Thinking of these for lighter wait and a better fuel economy as a result https://goo.gl/uX2ryd

I would have paid extra for Enkei RPF1, which are even lighter, but they are 7" wide. I don't think I want to run such wide tires. I would have preferred to stay with the original 165/65/14 for lesser rolling resistance. Not sure if 165s can be installed on 6" Kosei wheel. Do I need to go wider?
