New 540ixMsporta little disappointed
This is a great car and a big step up from my 16 340iMsport. Unfortunately, on 19 AS Conti ProSports SSR tires the ride is quite a bit more jarring than I was hoping. I have the 704 suspension. Even running 3psi under inflated the suspension is not happy with these NJ roads. Any recommendations, other than moving! Appreciated.

I have read several complaints about runflats, and I'm thinking about switching to "go flats" on my car. I got the OEM spare tire option when I ordered the car--you can buy it from a dealer or online but the price may be quite steep and trunk space is compromised.
The stiff sidewalls of runflats really compromise the ride quality--with low profile tires the effect is exacerbated. You may have more bubbles/blowouts as well |

Sounds like you would have enjoyed the dynamic damper option, but too late now. Consider switching to non run flat grand touring tires such as Michelin and get an inflator kit.

Obviously those drivers desiring a less jarring response from potholes, may find non run flats to be a better ride. But buy quality, not crap, because in the non run flat world there's a lot of crap being sold at tire stores.

Next time I suggest looking at the dynamic damper option.

I got the dymanic dampers and glad I did. I had the 704 suspension on my prior car and my wife hated it leading me to get the dymanic dampers.
But that won't help you. Best advice is what you have received above...changing tires. |

the newer runflats ARE better, but not the best. I have the Pirellis and have already had two tires bubble. I have no real other option since i drive so much and won't compromise trunk space. If I did change, I'd get michelins for sure, always the best

It always amazes that many who factory order expensive bimmers don't add Adaptive Suspension/Dynamic Chassis Control. Out of all options, it's the one that has the most transformative effect regardless of your driving style. Basically a $700 bargain that negates the need to change to Non-RFT. I have driven the G30 with and without adaptive suspension and the differencd is night and day. Handling, weight transfer, comfort, body roll is so improved that it feels like a different car. It transforms the car from good to exceptional. I have specced it on both my cars that will be delivered soon and I will unlikely never want to buy a BMW without the option. The only reason not to add it if you plan to use aftermarket springs and shocks.

If you wanted a truly "better" sport suspension you'd need to order the dynamic handling package on a 540. A pretty expensive option.

I specifically chose NOT to have the adaptive suspension on my otherwise fully loaded 540iX G31. There were several reasons for that:
So, now you have several (new) reasons to be amazed at I miss the Goldilocks tuning of older days on BMW, where the car just felt "right". The passive M-Sport is, IMHO, closest to that. Also, even though RFTs have become much better there is no comparison between those and the premium non-RFTs and no amount of trick suspension can compensate for the reduced unsprung mass - you will always have the sensation of moving from leaden boots to running trainers.. |

Do yourself a favor and follow the tire inflation recommendation in idrive. If you need to soften the ride, switch to non rft tires. It makes a big difference. |

Yes echo about tyre pressures if only from ensuring that you get the best wear wise from them.
I have a shortcut button assigned to the tyre pressures so I can keep an eye on them especially when the ambient temps drop and the pressures reduce. Re default mode I think I've seen here that that can be coded if you are prepared to go down that route, other more experienced coders will be able to confirm that either way. |

Tyre brand choice on the other hand is far more important. |

Correct. G30 has BDC_Body module and you can FDL code to remember last driving mode used. Can also FDL code new default driving mode.

Why don't Bmw offer these features when they have taken the trouble to include it in the code?
I mean if they never intended it to be a user option , why? I can't see the point even from when they are testing prior to launch? |

I imagine in US, the default mode is always Comfort to allow BMW to obtain the EPA ratings on the window sticker. Also, I'm pretty sure dealers would have customers coming in wondering why their car lost power......All because they set Eco mode and forgot to move it back to Comfort.
