anyone knows what kind of "seating surface" for oem 2011 prius lug nuts? i read someone posted on 2007 prius having a flat surface, our 2011 prius has flat or conical? in buying the aftermartket wheel lug nuts, what size? any recommendation. thanks in advance
Are you switching out the wheels? The Toyota alloys are flat. When I removed them and went with an aftermarket wheel, I had to change the lugs to conical.
