I have a 1997 Acura Integra and am going through rear tires each month. I took it to the alignment shop and they can't correct it. They also said nothing seemed broken or bent. I took it to a body shop to see what they would say and same story, nothing is bent. The car is stock ride height which I heard if it's lowered may cause that but I'm running out of options and patience buying two tires each month!!!
the tires are tilted (camber) and the tires are eating away from the inside out...
