After viewing a post on another site showing Carrera Sport wheels with 305 tires on a new C2S, I re-checked the P-car on-line configurator which confirmed that the Turbo option also comes with 305's. I was concerned enough to run back to the dealer (actually I drove) to find out why my '08 C2S w/Turbo wheels only had 295's. I was told that 305 tires are only put on the C4S, and that they wouldn't fit on the narrower C2S, even though you can still purchse the the Turbo (404) or Carrera Sport (XRR) option.
Now I'm really concerned, and will be very upset if I find out I was supposed to have the larger tires on my car.
My next step is to contact PCNA, and try to get an accurate answer. I'll keep you posted.
Are there any Forum Members out there who might be knowledgeable about this tire issue? Thanks.
