Ok so I have been thinking about the issue for sometime and experimenting. I think I may have found the solution. The issue is/are the centric rings.

I swapped the rings for the left and right front and I do not have the vibration going from 55-65 anymore. The ride is rock solid...no shimmy..nothing..ziltch..nada.

I have ordered aluminum/metal rings and the plastic ones that I took off do look to be in bad shape before swapping them. I think with the weight of the tires and the rings being being plastic, overtime got deformed. I am 99% sure this is what it was. This also explains why initially there was no vibration.

Will update once I get new rings. I am also going to test at higher speeds (70+)

Thanks for everyone for their help.
