even if you get your gearing back what the equivalent of stock was, you will lose some mpgs...why? because you are still having to move MORE weight. You have to figure out your final drive ratio when stock, then recalculate it with your new tire height and gear ratio selection. Theres tons of calculators out there that let you compare stock gearing vs bigger tires and different gears. If I were swapping out gears, Id get something that would bump up my rpms a bit higher than what it wouldve been stock to compensate the extra weight....ie..if stock you did 2K RPM @ 65mph...Id go with some gear that would put me at 2500 RPM @ 65...thats just my opinion though.
