Too much tire makes a car feel numb and heavier. I think this is one of those places where 'more is less'. I bought the stickest tire I was willing to pay for, in the stock size. Also, overall diameter affects ABS, PSM and overall gearing-if you change the FR/RR stagger you may trigger these devices. Bigger tires slow you down except when at steady state max cornering speeds-because they're heavier. Even on the street ( and that is what I'm talking about), I think tire/wheel weight matters more than trying to get every last 'G', especially on a Boxster which is engineered for agility and steady-state cornering.
Next year I'll be going ultra-light with 18 and 20LB wheels and 225/265(or 255) tires. My car will be more responsive and will react to bumps- from minute to large) better. It will also feel like it's overall weight has been reduced and it will accelerate and brake better. What's not to love? Sometimes bigger looks better though- to each his own.
