Tire size

[Forrest Alley]

I know this question has probably been asks before, but I'm new and I can't find it. So here goes, I have ordered a new 2020 2500 Longhorn off road package 4x4, I really don't want to lift the truck and would like to know what the tallest tire I can put on it without rubbing?.

The stock tires on my soon to be new 2021 3500 SRW are 33 inches. If I swap out the standard tires for new tires, and increase the size to 35 inch, will the dealer be able to adjust the electronics (speedometer, etc) to account for the change in wheel size?
