with our rough pavements makes the noise almost deafening! :wacko: However, new tyres aren't free so I have to live with it until they are worn out.

Do you mean 'Contact' , not 'Comfort'? I can't find a tyre called comfort?
No, it's Continental (german) and the model range is Conti Comfort Contact CC5. I doubt you woud find any of the old 2 range these days.

Mine are Hankook also (with some Eco branding and flower design on the side wall). Can be quite harsh and but after 22,000kms have found them very hard wearing with virtually no wear so far... unfortunately. I also want to get rid of mine for a softer tyre wall and quieter ride. A few years ago I bought bridgestone Turanza GR90 for another car and they were great. Not sure if GR90 is still available though.

MC5 and CC5 are the noiseless types to be looking at :link: Continental Tyres -New: ContiMaxContact? MC5 (http://www.continental-tyres.com.my/www/tyres_my_en/themes/pcar/contimaxcontact_5.html)
Looks like they are either not available in the UK or are branded differently here as this is the Conti range available:
:link: Continental Tyres -ContiPremiumContact (http://www.continental-tyres.co.uk/www/tyres_uk_en/themes/car-tyres/standard-car-tyres/contipremiumcontact/)
From what I have read elsewhere owners seem to rate the Premium Contact 2 so I wonder if they are the equivalent of the Comfort Contact? The Max contact are not available here either.
I have an option to buy Michelin HP Primacy 3's but have not read anyone having tried them.

Really appreciate you taking the time to look atthis with me - great help.
The problem is, if you go to that site (or any other) and enter my tyre size (205/55 R16 H) then it sure does fire up all the Contis but still doesn't list the ContiSilent. It has the Premium Contact, Sport Contact and Eco Contact. A quick look at the Product page for the ContiSilent appears to suggest they only do it in certain sizes. I called a local dealer and they have never heard of them so make of that what you will......

Continental ContiPremiumContact 2 205/55R16
I read on one site they are meant to be used in summer, and Continental does not recommend that people use it where there may be ice or snow. Luckily ZA isn't too cold and the coldest we get here is maybe 4 or 5 degrees Celsius.

The Continental ContiPremiumContact 2 is a tire designed for a superior appearance. The ContiPremiumContact 2 comes as original equipment on luxurious sedans and similar vehicles. This is a summer tire and though it handles well in wet and dry conditions, it is not made for driving in icy or snowy environments.

I changed the Hankook tyres on my 2013 i30 tourer for Dunlop Sport BluResponse and by using a professional decibel meter I established that the cabin noise was reduced by an average of 2 dB on rough tarmac which was disappointing. On my previous i30 hatch I changed to Continental Premium Contact 2 tyres and the noise reduction averaged 3 to 4 dB. Neither of these improvements would really be noticed by people with normal hearing - but I suffer from hearing loss and every little helps.
If your hearing is OK and you can hold a conversation with passengers in the car - it is not worth spending on new tyres until such time as the present ones are worn out. My wife has good hearing and never really noticed the difference that my tyre changes made.

Last year whilst on holiday in Portugal I hired a Citroen C4 Picasso and was impressed with how quiet it was - it was shod with Michelin tyres.
Recently one of my friends gave me a lift in his C4 Picasso, also shod with Michelin tyres and cabin noise on the M6 motorway was dreadful - much worse than my Venga and my previous i30'son Continental tyres.
I have concluded that most of the main roads and motorways in Portugal have been resurfaced (using generous E.U grants) with the low noise tarmac now being used on our motorways - and that was why the C4 in Portugal seemed quiet.

So. It's going. I should have trusted my guy instinct in the first place that 'if it's cheap, it's cheap for a reason'. The car has come a long way but it's areas like this where brands like Hyundai and Kia (there will be others) save money.
Lesson learned - if I want the creature comforts I will have to pay for them. Back to VW or Volvo for me.
Thanks to all for the replies.
Post by: AlanHo on July 02, 2014, 13:03:33
The Golf was slightly better on some surfaces but worse on others. Overall it was a draw.
If cabin noise is a major concern - road test various models and check the cabin noise scientifically
If you have a smartphone you can download a Noise Meter app. There is no need to calibrate it against a proper decibel meter because it will be accurate and consistent enough for comparing one car with another. I took my wife with me when we went road testing cars - she sat in the front passenger seat with the decibel meter and noted down noise readings whilst a gobsmacked salesman sat in the back muttering he had never ever had a customer do this before. It is important to take each car over the same route for consistency.
Post by: Paulq on July 02, 2014, 13:12:23
Since this problem arose I have 'test driven' 3 more i30's as you have suggested - all the same. The issue is with the design and the soundproofing. A quick Google search will tell you I am not alone....
Post by: Doggie 1 on July 02, 2014, 13:19:54
I have now had the car 2 weeks and, to be honest, I utterly hate it and principally because of this issue but also niggly things like a ridiculous steering pull that needs a proper alignment - at my cost of course. I had 2 more people in it for the first time on Saturday and, even at normal speeds on Motorways, we simply could not hold a conversation. My other half has flatly refused to go on holiday in it in September.
So. It's going. I should have trusted my guy instinct in the first place that 'if it's cheap, it's cheap for a reason'. The car has come a long way but it's areas like this where brands like Hyundai and Kia (there will be others) save money.

Refreshh my memory.
Which i30 do you have?
Road noise is one issue.
The steering "pull" you speak of sounds like it could be the known EPS issue.
If it is, it's a warranty item.
Don't be too hasty because the vast majority of i30 owners can't be wrong.
Post by: Paulq on July 02, 2014, 13:22:27
It's a shame, otherwise the car is good but it's simply a ball ache to drive it at anything above 40 on anything other than glass smooth tarmac and we ain't got much of that in these parts :)
Post by: Doggie 1 on July 02, 2014, 13:27:08
Those two issues are my only gripes, but they're pretty minor.
The EPS will be fixed under warranty and the road noise can be reduced by careful choice of tyres.
I think it is something Hyundai will address in future models because I'm sure they monitor these forums.
Other than that, I'm very happy with mine - just had its 75,000 km service today and still nice to drive. :)
Post by: musicrab on July 06, 2014, 23:23:44
For some reason the noise didn't show up on the test drive but 2 minutes down the road after purchase it was very bad. Almost turned round and took it back. But am now getting used to it.
Have just done an 800mile trip and when on newly tarmacked black/smooth roads (mainly motorways) its fine. But anything else and the noise is really bad. My test drive must have been on smooth tarmac.
Why's it this bad? I can only imagine that Hyundai testing with Hancook's must have been on nice new smooth black tarmac.
Apart from that, car seems fine. (Bought because feels bigger than a Ford Focus; I don't know how Ford made the back seats and boot feel so small in the new Focus).

Personally, I think that the i30 could, and should, be quieter.
But I can't agree that the car is poor.
It is a very well designed and executed car with mostly positive attributes.
All cars, yes, all cars have faults. IMO the faults on the i30 are minor, given the intended purpose the car was originally designed for.
I'm on my second i30 (and I have owned a lot of cars), and as I've said elsewhere on the forum, so many people can't all be wrong.
However, good luck with whatever you replace it with. I hope it works out for you.

It's not just Hyundai that suffer with road noise. Do a search and you'll see Mazda 3's suffer the same issue. Even the new Corolla isn't immune with plenty of complaints out there. :undecided:The problem is when you come from a quiet car to a noisy car - you notice! My Vauxhall saloon is 15years old and is noticeably quieter than my 6month old I30. (I'm specifically talking about tyre noise here).
Google just about any other small car and I'm sure you'll find similar complaints.... :undecided:
And, is the I30 really a "small" car?
Post by: rustynutz on July 07, 2014, 12:47:41
While engines have got more economical, much of this has been cancelled out due to the extra weight needing to be lugged around.
The solution has been to cut back on sound deadening and to make use of lighter materials. These obviously don't deaden the road noise as well.
And as for the i30 being a small car? Well, it certainly is here in Australia...there's basically "Light", which is your Suzuki Alto size cars, "Small", which covers the i30, Corolla, Mazda 3 etc, "Medium" which is your Camry's & Mazda 6's etc & then "Large" which cover Commodore & Falcon etc etc......

"I can confirm that we have not had any similar reports from other i30 owners, however any comments on road noise are usually generated by a significant difference between the i30 and whatever car the customer had previously, and what tyres were fitted to it. It is true that different makes and models of tyres will generate noise to a widely varying degree due to the friction between the tyre and the road surface.
I can only recommend contacting your local Hyundai service centre to ask them if they can check your car to see if there are any defects that could be causing an excessive noise. If they are unable to find anything untoward, then the noise you are experiencing will be a characteristic of the tyre.
Yours sincerely

The i30 is quiet on this road, and you can actually hear the engine more than anything else. In the clip it sounds like there is a bit of wind noise, but there actually isn't :)
I didn't get much as there were a bunch of bikes on their way past and you can hear the first one going past near the end of the video, just before I stopped filming.
I hope someone finds this useful as I have seen a lot of posts whereby people are saying the i30's are a tad noisy WRT road noise.

Slightly worried that I can feel a bit of road through the clutch (when in use) but I think I'm just a bit paranoid:-) Car is fine other than that.

Hopefully I still have some time off before I have to consider replacements!

So a bit of road noise seems like a fair trade off for extra safety.

It seems to me the coarse surface would give much better grip in wet or icy conditions.

I prefer peace and quiet.

The people in cars coming towards you on a wet and windy road might beg to differ.It seems to me the coarse surface would give much better grip in wet or icy conditions.

IMHO, as drivers we have a responsibility to ensure our vehicle is in the best possible condition to provide a safe environment for all road users.

What has our vehicle's condition got to do with the road surface?
Also do you have any evidence that the road surfaces which are basically stones protruding from tar are better for grip than a smoother to the eye road surface?

It was in response to your comment about preferring quiet, which suggested you were prepared to sacrifice safety ffor quietnes.
As for road surfaces, road authorities the world over spend millions researching such stuff. As do tyre manufacturers and road safety authorities.
Their findings are pretty much public records and support what I'm suggesting.
As does common sense.

Can you show me this research? Why are roads in other countries quieter? With a less coarse road surface you are actually going to get more contact between the road and the tyre. Your point doesnt explain why some roads in UK are nice and quiet and others are not.

With a less coarse road surface you are actually going to get more contact between the road and the tyre.Road surfaces depend on many factors, high or low traffic usage - pitch and angle - speed - rain - snow - ice -heat, all these can decide the types of surface to be used in any different area.
Smooth surface roads maybe quiet but in areas where run off isn't efficient enough aquaplaning can occur, very coarse surfaces can be better for roads that ice up to an extent so many factors need to be taken into account.

The tarmac surface layer now in common use in Europe and the UK for A roads and Motorways was originally developed to minimise surface water retention and thus reduce the risk of aquaplaning. It is very porous. It was unpredicted that this would result in a quieter ride with most types of tyres.
This is because the amount of air trapped in the contact area was significantly reduced - the trapped air had somewhere to escape through the porous tarmac rather than be ejected sideways at the surface which resulted in a roaring sound.
On the subject of grit dressed roads - it is the case that when first laid they have greater grip than smooth tarmac - but the grit eventually wears to a highly polished and smooth surface which reduces the overall coefficient of friction with rubber tyres.
Hence both arguments are true
Newly gritted surfaces have a higher coefficient of friction than smooth tarmac - but this is soon lost when the protruding grit is worn down to a smooth surface. Gritted surfaces, new or worn, are always noisier than the modern porous tarmac.
Smooth porous tarmac has a slightly lower coefficient of friction, but this remains almost constant for the life of the surface. Hence porous tarmac roads , compared with gritted roads, have less noise and a higher coefficient of friction (on average) over the life of each surface.
Gritted roads using unprocessed tarmac and rock chippings are much cheaper than porous tarmac and have a longer life - hence their continuing use in the UK on roads with a speed limit of less than 60 mph (95 kph) where aquaplaning is not considered to be a serious factor.
And there I rest my case m'Lord

As Alan said, the course stuff does wear down but it is infinitely more efficient in providing traction in problem areas.

I was doing some research on the subject of road surfaces and grip just recently and found this article very informative... :goodjob:Good stuff Rusty. I still have a heap of charts from Goodyear which I used in training which say much the same thing.

There's a section of road going uphill to Buderim near where I live which over the last few years has been the subject of numerous single car accidents - running off the road in the wet. After years of denying the surface was at fault, the council finally replaced it. No accidents since.
