Likely can be a few things. I'm not tire professional, but I've talked to a few people and this is what they told me...

1. Depending if your ZCP is aftermarket or not, the bore for your wheel can be made slightly larger which means it's a slide in fit. A more speciallized or professional wheel company would make the bore slightly smaller for a very tight fit. What I mean is that you may need a hammer to lightly push out the wheels when your installing or removing.

2. Balancing machine out of spec or the guy who's doing the job basically doesn't care and want to get the job done.. You may experience this problem from new technicians.

3. After tires are balanced onto the wheels. Make sure you don't go adjusting tire pressure right away. Also don't driver like you stole the car once your wheels are mounted. Between the tires are some lubricants that are still wet. By lowering pressure, hard accel, or hard braking can throw off the balance and cause the tires to lightly spin out of place.

4. Make sure all tire pressure is correct.

5. retorque the wheels after 25-50 miles.
