2015 Tacoma Wheel advice

hello all, I just ordered a 3" bilstein lift for my 2015 sr5 access cab 4x4. I wanna run 265/70/17 tires. The only hang up I have is what wheels to run... as far as backspacing/offset. I've researched for a couple days now and can't really get a straight answer. I'd like a slightly aggressive stance. Maybe just beyond the wheel well but not like inches beyond where I have to worry about sand blasting my rig or messing with fender flares. I was thinking -4.5 back space and -12 offset, or would that push me way out?? Thanks guys.

 

Any advice... haha

 

Here's a pic of 275's on 9" wheels with -12 offset. Zero offset would be about a half inch closer to the flares.

 

Perfect. Thanks 3coma!
