19" vs 20" Wheels

Hello,
I recently bought a pre-owned Lucid Air GT 2023 with 20" wheels. I was considering swapping to 19" for a longer range, but was wondering if it's worth it given that the car is now 3 years old. When I got the car it was at 426 miles @ 100%. Would anyone happen to know how many more miles I'd get if I went with 19" wheels @ 100%? I know there's some battery degradation because it's 2023, but I'm curious if it's just better to stick with 20" vs 19" value wise if I'm not gaining much more miles. The plan would basically run out the 20", then either replace them with new 20" or bite the bullet and pay for the change to 19". I'm also thinking in the long run 19" could be cheaper replacements, but the upfront cost, not sure if that's justified if the miles increase is minimal.

I’m getting up to 460 miles (4.1 m/kw) @ 100% on 19” wheels on my 2023 AGT. Obviously range will vary based on a number of factors with weather, speed, and elevation being the biggest. On that basis I average closer to 3.5 m/kw but it still puts me close to 400 miles in real world miles.

112 kWh battery on the AGT. I am on 19's and sometimes in warm weather on interstate drives get 4 m/kWh and have never gone below about 20% SOC on a trip. I usually get an average of 3.5 m/kWh so using 90 kWh yields 315 miles. Sure, I may get better efficiency and calibrate my mileage and charging based on actual efficiency. I also am certain to maintain tire pressure at 49 psi cold for my driving. We all may have different driving style and tolerance for low SOC but that is how I have driven for three plus years with no problem. Not sure that there is a material change in range with 20's inflated to spec, but it is less than the 19s. To me the 20's look better and definitely turn in better, but those are marginal considerations for me. Finally, a 300 plus mile drive is over four hours of seat time and I take a break and maybe even charge if it is convenient after less than three hours.

Appreciate the inputs, I guess from a lot of people's opinions, 20" seem fine when it comes to miles vs 19".
