i dont think its quite as straight forward, larger diameter tires also increases ride height, so your gearing gains can be washed out by the additional aero drag.
also depends on how its driven. i'm thinking about going to a smaller diameter tire, but i've been spending alot of time going slower than i can get lockup in top gear, and getting jammed up in traffic.
