hard to tell with the pic. stick your fingers in the tread. if the inside feels signifiacanlty lower than it's time for camber correction. most cars with low springs are going to wear a bit on the inside. slight difference (1/32- maybe 2/32)is ok. try getting one of the tread depth guages from a parts place. measure with those. take 3 readings. outside (bout half inch in), dead center and aobut a half inch before the other end.
