Not enough info, hitmon. Are the tires or wheels wider than the ones you were running before? Is the compound or tread design more aggressive than before? Did you change the pressure?

I'm not sure that lighter wheels/tires make much difference to MPG; handling I can believe, but I'm out on MPG difference.

I ran the stock junk tires out (that didn't take long), and bought Hankook mileage tires (not my original choice). Not much difference in handling or mileage once I took the pressure up a few pounds, and they do seem to be wearing much better.

Lots of variables that will change your fuel mileage drastically! Wide wheels eat gasoline, as do wide tires, soft compounds, and tread design. It takes gasoline to push wide, soft, noisy tires, simple as that...
