Im messing up so bad, i meant to say carbon fiber.. God im stupid sometimes...

So Carbon Fiber Wheels (rims) not tires and not fiberglass <-- me

 

Forged alloy wheels are lighter than cast alloy wheels of the same design, but they are much more expensive. Carbon Fiber wheels if available in the future will be much more expensive than forged alloy wheels and most S owners can not afford it.

 

I have carbon fiber wheels ... on my bicycle.
