Maybe we are going to have to admit that we are stuck with poor and random mpg?
It will go up in the summer and some will proclaim running in did it, then it'll dip again in the winter. My best chance of increased mpg is ditching these sh!tty Bridgestones.
You'd think that now the VW emphasis on economy and safety (as always) would obligate them to be more selective about what tyres they put on e.g. lower rolling resistance tyres that have decent levels of grip - not much to ask on a £26k car, is it?
If a full set of 4 Michelin PS3s increased my mpg by 10% and lasted 20k miles, they'd contribute £270 towards their £400 costs (Costco costs taking into account the promotional fuel card). Would a pair on the fronts give most of the improvement of 4, seeing as the back 2 are being dragged?
