Look, dude. The impact of varying tire sizes on gearing is insignificant, about 2% at the very most. I have several FG bikes with gearing that varies from about 71 to 75 GI, and I truly cannot feel the difference. Far more important is how I am feeling that day, the wind conditions, the road surfaces I'm riding, the tire pressure and quality of the tire, the degree of foot retention, the riding position etc.
Tire size should be based on rider weight, road conditions and intended usage.
