Maybe you did get some from a older batch.
You can send them in and we will have a look for you.
We are always looking and testing new plastics that have a chance of withstanding 50MPH+ crashes but with the speeds and the weight these cars have, its always a uphill battle.
Since the 2 stages are lighter and constructed a different way, it opens a new chapter for us. In testing we have not had any tire or wheel failure.
