Today I mounted the winter tyres just in time. I directly used the new wheel screws with separate cone seat (there was once a SI/ swap action). The new wheel screws are especially aimed at those who switch between aluminium and steel rims. This is the case with me with the winter tires (15” on steel rims for the winter and the Anni 16” aluminums in the summer). With the steel rims, the wheel screws only have contact with the rims at a small point and this rubs with At the new wheel bolts the cone seat no longer turns, only the screw turns. When the old wheel screws were loosened, at least 3 screws were much looser than the other wheel screws. The old screws flown immediately into the scrap metal bucket without comment. All screws are tightened with my torque wrench and a wild mechanic with impact wrench on full throttle I do not let me approach the car. People look at the wheel screws when changing tyres or switch to the new wheel screws with a rotating cone seat.
