You might look into siping your tires and get the best of both worlds.
I can tell you from real-world experience that it's a good thing. The tires last a LOT longer, it's cheap (bargain with them - sometimes you can talk the tire guys into siping for free if you buy a set of 80,000 mile warranty tires, etc.), and I've gotten over 120,000 miles out of a single set of tires this way. I noticed about 1/2 MPG increase on that particular vehicle (EPA 26, real-world 36 hwy).
