Hi Guys,
I'm running 19x9.5 with 265/35/19 tires on Model 3P and I noticed at speeds of 70mph+ I get a strange oscillating thumping sound emanating from the car with a little vibration under my seat. It seems to happen on and off when I'm driving. I could drive a couple miles and then it slowly fades away .. and then it comes back and intensity increases - so it doesn't happen all the time.
Hard to localize but it seems to be coming from the rear of the car.
Not sure what it could be (wheel imbalance, something rubbing on wheel, undertray loose and wind making it flap, etc) but just curious if anyone has encountered something
similar before.
Thanks,
Steve
