Don't forget to adjust your fuel economy calcs if the new tire size is larger. Otherwise your gains may "disappear" from apparently less distance travelled.
No. The current winter tires aee of a soft compound and realy grippy in the snow. So i hope there is a noticable difference.

And that is a good idea to change it. But is only use my sg2 for the temps, rpm and an indication as to how my fe is. I drive over 1400 kilometer a week now. So the most accurate way is to do it at the pump. But i can notice that the pumps i used have altered their systems. And give less that on the dails.
