BF Goodrich Ko2 285/70R17 or 275/70R17 with 3" Lift?

Need help guys trying to figure this out if there will be rubbing on those tires even with 3 inch lift?

 

I have 275/70/17's with a 3" lift and have no rubbing. I do have aftermarket wheels with 4.3" backspace though.
I regret not going 285's

 

Thanks bro really appreciate your feedback. i’ve seen other did 285 but wasn’t sure if they did a cmc on their truck.

 

No worries. Hopefully it was some insight for you. I noticed you have a 3rd gen so not sure if you'd need a cmc or not , but 2nd gens do.

 

My 285's rubbed both front and back wheel liner and the cab mount with a good alignment when stuffing with the front wheels turned. I had the CMC done and still need to trim the liner. I had tried remolding the liner with a heat gun but that hasnt been enough to stop the contact when off road.

 

I have a 2.5 inch lift in the front, and rub on the cab mount with 285/70r17. Need a CMC ASAP
