I am F.I. and dyno'd 223/207 @ 7400/3800 RPM and probably run closer to 235/215 day to day. I run 225/40/18 BFG Gforce Comp Sport 2s. These run very wide for a 225. I selected this way to keep the tires light and the costs low. I have plenty of grip for the street and my power levels. As many mentioned, tire compound will make a greater difference than width. PSS' will be even stickier than my BGFs, so these also would be fine at 225 if you manage similar torque numbers at the wheels to me (which you should @ 8 psi).
