Same thing happened a few years ago when I put new tires on my Olds Aurora. (And honestly, it happens to almost every car I've ever swapped tires on -- the Aurora just had the biggest drop in MPG.)
You probably do what I do -- you put on better, stickier tires, right? Maybe even wider ones?
You increased your rolling resistance. Amazing how such a little change adds up, eh?
