Just a point of reference, but My 2015 had ProContact TX Continentals from the factory. They’re not conspicuously marketed as an eco tire, but I did notice on TireRack that they weigh the same 19lbs as the Ecopias. MY GoM was starting each day with 73 miles of range on an 80% charge. I’m much more satisfied with the ride, handling, and feel of the PureContact LS Continentals I just put on, but I’m seeing more like 68 miles on the GoM at 80% charge now. The PureContact LS IS an eco tire, but it weighs-in at a typical “anytire” 21lbs. Go figure. (I’m running the same 41psi I did on the TXs)
