I'm looking at some new tyres for an SR+, any feedback on the ePrimacy tyres after a few months?
I think the ePrimacy are fine. Possibly a little quieter than the Pilot Sport but hard to tell. Certainly no noisier. Cannot tell any difference in grip.
Only done 3,200km with the ePrimacy. Cannot see any difference in efficiency when compared with 2,365 drives logged in Teslafi. You can dice and slice the drive database many ways. I think there are too many variables to definitively determine the efficiency this way, having only driven 3200km on them. You would really need two identical cars side by side driven the same, both fitted with new sets of tyres. As far as I can tell the Wh/km is the same for ePrimacy as for Pilot sport. For how and where I drive 170 Wh/km.
