Hold the horses!! You went from 185/60s to 195/60s correct?...i.e., taller tires. If so then your odometer is reading 2% too LOW. You need to multiply your odometer readings by 1.02 then divide by the gallons used. You're calculated FE in your log should go up not down. If the tire is taller, you travel further for every "mile" read by your odometer as compared to your old tires. Taller tires give you MORE effective overdrive which in most (not all) cases will increase your mileage. This is one major reason I'm going to taller tires next week.
