2009 cobalt ss 78k Miles rear tires worn from inside
 

as the title says my inside of my tires are just being eaten apart within 1 month of brand new tires. What solutions do i have? I have been told get a cobalt rear axle beam and have it replaced? we have independent torsion beam that doesnt get aligned should be fine. My front tires last perfect they last longer than the rear ones nd its a fwd.... any suggestions ?? what did you do to resolve this....?

also noticed rusting on steel under the vehicle. any solution to this??

thanks cobalt community for your input :):usa:
