Just got Ecopias installed...

[NeilBlanchard]

I calibrate the odometer by driving a marked distance and then figure the multiplier to adjust the distance on the odometer. If you look at my fuel log for the xA, you see how I do it.

Even the "stock" sized tires don't guarantee the odometer is accurate. My summer tire (Nokian H) are oversized.

so are you getting better gaz mileage with the Eucopias???? I installed some a few weeks ago they had a special by three get one free, I needed tires anyways so the cost was just a little more then 4 normal tires would have been. I haven't been anywhere to test if I have gained anything.
