2020 trail boss Lt 22” wheel question

[BigjoeG]

What’s up guys, new to the forum, new to Chevy..... always been a Ram guy...... so I just purchased a 2020 satin steel trail boss LT...... I’ve been looking at aftermarket wheels because I feel the 18s look tiny on a crew cab standard bed... what can I get away with backspace and offset wise if I did a 22” wheel, with possibly a 285/50 22 Nitto terra grappler....for right now I didn’t  plan on doing a level. I won’t be off-roading the truck, it goes on the sand here and there but mostly a road warrior...... thanks for any input
