No, depends what tyre you are using. If you use premium tyre or UHP tyre like PS3, PSS, Assy 2, they will give you better handling and wet performance. Just ask your tyre shop and most of them able to give you more professional advise and choice.

According to BMW, all of their vehicles that uses run flat technology have their suspension and braking components set up to accommodate Run flat tyres. Should you decided to change to non run flat, it may alters the driving and handling characteristics of your vehicle. It is for this reason that this modification is not recommended by BMW as a manufacturer.
It stand true to certain extend. If you enjoy driving on super high speed. The differences is noticeable.
For normal driving. NRF out perform RFT. (Subject to the type of tyres used)
As for your become too soft question. Changing tyres doesn't affect that much.

Re: Coming 5 years old E60
yes, i will inflate my tyre to a higher pressure of at least 34-36 psi when i go in excess of 160km/h or beyond.
high speed=higher pressure & temperature within the tyre.
therefore, you need more air in the tyre to sustain that higher pressure and temperature.
It is also the reason why deflated or punctured tyre would blow if continue to travel at high speed.

Re: Coming 5 years old E60
i think you got it in reverse. shouldn't you inflate it to a slightly LOWER psi? because at sustained high speeds, the pressure and temp will go up, so you need lower pressure to start with. i suggest just keep to the recommended tyre pressure for your tyres when tyres are cold, that should do.
a punctured tyre at high speeds will not blow but be shredded to bits by the rims and the road.

The pressure would also depend on the load on the car ......

Re: Coming 5 years old E60
I'm staring so hard on my b-pillar that my eyes hurts. Yet I cannot find the information you have on your car. BMW recommended tyre pressure for 160km/hr.
I'm starting to have second thoughts about my car.
Can you post a picture of your b-pillar to show me the real thing?

refer to car on left & right with the same load but different speed.

My owner handbook didn't have such specific information. I think I got a lemon!
I wonder if BMW encode this information somewhere in the manual which we need to either burn with fire or soak with water to reveal it.
My b-pillar sticker only show a table stating recommended pressure for specific load scenario on different tyre sizes.
My manual even worse. Only breifly described about tyres and pressure and nothing more.
