Because we have noisy roads here (badly pitted concrete) a lot of road noise is present. On new black top no tire sounds. Concrete lots. Have seen ads for better insulation kits for fenders etc. Anybody try this? Any info appreciated.

maybe trying some of that dyno matt stuff for sound?

Damplifier Pro is also another good product. Behind the A-pillar, footwells (under pad/carpet) and in the doors should make a significant difference.

I have read Ziebart uses a stuff that reduces road noises but I have not tried it

In reality. No Sports suspension, larger tires, smaller wheels, etc. would really do the trick. I'm sure they have some thick insulation there as OEM (one would assume), but the extras couldn't hurt.

I attribute road noise to my tires. Sport suspension, low profile tires, 18" wheels as mentioned contribute to the problem. I have a 2010 E350 4 Matic with Pirelli PZero Nero 245/40 R18 97V all season tires as original equipment. On a pitted, rough or grooved pavement the tires are extremely loud. In decades of driving, ownership and operation of dozens of vehicles these are the loudest tires I have ever had.

My apologies I just found your post from 20 APR 12 in which you mentioned changing your tires to Continental DWS. Obviously it did not solve the problem.

no matter what kind of kit, will the dealer install it for you if you insist the road noise is fairly unacceptable? will it be a courtesy call or another non-warranty "big job" ?

Use Bridgestone GR90 tyres can reduce a lot of noice

NO dealer in their right mind would attempt this. Your best bet is a pro car audio shop.

[quote=RSIKR;5272578]I had 2010 & 2011 E350s w/ P Zero Neros and they were on the loud side. Had Conti Extreme Contact DWS installed on my 2012. They are definitely a better ride and quieter then P Zeros. Handling is not quite as good tho but will take the better ride and less noise. Exploring sound deadening material to install under the floor mats and possibly A pillers. These mods should be easy to install myself. I do not want to make this a complicated project.

Have occasion to often drive Lexus and 18" tires are quiet. So it would seem that sound isolation would be a big part and to a lesser the type of tire used.

Many tires are noisier on concrete roads, no matter what the design.

If you decide to change tires again now or when yours are worn down, here's an important resource for purchasing tires that are quieter than others:
http://www.tirerack.com/tires/tests/testSearch.jsp

You can also post over in the mbworld tire forum and make contact with one of their representatives there or, of course, by phone, etc.

If you're hearing whining noise that changes with the speed of the vehicle, then tires with a different tread pattern may indeed help.

If you're hearing - and feeling - a good bit of tire thumping, then a softer riding tire of a differently purposed style may help. For example, grand touring Michelins instead of UHP P Zero Nero's. Changing styles may result in some handling response differences.

As for the dealer installing aftermarket sound deadening packages as a courtesy, good luck with that! As KA said, they will undoubtedly tell you that MB packs a lot of sound absorbing material into the E sedans and your car meets OEM specs.

I have the P Zero Nero's on my E350C. Definitely a difference in road noise on different road surfaces. When it becomes annoying I take the cheapest road: I turn up the HK sound on Sirius BB King, after which I hear nothing but tears!

If you go the aftermarket sound deadening route, please let us know the results. Here's a good resource:

Thanks. Will do.

i understand but what if one keeps going back just for the same reason. the dealer can't just tell you go to pro car audio shop or change quieter tires, right ?

Arrie

Take a ride in a S class MB and take a note how quiet it is for road noise.

MB knows how to dampen road noise but it obviously is not done for E-Class. Very likely reason is to keep difference in quality between the classes other than just size of the vehicle and price tag.

It is so funny I own a 2006 Chrysler Pacifica and it is a lot quieter for road noise than my 2010 E550 with a set of very common low quality tires. And this very large vehicle handles very, very well when turning the wheel.

I just hope they would start making this awesome vehicle again...!

thekurgan

I would if I were the dealer ... good luck getting them to re-engineer the car or change tire brands for your ears when not many complain. If there was a TSB related to sound levels due to tires or lack of adequate sound insulation, you may get them to do something based on the MB solution, which could be tires or additional sound dampening insulation.

K-A

Actually, I've seen S-Class owners complain about some road noise as well.

There's something going on with newer cars where they're getting significantly louder in terms of road noise than their predecessors. F10 5-Series, new A6, new E, new S, and a host of others I've heard complain about too much more road noise.

With the E, my theory in the flubbed harshness over rough patches and noise over those same patches is that in their quest to try and exude "Sportiness" from the car, they went too far into the easy direction. I.e, anyone can make a car harsh and loud, but to actually make it SPORTIER (which the E-Class is NOT, no matter how much you feel the road), you have to actually ENGINEER the "sportiness".

I feel that they wanted the car to be more communicative and sporty, but obviously couldn't give up the smooth serenity the E-Class is known for. Therefore we have this Jekyll/Hyde character.... super smooth and pin-drop silent on smooth roads, but jarring on rough roads.

Am seriously considering having Dynamat installed in my car. Great reviews on Amazon.

thekurgan

Check Damplifier Pro, it is far superior and easier to work with as well.

Have you used it on your Bluetec?

thekurgan

Not on the bluetec, but on my other car, a Z4 M Coupe, I used it to line the doors and the inner front wheel wells. It is easier to work with and more pliable than the dynamat. The bluetec has the 17" tires and wheels, and may help with less road noise (at least until the runflats start to wear
