I'm obsessed with NVH. I would have bought a Lexus LS if not for the 90's engine, so I ended up with F01.

The road noise was greatly improved when I swapped the horrendous OEM 20" Continental Excellence RFT for 20" Yokohama Advan Sport non-RFT. Impact and rolling noise are much more subdued now.

The wind & ambient noise is BMW signature. BMW doesn't use double pane / laminated glass like Lexus does, so my F01 is way noisier in that respect than my ex Lexus GS. From what I understand the same is true for G11/12, still no double pane glass.

There are so many reasons why the 7 Series NVH opinions are so diverse:
  • Type of roads you drive. Smooth asphalt vs concrete slabs.
  • Lack of perspective. If you only drove noisier cars, the 7 will seem very quiet.
  • Environment. Wind direction, wet roads, etc.
  • Shoes. Stupid OEM RFT vs quiet non-RFT aftermarket.
  • Driving style. Stereo volume, speed, windows down, etc.
  • Attention. Same car I consider very noisy, my wife is absolutely fine with it.

A man in the tyre shop told me not to change the run flats on my G11 X Drive because it might ruin the 4WD and or the AIR Suspension

This is surely nonsense right?

Still trying to find someone on the world wide web who has done the G11 Run Flat dump.

If you search this forum, you will find many people who swapped out RFTs. Most are happy. Obviously need a solution in case of a flat.

Yes, it's nonsense. I replace the run flats every time I get a new 7 series. I do this every three years because I lease. It's never a problem and it makes a big difference.

I might have been tempted to swap out my tires but I got two flat tires in past 4 months. The convenience of being able to drive my car around and not have my life stopped wins out.

I have had non run flat tires on my 7 series for the last 9 years. Not a single flat tire. But I also have the mini spare option just in case.

Although my car runs on RF tires I have to admit this is the quietest car I have ever driven. The OP should take his car back to the dealer. Sometimes simple things like defective weatherstripping can generate road noise inside the cabin.

The newer run flats are better than they used to be but they are still a lot noisier than non run flats, especially as the tires wear down. When you switch to non fun flats its even quieter and smoother ride. Definitely worth it if you are sensitive to road noise and ride smoothness.

Big difference after switching out my 21" RFT to Mich Sport 4 Non RFT. Also applied Honda Shin Etsu Grease to all the door rubber seals which made a difference as well. Seals are one thing people forget to treat since they loose their performance over time.

This is such a good idea. Thank you! Iíll have to try it as Iím definitely one of the people who think this car is entirely too noisy.

I have a 2019 740i and find that it is very quiet most of the time. Road surface is definitely a big factor in road noise as the car will glide along serenely on newer surfaces but sometimes has significant road roar on worn surfaces. Tire type and wear also contribute to the overall noise issue. I'm somewhat surprised how well the car rides on 20" wheels with Pirelli P Zero RFT's only occasionally do I notice shock tremors that I think are a result of the low profile tires. I have access to a set of stock 18" wheels with Michelin RFT's and I may swap them to see if there is significant difference. Note: BMW tire pressure recommendations for the USA are based on full load plus cargo, a condition I almost never have. In Europe, the recommended pressures are significantly lower for light loads, so I run my tires 5 psi below BMW's USA recommendation, that makes a huge difference in ride comfort.

I'll give a different perspective: bought a 2019 ram 1500 a few weeks ago to haul my dirtbikes. And I have to admit, the road/tire/wind noise is almost non-existent on the truck. And we are talking about an American truck, where body panels don't line up, fit and finish is a bit of a joke. But it is considerably better suspended and isolated. Going back and forth between my G12 and the RAM feel a bit weird, and you keep thinking "what the ....".
But to contrast the suspension and body isolation qualities, the engine/exhaust noise on the RAM is pretty bad, and in a bad way. The audio system is a joke.
So it clearly demonstrates that the road noise can be effectively dealt with, and the G12 lacks, a lot in this department.

Well, the good news is that the 2020 is supposed to add increased insulation to dampen noise in the C pillars. So that would go a long way to increasing the quietness of the car. I agree it could be better for sure.

I wonder if it is easy to add this insulation in our cars

A big reason for the reduced road noise coming from a pickup truck is that youíre quite a bit higher off the ground vs. a 7 Series.

I experienced a similar situation hopping between the X5 and the 750.

You don't hop between an X5 and a 750. You walk gracefully.

Sure. Just go to Home depot and get a few cans of expanding foam and spray it in every hole you find.

Automotive foam might be better

The grease gets all over the body when the doors close, I would wipe it down with alcohol after a week. Don't use alcohol on the rubber seals just areas around it.
