4W Alignment and Cupping/Feathering

[Stoneman]

Hello,

I have a 2007 Impreza (base) that has some cupping/feathering wear on
all four tires (outside edges). Last year I was in a car accident and
all four wheels were re-aligned. I suspect I have some toe-in or
toe-out issues. The car drives perfectly straight, and I rotate the
tires every 6 months. Any advice would be appreciated.

I've never seen an AWD that didn't display this characteristic. I typically
inflate tires to maximum inflation to compensate.
