I can’t give you a guaranteed option until I test fit on my car but I can certainly give you my current research.
I have settled on the 22” wheel size due to availability of tires.
Option 1: Tesla Model X plain turbine wheels ($5500 option at sale time but much cheaper on eBay) - 22x9 front and 22x10 rear. Same exact wheel hub bore and bolt pattern, a direct fit. 36lb front and 42lb rear. Weight capacity unknown.
Option 2: Range Rover SVR forged wheels: 950kg capacity, 22x10 square setup. Wheel weight unknown, offset 42.5 which may require a 5mm spacer up front. Bolt pattern is the same, center ring will be required for proper fitment.
I am investing in option 1, with option 2 as a backup.
I am in New York if you wanted to stop by and test fit a wheel.
Good chance I will have a Gravity of my own within the month if not 2 weeks.
