So the 215s could be mounted on the 6” wide factory rims I have now with no problems except slightly lower fuel milage?When I had the 215s they were mounted on 7 inch wide 5 spoke alloy wheels. The previous year I had the stock Dunlops mounted on those same wheels. There was a noticeable difference in the look, definitely more aggressive with the 215s. That would be compounded on the skinny 6 inch Honda wheels. I believe @litz may even be running a similar setup on one of his cars. The fuel mileage took a hit by at least 2mpg on the highway, but I still averaged in the upper 30s that year. Since i'm back on 195s my mileage is 40+. Around town it didn't have as much impact.
