Hit a pot hole the size of an inverted mount everest on friday. To the eye it look to have a slight flat spot on the inside of the rim. But in the photos i took it's deceptive and now i'm not so sure. It drives alright, but is there a way of confirming?
You'd be surprised how many wheels have very slight flat spots in the rear of them, Without seeing it it's hard to say but as Mat said get it balanced and get them to check to make sure it's not too bad and that it's not cracked.
Those wheels are pretty robust so you should just be ok with a balance up.
