NarrowerTires?
I have an '09 Focus that is giving pretty good FE. The tires on it are in good shape with only ~22k miles. It will be awhile before I need to look for new shoes but in thinking of ways to improve economy, I was thinking of switching out to some narrower tires when the time comes.
The stock tires are a 195/60-15. I found a 155/80-15 that looks to be within 2% of the stock diameter so it should work without effecting gearing or the odometer/speedo. The only negatives I can think of is the ride will be harsher and to avoid cornering at high speed with the effective higher profile to width ratio. In the realm of safety, seems like it should be fine?
Any thoughts or advice on what I may be missing?
