So these are different than a typical aluminum sleeve/nut, these are plastic.... (see pic to refer to what I’m talking about). Typical torque for a metal valve stem nut/collar I have found is 35 inch lb (4 Nm). Have no idea what these require Bc they are plastic. The service rep was to busy to find out today; but, I’ll call again tomorrow. Was just curious if someone knew. I really also wanted to know in case Costco has no idea when they put these inside aftermarket wheels for snow tires
