Stock wheels without lift

[Spp1919]

what is the biggest tire I can run on these wheels without lift? 2021 ram 1500 Laramie

if I did do a 2” spacer lift could I run 33/12.5r20? Thanks in advance and sorry I’m sure this has been asked a lot but I’m looking for specific to these.

I wouldn’t swear to it, but I’m pretty sure on stock wheels you can get away with 33’s, on a 2.5 inch level you can run 35’s, I think anyways.
