Now having the truck, I have to say, the wheels and tires look pretty big. Have the 20" all-terrains. They certainly fill up the wheel wells. On a car where you want little space in the fender wells, that's great. But, for an off-road oriented vehicle, was thinking of possibly dropping the series down a size. 34 inch tires almost feel a little too big for the Rivian. Coming down a size (60 instead of 65 series) would be 33". Basically would only add 1/4 inch or so in spacing from the fender wells, which is minimal. But, thinking it might look better and more proportionately sized for the size of the truck and would help with clearance if adding more offset to bring the wheels outward. Just a thought.
