I have 4" with 35's, highway mileage isn't too bad. Stop and go will kill you though. It's a worthy compromise you'll enjoy. I just picked up a flashpaq to play with. Gained some mileage back but still tweaking the programs.

I don't know 100% sure I never ran 33's, but you'll maybe get 1-2more MPG due to less wind resistance and weight. 33's are better for a DD that doesn't do a large amount of wheeling IMO. My 08 is more of a toy that I take to work ever few weeks.
