Well, I found a solution for those of you who were looking for Center Caps for the factory Black wheels that are under the Wheel covers on you 16" wheels. I have attached photos below. Let me know what you think.
I know that this thread is abit old, however, I am looking for these elusive 66mm caps for the Kia Niro wheels. The link to Aliexpress shows the wheel caps at 60mm. Has someone bought these from Aliexpress and tried them and then confirmed that they worked?
