No luck with those tires. Two blown tires within a month and under 1,000 miles. These tires have since been delisted from TireRack and not allowed to be purchased via DiscountTire (to my knowledge) for the Lucid Air at 21".
The tires are not rated to hold the Lucid's weight by healthy marigins. Aggressive driving certainly did not help the cause on that one (eg. definitive no go for the Sapphire as is).
OEM is the only option unless you buy rims for a different size. OEMs have held up to the day to day abuse at over 5,500+ miles.
