tallest LRR 14s i see on tirerack are 205/70-14 a 4.2% reduction ...which might be fine if you were 80% city instead of 80% hwy.
going to 15's a 205/70-15 would give you only a .4% reduction. 215/70-15 would be a 1.7% increase in either of the 15s you can get goodyear fuel max, mich defenders, mich x-ice, and yokohama avid ascend.
