One question to be asked (maybe already answered):
Will there be an option to program in different rolling diameters (i.e revs per mile) to correct speedo, etc? My G-wagen allows a (limited) selection. I run Yokohama Geolander AT's 275/65R18's (32" vs stock 30.5") and I was able (with my mechanics computer) to compensate. My D90 runs on 33" BFG MT 285/75R16 (33.1" vs stock 31.7") and could do a mechanical gearing on the speedo output, but never bothered.
Hoping the IG has the ability to reprogram!

For around $200 you can get an aftermarket handheld re-calibration tool for Jeeps and other vehicles (like the one below).

JK ProCal Module - American Expedition Vehicles - AEV

Pro Cal is a one-stop tool for Jeep JK owners to correct speedometer to gear ratio, optimize ESP, recalibrate tire pressure monitor, clear codes, and more!

Given Ineos' pledge to be open-source with service and the aftermarket, one would assume they would make this easy. But who knows...

Thanks for your permission

Now you don't have to ask your wife

Although I am not interested at all (at least for the time being, but probably never) in changing tire size and other things, I think this is a legitimate wish, they should provide this possibility

There's many a man would be very happy with an extra 21,5 mm...............
But in reality, it does make a difference in rough terrain. Aired down, the contact patch is a good bit larger...

Actually the contact patch is a function of, and proportional to tyre pressure. A 31’ tyre will have the same contact patch as a 33’ tyre, if they have the same pressure. However the rim on the 33 will be further from the ground, good for preventing tyre pinching on obstacles. Thus the 33 can be run at lower pressures for the same rim clearance, giving it a bigger contact patch. So it is the ability to run lower pressures in the 33, that gives you a larger contact patch than the 31.

I would be interested to know why you want wide 33” tyres. Is it for the looks or for a specific purpose?

More mud and sand here than whatever you'd need skinny, tall tires for (whatever that might be). I'd think tall, skinny tires would be very efficient at digging holes and getting sunk quickly in mud. Look is a large consideration, as well.

Edit to add: My experience with being offroad working in the US Border Patrol, we had to use the trucks as they were, with highway tire pressures and did not have the equipment to air down or up. Hence, my comment of operating a wider tire at highway pressure giving more contact. Yes, I did watch the first video below, but still say that tall skinny tires look like they enjoy relations with other men.
