2012 Wagon Auto
Purchased new. 2500 miles on now.
Changed stock tires to Bridgestone Potenza RE970AS Pole Position (245/45-19 98W and 275/40-19 101W).
Everything else is stock.
About 8-900 miles since the change.
At highway speeds (say 55-70) i'm getting a pretty significant vibration. I can feel it through the pedals, seat and steering wheel. I can see and feel the headrest of the (empty) passenger seat vibrating.
Seems to be there at all those speeds, at any revs, and at any throttle.
TPMS reports good, even tire pressure (have not checked manually yet).
Tried a few road surfaces and it is similar on them all.
No particular noise and nothing visual on the wheels/tires when stationary.
Any ideas? Anything I should check/do?
