My wheel setup and what tires size

I'm never going to run FI, even if (when) I put the car on a diet and give it a dose of steriods, because our class reg's on this side of the Pacific don;t permit it.

Indeed, if I stay in Production class, my maximum wheel size is only 9" x 18" and tyre choice is limited to R-Spec rather than full slicks.

I use "little" tyres so the CoG is lower without having to worry about suspension arm angles, and it helps with gearing - the effective final drive ratio with the 265 tyre is 3.92:1 and I don't have to open the diff housing ....

The old setup was 8.5 front with 245/40R18 and 9.5 rear with 275/35R18 and that was severely grip-limited at the front ... with 265 all round, is is "nicely balanced" and I don;t see the need to go 275 or 285 (although 285/30R18 will drop the car another 8mm and in theory improve mechanical grip and drop final drive to 4.02:1).

Is my name actually Fuller Schitt or does my logic have some basis in fact ???

They're limited because those are the sizes Grand Am would allow.
