The OP who had cracks in the wheel was not using it on track. My bubbled carbon fiber failure did occur AFTER running <10 hot laps on track - note it did not fail WHILE on track, but after being parked.The thermal issue I would agree is a defect, but not the cracking if used on track. I'm pretty sure every wheel will eventually crack with regular track use unless you are slow. Are carbon wheels used in pro racing? i'd be curious to know what a normal life span is on them in that environment....
Either way, I do expect wheels to fail eventually from track use, but not in the window of use my car has seen. High-end, lightweight forged aluminum wheels should last several seasons of heavy use, and the CF wheels should be even more durable because it does not have the bending fatigue that aluminum does.
