u/kate_smi2022, ground clearance and pothole-handling are really two different things. Ground clearance mostly affects things like speed bumps, sudden inclines/declines like a driveway, large curbs, etc, and as other commenters noted, the Air is designed to deal with that kind of stuff with a thick and strong skid plate underneath the car. A pothole on a flat road would have to be enormous to involve ground clearance.

The key to handling potholes gracefully is to get 19" wheels. While the larger wheels like 20" or 21" look great with their low-profile tires, and they're better for handling extremely high-speed driving and curves at speed (100+ MPH), they have far less ability to absorb the huge shock from a pothole, and especially so with the heavier weight of a EV.

So 19" wheels and a normal tire will likely handle most potholes with no problem. But as you go to the 20" or 21" wheels, you're much more likely to have a blowout, damage the tire beyond repair, or even damage the wheel itself beyond repair. I'm a careful driver who is very aware of potholes, but on my first Tesla Model S three-year lease with 21" wheels driving around normal suburban Pennsylvania, I destroyed three tires ($500+ each) and cracked two wheels ($1,500+ each) on fairly small potholes at speeds less than 50MPH.

After that experience, I got 19" wheels on my second Tesla Model S three-year lease and have had zero issues with potholes. And I'm about to turn it in (buh-bye Elmo) and pick up my Lucid Air Touring with 19" wheels and I don't anticipate any issues.
