Just got some new wheels for my insight, and thought I would post some pics for anyone interested. I went with a 15" wheel, and some 195/50 R15 Falken tires. The overall diameter of the tire is virtually unchanged, but the new tire is 1.2 inches wider than stock. I hated the stock potenzas. They were predictably unpredictable on wet roads, and would break loose without warning. I've driven about 800 miles since having the new tires/wheels installed my previous average MPG was 61.8, and so far I am averaging 60 MPG. There is a noticable difference on the freeway. I find that I have to work considerably harder to maintain speed when conditions are less than ideal at 75, but for the most part 65 is not a problem. The car feels glued to the road with the new tires, and best of all I don't have to turn my radio up as loud when I'm on the highway because they are much quieter.
