Tire Rub with fender trimming

Hello,
I have a 2010 DC short bed with Billy 5100's all the way around with the fronts at the 2.5 setting and wheelers AAL in the back. I have wheels with a 4.5 inch backspace and I am running 285/75/16 Yokohama Geolander AT tires but with the 4.5 inch backspace and some inner fender trimming the tires still rub at full lock. My question is if I were to add a small wheel spacer would it help with the rubbing issue? If anyone has any pics that are running 4.5 inch backspaced wheels with spacers as well it would really help.

 

Cab Mount Chop is more then likely needed.

 

It's not the wheels. It's your caster and they need to be moved forward. Alignment numbers will tell the story. Ideal setting would be zero camber, zero toe, +2.5 caster at the least. Usually not attainable without going aftermarket upper control arms.

 

I have the Camburg UCA's with the 1.25 uniball so this can't be it I wouldn't think.

 

I am pretty positive it is rubbing in the back part of the inner fender closest to the front doors. I know lifting it a little higher by getting some OME 885 coils with the top plate spacers and setting the billy's back down to the 0 lift setting is an option but I was just wondering if the wheel spacer would be a quicker cheaper fix.
