Rep Power: 245

okay..so today i went to the mall and came straight home and washed my car. when i was cleaning my rims. i realized it was messed up. looks like someone hit the edge of it. [the part of the rims that meets with the tire] and these are my right rear rims. my dad said it looks like a hit a curb when i was turning. but i know i didnt. but yeah, its something small but what i do? i have a lifetime warranty/structural/finish. with discount tire. do you think they'll do anything about it? i'll get a pic when i get the chance. So what to do?? go to discount and show them or dont even bother...
