When I had the ecopias tires, I got close to 90 mpg at 55 mph! Now it’s down to 60. A 30 mpg hit from a simple tire swap is brutal and doesn’t make sense to me
At 75 mph I was getting 55 plus give it take mpg
So low speed high way driving I drop from 90 to 60 mpg and then at fast interstate driving I only drop a little over 5 mpg
Might as well just drive fast since the numbers hit is so small
Can anyone explain this?

The difference in the weight of the tire can make a huge difference on economical vehicles, the ecopias are a very light tire as to where a snow tire my be at least ten pounds heavier.
