Wheel/Tire size options

[RM-S8]

So, I'm very hesitant driving the Sapphire.
Why? Potholes, potholes, potholes.
I've got one already last year, rear 21" tire. Not a pleasant experience when it happens on the left lane highway.
I'd love to drive it more, to far exceed my puny 1,150 miles (as of now).
I dont' know much about wheels, tire sizes, tire circumference (back to front) and such. One thing I know, whatever I do it has to clear huge front calipers.
So, here comes the question to my fellow members.
What if I replace my 21'rear wheels/tires with a set of the front 20' wheel tires instead?
The looks are not the same, I know, but i don't really care, just wanna drive the car more.
Or, if anybody have a better idea?
Maybe, ideally get 19" tires, all four? Possible?

My suspicion is you'd have trouble with traction if you ever push it any significant amount, but that really depends on which tires you use more than which wheels. I just know that Lucid spent a lot of time benchmarking and carefully selecting their tires for the Sapphire, largely due to the need to handle that insane power and, more importantly, torque.

But I don't know the answer for sure!

The Sapphire manual has a bunch of info at the end about drive ratios and things, but I am not the right one to do "wheel math" heh. Figured it had some useful info though: https://lucidmotors.com/media/document/Lucid-Air-Sapphire-Owners-Manual_en-US.pdf

I would send an email to Lucid and ask them.

also, it would be a great idea to tell them if you could have an option to play with torque and HP or predefined configuration of the power like GT, GTP and pure even hhh so when you are installing lower specs tires, you do not wear them off.

Whew! So glad I didn't get a Sapphire with the cheap tires.

About to swap in the 21" summer Pirellis... now that temps are consistently above 40 degrees F in Philly. Don't see a March surprise Nor Easter...
Headed into 3 rd season on same tires. Very happy with them. Run mine at 44 - 45 psi. Keep the car below 20 mph to give time to avoid road hazards.

49 psi on the 19 " Pirelli A/S tires. I go as fast a I can on them ( unless wife is with me ).
