In all seriousness thou here's an actual tech response:
I think you need more lift in order to run the larger tires, looks like 44's would be a real tight squeeze, and to be honest for todays show trucks 44's really don't cut it anymore. Might want to get some lift springs or taller/stacked blocks just if you do that run dual triangulated ladder bars otherwise it will most likely wrap and cause bad things to happen.
And yea def beef those mounts up, make almost a "subframe' assembly with crossmembers and plenty of triangulation, other wise it just wont be safe at all.
