Well the first new tyre tank result is in - from 54 MPG to 74 MPG.... obviously, a few more tanks are needed to get the full result. My 57 MPG tank was nearly all on the old tyres, apart from 50 miles, but it turned out the tyre pressures were down (straight out of the tyre place, 31 and 34 psi, sloppy...).
So, the 54 MPG result was half motorway miles at 56 MPH and the rest my rural and hilly commute. My 74 MPG result was about one third motorway, a third my commute and a third other rural roads.
I think I'll stick 2 more Bluresponses on the back end, despite a good tread left on 'em....! They are A rated for braking in the wet, and they are equal if not better than the Hankooks they've replaced for handling.
