Good idea, since you are allowing 1" wider fenders. It would be nice to be able to use tire widths up to 10.9" in PCA Prepared. The 275/40/17 (10.3"), P295/35ZR17 (10.8"), P275/35ZR18 (10.3") or P285/30ZR18 (10.9") in the PCA Prepared Classes.

You're right Larry it was 2750 in 2009 and the 2010 rules have not been finalized, so the 2700 is speculation at this point. The weights in my response were only used in reference to the original question regarding wheel widths. Tim the simple answer is 8's and 9's in stock and 9's and 10's in prepared for a 944 under the PCA preparation rules. |

Consideration is being given to allow a bit wider tire for Cup class Prepared as we allow fender flares for wider wheels and tires. |

Look for a 10.3 inch wide tire per manufacturer specs. |

DD - looking to collate tire specs as some of these came over from the old forums and have superceded the PDF rules As I understand it - for Cup class 1) Cars must run DOT approved tires 2) Max width is 10.3 inches per manufacturers spec 3 944 Spec cars must run the Toyo RA1 or R888 in the approved size - 225/50/15 Have I missed anything? Thanks! Matt |
