Vibration K11

[CMF_Ian Smith]

I have a K11 that has a slight vibration over 65mph. It spoils the drive and it is impossible to 'drive through'. I have had the wheel balancing checked by two tyre depots and there is no problem there. I had bought 4 new Falken tyres back in Nov.09 and suspected that the tyres were 'iffy. So I had all 4 removed and replaced with Avons. The depot ran the car up a very smooth road and...no difference whatsoever. So we put the Falkens back on.
Now I am stuck and thought that my fellow Micrafiles may have some ideas? It is not a massive vibration but you can feel it on the steering wheel and the gearshift. It is really annoying because 65/70mph is a good cruising speed (with a good tailwind of course!)
Look forward to some ideas from the experts! Please let it be a simple solution like 'remove all the plastic wheel trims!'
Regards to all

driveshaft maybe ian ?
i would jack each corner up and run the wheel up to 70mph to find out which side is at fault

could be a shocker letting the wheel flop , the wheel will do a very fast shimer up and down with the slightest bump . get someone to follow and watch the wheels ..
