sounds like u have no idea what is going on when it comes to aftermarket wheels dude....everytime i have changed my rims i have had to get a different set...it ensures that the wheel is center on the hub when they bolt it on....if they are all not dead center then u will have vibrations....AND THEY WILL NOT BREAK...unless u hit a curb at 100mph, and in a KIA i doubt that will happen...good luck man and get those on there b4 that shit drives u crazy
