a lady i know gave me a set of stock aluminum rims, but a guy at a shop told her that one of them is bent, ive checked these rims up and down, and can't seem to find a bend anywhere... i think he was just tryin to make money off of here by tellin her this... but i was just wondering if there is any way to check for a rim being bent? ive set them on flat surfaces, and they dont rock back and forth, they all sit flat... so im not sure what else i could do

 

Spin them on a flat, smooth, surface. See if they wobble at all.

 

I BOLT THEM TO A FRONT HUB AND SPIN EM TA SEE, BUT ITS NOT PERFECT, so try gettin them balanced or spun on a balance machine

 

I meant to just roll them down a hill, but above method works too.
