Before I shaved rubber off the tire, I would have a tire shop break them loose from the rim, rotate 180 degrees, reinflate, and balance. It is very common for tires to seat off center on the rim. After they stretch a bit, then they are more likely to seat on center. The Michelin truck tire book even instructs the installer to mount them, deflate, rotate, and reinflate. I have never seen an installer go to that trouble but the concept makes sense.
How out of round are they? Have you put a dial indicator on them? While you have the indicator out, check the rim runout too.
Report back when you resolve this please.
