Cracked wheel, blew out tire, need Replica Carrera ASAP

[Perfectlap]

Not a good night on the highway. Tire went flat and sidewall was compltely shredded on the inward side. Get out of the car, lug wrench is not in the kit (DOH!).
Call my buddy for help who happens to live nearby... microphone on cell phone is dead (DOH x 2). By the way it is 18 degrees and windy as heck. A kind motorist stops in his SUV and has a lug wrench to offer. I remove the old tire and the inside wall is shreded.

I just ordered a replacement tire from the TireRack ($240..ouch) but the 18" factory Carrera wheel is cracked, about an 1-1/4" long. Source of the tire failure?
Must be. I need to find a replacement preferably a replica wheel but I'm not seeing any on Wheel Dynamics.

Any site recommendations? Buying only 1 used wheel is obviously going to be hard to find and for the price of a factory wheel ($600) its not worth it as I plan to upgrade the wheels soon, they're all pretty banged up.
