I am suspect the wheel that we saw on the tester model 3 is the wheel what underneath the Aero wheel cover. Look at the wheel's valve stem location between two spoke on the red model 3. The valve stem location is offset to the side of the spoke to accommodate the Aero cover design. I had never seen any wheel (OEM or aftermarket) that with an offset valve stem between two spokes. So it is designed to go underneath the Aero cover. Also look at the wheel's center hub, there are threads which are for the Aero cover center bolt to attach on to the wheel. What do you guys think?
