If you can tell us the make and model we can do wonders for you. In general either reduce load or increase rpms. Maybe inflate the tires another ten psi? Under drive pulley for the accessories? Turn off the AC? Check for vacuum leaks, do a general tune up.

My example with my sidekick seems to like to be around 3 thousand rpms. Since going up 3 tire sizes I find situations where I need to go from 5th to 4th where as I use to leave it in 5th. The benefits of the bigger tires well out weigh that issue.
