I ask this question at delivery so this is from Lucid engineer.
You could put 265s on the front of any air.
The 295s on the rear would not fit a standard air. There are modifications to the car in addition to the flare pieces compared to the other air models.
I have not yet pulled the rear wheel to look at the differences, but will post pictures in the future.
I was thinking of putting 265s 20” Sapphire rims all the way around on the DE just for fun. Also, to see where the front tire lines up to the fender.
