Tire Rubbing. Pinch Weld ?

[ARiley23]

Im currently running 305 55 20 and on full lock my tires rub on the frame, I bought some spacers to take care of that but with them on the tires rub completely against the inside of the wheel well and the fender flare. My question is has anyone ever run into this problem? and has anyone ever trimmed their pinch weld behind the wheel well liner before?

Instead of trimming the fender, just give it some more lift and sturdy coilsprings
