Hi Bernie,

Firstly, I would make sure that all 4 wheels/tires are perfectly balanced using a good/calibrated machine (road force if possible).

Secondly, do the wheels you bought need any hub centric rings?

Thirdly, in some very rare cases replica wheels are just not manufactured to the same standards as OEM and could cause a problem. But if the wheels balance I wouldn't worry too much about a manufacturing issue.
