Hi, Since having my rear tyres changed to Goodyear F1 assy 6 I have experienced a low pulsating drone from the rear behind my right ear. This did not seem to be there before I had them changed. I have removed the wheel and the tyre seems okay, I have wiggled the wheel on the car and found no play. This happens between 30 and 40 mph. Has anyone else had this happen or knows what it might be please? Mike.
