The car is very very comfortable on 19" tyres. But when taking a corner a bit sporty, you can feel the car wobble. It doesn't feel very very stable. What could this problem be?
Many people told me the 335d is a heavy engine and in combination with softer non-RFT (BMW's suspension for the E92 is designed for RFT), you get instable cornering.
What should I do? Is this true? Does the tyre pressure of a regular tyre need to be higher then a run flat one? The only solution they advise me is to go back to RFT (I still got my original ones - Bridgestones). Still I'm a bit afraid 19" + RFT will be to harsh of a ride.
I think you've jumped the gun by ditching the runflats so soon. They really are not a problem in terms of handling since the suspension is tuned specifically for them.
However, you really should not be feeling any cornering instability, just because of a change of tyres.
Are you certain that the goodyears have been properly fitted (ie. correct pressures, wheels balanced, alignment checked, tyres facing in the correct direction etc..)?
