275's 0n bullits on GT

Friend on mine has 17X9" 03-04 Cobra chromies on his 90 GT. 285-40-R17 Goodyear Eagle GSC's. No rubbing going straight. He told me he thinks the left rear is rubbing on turns, but I don't see any marks on the insides of his tires, so I don't know what the heck he is talking about!
