Bought new tires on Thursday, (Goodyear assurance max life) tech mounted and balanced them while we were installing the 180 thermostat. I live about an hour from work, and on the way home I had a noticeable vibration at 55-60. I figured maybe the balance was off, so today I asked if he could do a road force balance. He spent almost 3 hours making sure it was right on all 4 corners. Drove home and now it’s worse. Not noticeable at low speeds, but the faster I go the worse it gets. Could it be something besides the tires even though it only started immediately after the new tires?
