inner two treads? wouldnt that be too much toe in?
either case, sounds like an alignment is needed...just make sure before you take it that the shop doing it knows , or has access to specs for these cars...... I took mine fairly soon after buying it and ( I had some weird wear too) luckily found a shop with a "seasoned" ( almost my age! lol...) guy who KNEW the specs.....18k later ,it still is good....
