I am in the market for a new Tesla, and once again have been sucked into doing excessive internet research before the big purchase. I like the appearance of 21 inch wheels better but understand that the calculus needs to include substantially increased tire replacement costs. 19 inch wheels also supposedly ride better. However, it is possible to find affordable and attractive 20 inch aftermarket rims. From what I have been able to gather, tire costs are only a little bit more expensive at 245/40/20 than for 245/45/19, before jumping up a lot at the next size level up. I am not sure about wear rates or ride quality, but 20 inch wheels may be a sweet compromise: Gianelle Yerevan 20x8.5 Black Mach Chrome Lip High Offset I would love to hear from anybody who has tried multiple wheel sizes and has insight into differences in ride quality, wear rates, and economics. What offset would be acceptable?
