Don’t skimp on the load rating.

I'm not sure.
The Pirelli PZ5 summer tires that Lucid mounts on the large wheels happen to have the load ratings Lucid gave you. But the Michelin Primacy A/S that Lucid mounts on the Gravity with the mid-size wheels has a front load rating of 108, not the 109 the service team told you was necessary.
So I suspect there's some wiggle room. The Pirelli Scorpion all-seasons for the largest Gravity wheels have a total load capacity of 8,486 pounds -- 2,540 pounds above the gross vehicle weight of the heaviest Gravity version. So that means you'd have to have well over a ton of passengers and cargo in the car to hit the load limit of the tires, or load one end of the car far more heavily than the other to exceed the Scorpion's load capacity.
Generally, Tire Rack will not list tires on their website as available for a vehicle if they are not compatible with that vehicle's requirements. (However, they will sell -- as opposed to list -- some incompatible tires in certain circumstances if the buyer signs a liability waiver to purchase them.)
Bottom line . . . I don't really know what to tell you here. I suspect the Scorpions would be okay to use unless you're going to use the car for really heavy-duty hauling or towing. But that's just a personal opinion based on no real technical knowledge of the matter.
Got it.
I appreciate your detailed response.

I also suspect that the newest generation of premium tires are being engineered for EVs that are usually much heavier than their ICE counterparts. For example, there are versions of the Cadillac Escalade IQ that weigh 3,000 pounds more than the heaviest Gravity, and tire manufacturers have to take such vehicles into account.
So the fact that the Pirelli PZ5 used on the Gravity has such a high load rating may not be because the Gravity requires it, but because they want the tire to be suitable for even heavier vehicles as well.
But, again . . . just the musings of a non-expert.
My plan to reduce wheels sizes to get better tire selection and prices has worked. Went to local Americas Tires and they offered me this set of wheels and tires, with caviat that it may not fit, in which case order would be cancelled at no charge. Paid about the same as I would for just new summer Pirelli's, but got tires that should last longer than one year and cost half to replace next time.
Would it have been possible to put the 21 wheels in front to make a square config.?
I would love to know what kind of range you are getting with this and any difference in ride quality.
I am currently on the fence about getting the winter wheel package from Lucid, which is around $ 4,200.

Look at the rear wheel with a flash light for the harmonic balancer, there is a good chance it’s physically touching the inside of the barrel.
Just on top of the parking brake.

I bit the bullet for the Lucid winter wheel/tire package and paid $3700 when I leased car. Figure I will get "some" money if I need to get rid of them at end of lease.
I have had great experience with the winter set in Michigan and really like the 22/23 look and feel during the summer. It's almost two different cars for part of each year.
I don't pay much attention to changes in efficiency, as I have never had over 2.53 ever. Most of my driving is 10 miles a day in suburban detroit and I treat the go pedal as an on/off switch; suppose I should try harder. I spend about $50 a month to drive my fabulous vehicle, so saving $10 a month sort of seems contrary to paying for 1,070. HP.
YMMV
Maybe, but rears are wider, not sure if fronts can be the same width, otherwise they are still not all square.
P.S. I have zero expertise in tires, so talking out of my rear hatch here.
I am also leasing it and may buy out at the end of the lease if the owner experience starts to improve.
I imagine getting the winter/tire package, using it during winter, getting myself a set of all-season tires, and selling the winter ones to recoup some of the loss.

That’s great to hear!
