I cannot make up my mind on which tyres to put on my tourer. Winter, summer all season... There's so much choice these days and with the new efficiency ratings displayed, even more things to fret about. So do I just stick with what I started with, or is there something better Michelin HP primacy were originally fitted. I've got two continental on the front now and the two original Michelin on the rear which have done 86000 kilometres. Anybody got a view out there?
