What size rims and tires can I run

I have a 2014 tundra with a 3inch leveling kit.looking to do bigger tires and rims.hard to figure out what I can run without major modifications.
Anyone tried to run 33x12.5x20 rims with a -44?? Or what's the options???

Me personally, I would not run a -44 offset unless you want paint shredded. I would run an 18 inch wheel versus a 20. The 18's will give more sidewall and also a better ride. Post pics of your truck and the leveling kit. I have a 3/2 lift on mine and I run 285/70/18 (34's) on a 0 offset.
