1/2 T 50’ GMC witha severe camber issue on both sides………..built a fixture and 20 ton bottle Jack.
Bent the cold axle back to 0 camber.
If your in spec I would not change due to tire choice. I ran radials on the 1/2t in the photos.
Are you sure you didn't install the spindles upside down? I did that on one of mine when redoing kingpins till I eyeballed it and said OOPS!
