Larger wheels will definitely reduce your highway RPM, but will also (likely) have larger rotating mass. I would imagine that, if you wanted to increase your overall diameter, you're likely better off going with taller tires and smaller rims, because metal weighs more than rubber. You'll probably come out ahead overall, but I'd suggest you keep in mind that your speedometer and odometer will read incorrectly if you go up or down in overall diameter.
