Anyone see a MPG drop going from 35's to 37's

Well I need to get new wheels and 2 new tires at the least. I was thinking of just getting the moto metal 951's black/chrome and 2 new BFG tires. I was also thinking if the MPG were not really affected then I should jump up to 17" wheels with 37" Toyo M/T. Let me know what you think!

Yes if you stick with the stock gearing you will see a significant drop in MPG's going from 35s to 37s. However if you regear to 4.30's you will regain that loss
