Just put new tires on approx 3000 miles ago (falken sincera 828s, have round/square rotation holes in tread), have noticed front right tire is wearing much faster than the other three. wear is even across tire and ive checked ball joints and done the 3/9 and 12/6 test and nothing seems loose. car has 142000 miles on it only new suspension parts is endlinks all else original. anybody have any ideas what might ne wrong???
