AT and MT tire alternatives for 2019 G550
That all said, I have had excellent service from the below Yokohama AT tire, on a half ton truck and they are one of the only AT tires with at least an "H" speed rating. While I don't plan on cruising at triple digit speeds too often, I always want that saftey factor. Also, the higher speed rating normally means a higher quality tire. The ones on our truck only required a few ounces to balance, while the original Bridgstone tires required more than 5 times as much!
Let me know your thoughts on these tires. You would have to go from 50 to 55 on the profile, but this would make almost no difference on the speedo. I am not sure if the dealer can update the tire size on the new G, but they should be able to soon enough...

Since the stock spare is already 0.5" smaller than the stock tires, I decided to get a 245/60R20 Cooper Discoverer SRX (just a cheap tire). This is about 0.2" smaller than the Grabber, but it will always be this diameter while the Grabber will get smaller with time. Given the apparent narrowness of the tire cover, I suspect the 245 width tire will be a better fit within the cover. Although, I won't know for sure until after installation.
General Grabber A/T X
I plan hold onto the stock Pirellis until someone doing a lease turn-in needs a fresh set of tires. Unless someone wants them now on the cheap.

The rim size doesn’t really matter in determining the vehicle height. The height of the vehicle is only affected when the exterior dismeter of the tire is changed. I went from 275/50R20 to 275/55R20 which has a diameter that is one inch taller. Since the height is only affected from the axle to the ground, my G is a half inch taller.
