Having problems with bad vibration between 45 and 65 mph, I have aftermarket wheels that were just balanced when I got new tires put on. If i throw the stock back on i can slightly feel the shake but nowhere near as much. I've been driving on these 17" vision wheels for over a year with no problem and even put them on another car today to rule out any being bent and rode smooth as ever. I replaced both drive axles in case they were bent, I'm not finding any loose ball joints or anything. Wondering what this could be and why it's so much more noticeable with the A.M wheels that dont differ much from oem wheels, just a little in offset and width and like I said no problems for over a year. Banging my head against the wall on this one, please help!

 

Wheel bearings?
