Out of sheer principle, I have a real problem with Tesla essentially forcing us to spend $1500 on decent looking wheels, to get away from the ugly base Aero wheels. So we could buy aftermarket 18 inch wheels and swap the tires over to them. I typed 18 x 8 wheels into google, and one of the first choices was a $110 replacement wheel for a Nissan Maxima that looked nice, and similar to the Tesla 19 inch wheels, but the bolt pattern was slightly off. But once we find suitable wheels, what about swapping the Tesla tire pressure sensors into them? It wouldn't surprise me if they made their tpms's just unique enough that they would not work in any non-Tesla wheel, to force us to buy their overpriced wheels.
