Hello everyone,
I bought chinese wheels on my car and after using them for about a month, the car is shaking on low speeds (80km/h). I went to a shop and he told me that there is like a space between the original rim space and the rim itself. What should I do in this case? Can I fix the problem without changing the rims?

Thank you

 

Sounds like Hub Rings. If it is, then go with steel or aluminum, plastic can dry rot/get brittle over time.

 

Could also be a warped/bent rim since you bought cheap chinese wheels

 

This would be my first solution based on what mechanic is telling you. Need to know ID of new rim hubs and get rings with w/ an outer ID that matches them and an ID of 66.1mm.
