Fg slicks real or fake

How can i tell if they are real fg slicks from fake china man slicks?

Thanks for nothing but I find out how to tell

How

Sorry guys I been a way for a while, just moved and getting settled in now....
The easy way to tell is by looking at them, the fake china stuff material tends to be much shinier, that amount of plastic exceeds the amount of rubber which tend to make them have a glossy look and much different feel to them.
Even the plastic rims are made of a cheaper and weak plastic.
The china slicks wont smoke when heated up like the FG slicks do either.

So how do they perform vs the FG's?

I found out that the off-road ones are crappy, well the wheels are crappy. They deform when hitting hard on big hits.
