Max tire size on 17" wheels and 2.5 inch lift?

I'm sure this is somewhere in the community and the search bar was no help. I've seen 37s and 38s but what is truly the largest size tire someone can fit? Also taking into account a new bumper and wider fiberglass fender flares.

So much pages but I haven't seen anybody post 17s on anything bigger than 37s

 

Your probably going to have to dig a bit and get creative in your search criteria to find your answer. I'd be shocked if they fit on 2.5" of lift.
