Had the winter wheels re-balanced this week, after experiencing a slight steeringwheel vibration.
THAT vibration is gone now, but I experience a tingling vibration through the floorboards.
This starts at @ 65 mph & continues up to about 75 - 80 mph.
It's enough to make your feet numb after a while.
Any suggestions from the vibration experts?
