And If you really have read the tire threads, you would see that a taller tire (up to a limit) is actually HIGHLY recommended.
I will be in the boat for new tires, the vic currently has I believe 215/60/15(don't quote me) on right now. So the suggestion would be to go to a 215/65/15 or possibly a 215/70/15? would changing the width to a 205 or a 195 make a difference?

As a side note, would lowering the car offset the height difference?(edit:duh, what i meant to ask was; would the combination of lowering the car an inch in combination with increasing the tire diameter prove favorable mpg wise?) the car has plenty ground clearance and could afford to hug the road a little more.
