I've got a 2000 C70 with 74k miles (owned it for 2 years). I recently had the tires (with 15K on them) rotated and balanced. I was informed the they showed cupping. Can anyone offer any info regarding this and what the cause and remedy is? Thanks!

 

I would believe that you have a bit of an alignment issue. You did not mention whether you felt the fronts or the rears were 'cupping'.
