U will be just fine no spacer needed and no rubbing or zip tie surgery
After a lot of online research, I went with a ReadyLIFT front-end 1.5" leveling kit (SKU 66-19150) to accommodate 33X12.50R20 Nitto Ridge Grapplers mounted on ICON Alloy Compression 20x10 wheels with -19mm offset. Said combination went on my 2021 Ram Limited (Air Suspension) 4x4 Crew Cab. I haven't gone off-road yet, but I haven't felt any rubbing on-road. When I get a chance I try and measure turn-to-turn clearance.

33's shouldn't have any issues other than looking small with a lift/level.

I received some 33x12.50 tires from my brother who upgraded to 37s for his truck with a 6” lift. They’re like a month old. Will these cause any rubbing on my 2020 Ram 1500 Big Horn on the stock 20” wheels and stock suspension or will I need to get spacers for the wheels or maybe a leveling kit/lift kit?

Put them on and see. Depending on manufacturer, they may fit fine.

I haven’t been able to go get them mounted but I wanted to see if they were going to rub without the leveling kit up front. Just in case though I do have the leveling kit on hand if it’s needed.

I have 33 x 11.5 with no lift, plenty of room. Worst case would be rubbing on the plastic fender liner at full lock in reverse which is easily fixed or ignored

yeah, you definitely need the level kit to run 35's on stock wheels... i test fitted the tires without the level kit and they rubbed at left/right full lock.
