Take the tire off and spin it on a balancer. You'll see a hop if the wheel is not round.
I have 17x9 ARC8s and I've pretty much abused them in Korea. I hit countless potholes and bumps. Even launched my car on a highway expansion joint (the roads in Korea are THAT bad...I may have been slightly speeding too!). These wheels have held up really well. I would be surprised if you messed them up considering that your description does not include any serious impacts to the wheels.
