I am going back to the 14x5.5 MX-3 wheels. I can't stand the hit in fuel economy that I have taken! I had a 48 mpg tank before I swapped and was keeping my average in the 47's easily, I even had multiple 50+ mpg trips. Since then my fuel economy has tanked. This tank is sitting at 45.2 right now, and it is a struggle to get a 50 mpg trip. I will say an easy 2 mpg hit, which hurts when you are so close to breaking that mythical 50 mark

Using a calculation of increasing 10% Crr equals a 1.1% reduction in fuel economy, it appears that I have gained a minimum of 40% Crr from swapping the wheels! I find that hard to believe... 3 pounds of extra wheel weight wouldn't be this detrimental though, and that is the only other thing that changed.

I am
