I'm not sure, it seems like normal hard plastic, but the problem is that the gap wont close with the rim on it, it only closes without the rim, and when i close the gap without the rim, the rim dont fit
So I bought some plastic drift tires with rims off amazon from a company calle " Lafeina " , I got all 4 wheels and everything was looking good till I saw one of the tires had been cracked, idk if its from shipping or its a defect, I'm wondering if there is a way to fix this or should i Just get...
