The seat of the pants probably points to rear wheel issue - balancing or bent rim?

Do you know if they are the correct rims for the car? Specifically, does the centre bore match the hub, as this will cause a vibration at higher speeds?

As far as I know, I believe the CB on the D4s are 66.6mm, the D3s were 57.1mm, so if you had D3 rims on, then you'd get this vibration.

Thanks Steamship.

AFAIK they are the originals, 19 x9j 10 spoke Y. They fit snugly on the hub.

Flat spots on the tyres may also cause vibration.

OK thanks Conan. Rear tyres are new and the issue was there before but well worth a re-visit to the tyre dealer to check.

Are all tyres the same tread pattern? Though I ran a D2 on mismatched tyres and it went along no problems at all.

Runflats can be a nightmare, the ones on my 5 Series cause this when the obligatory sidewall bulge occurs around 100 miles after hitting the many potholes on the roads

Thanks Paul. Yep I agree. I guess I could swap rears to front to see if the effect changes then that would narrow it right down?
I even thought about trying the space saver but that also may be away with the fairies balance wise plus I'm limited to 50 mph.

Swapping front to back would help isolate the issue for sure
