265/70/17 + 8.5" wheels, what exactly what must you trim? and what is cab rub?

i am very close to a final decision on my wheels. with each of my choices, the wheels will stick out about 2" compared to stock. it looks like i have to remove my mudflaps, do a bit of trimming.

i am sure i can do it, but i am curious, what has to be trimmed? any pictures?

what is cab rub and where does it rub?

where will the front mudflaps rub, and how to the Husky mudflaps help?

i have read about CNC mod, i will not be doing any extreme off roading.

thanks for all the great help so far!

 

On my 06 TRD with stock suspension I have 265/70/r17 with 1.25" spidertrax wheel spacers and they don't rub at all. I did have to remove my front mud flaps after I installed the spacers though

 

I have 265/75r16's. I have aftermarket rims with 1.25 more back spacing. Stock suspension. Mud flaps gone and I had to trim a small amount of fender flare and plastic. Around the mud flap area.
