New Taco owner needs advice...wheels, wheels,wheels

Purchased my first Taco two weeks ago. First mod....tires and wheels! 2017 4WD SR5 purchased with 245/75r16 Firestone Destination LE2’s on upgraded Toyota wheels. Would like to run BFG KO2 265/75r16 on new rims with no rubs, issues, etc. Not lifted. Any suggestions on wheels, backspacing, etc? Also adding Bushwacker pocket flares and would like a wider stance. Any help, photos appreciated.

 

I bought mine in 2016 and still need help.

 

After a lot of research I’m still uncertain. I know the look/performance I want but unsure the best route to take. Thought I’d cast the question into the experienced waters. Relative expensive endeavor so need all advice I can get.
