New to the forum, tire size help

[jgoff2011]

I"ve got an 03 yukon, slt 4x4. I just got some new rims. they have around a -6 offset, or dang near close, just did some quick measurements. They're 20x10. I've got torsion keys and can have them cranked a little more if needed. I'm wanting to run a 33x12.5 inch tire, preferably Nittos. Will this fit? I don't care to trim some. Also, I plan on removing the running boards. Any advice will be appreciated. I know there's three million people asking about this on here.
