Coworker suffered uneven wear but not necessarily cupping on his 03 vibe.
He also ran really sticky tires, Cooper Xeons (?) and was having pulling/ jerking issues. We hypothesised that a small amount of built in slip was binding up from the overly sticky tires.
He tried getting it aligned but needed shims or other hardware and the shop never called him back when/if the parts came in... so he gave up.
