PCA yes it bumps you from Stock. SCCA no, any size tire that fits the stock wheel ( or a wheel the same dimensions +/- 6.5mm (1/4" offset from stock). I run 235s on the front my boxster that came with 225s so in PCA I'm in P14 but B stock in SCCA (or RTR in my case).

Thanks, that's the way I was reading the SCCA rules.
