Diagnosing a front end wiggle at 35mph

, if the car sits alot flat spots in tires, they work their way out after driving a few miles
I drive the car 1 to 2 times a week.

Bent rim,are they steel wheels
Rims were checked when tires were put on. OEM steel.
Other than that, do a front end shakedown, and check everything, even tire air pressure, Dont skip over things like actually looking at the tires because they are new etc

One of these days I'll get the front up on stands release the pressure off the tortion bars and shake the crap out of things to see how loose everything ready is.
