Looking to change the nexans out for some sort of all season tire. Usually run Continental DWS on my WRX, but it isnt available at costco. Would prefer there since they have their tire install package and im there ALL the time so ill actually get the rotations done. Installation package includes mounting, balance, nitrogen tire inflation, lifetime Rotation, lifetime Flat Repair, lifetime Inflation Checks, new rubber valve stem & Costco Wholesale's Road Hazard. Any recommendations? How much range are you going to lose by switching to non low rolling resist tires?
