Got my new A/S Michelins installed at Costco yesterday. It was raining when I collected my car, so hopped in quick. Got home, looked at the tires, and noticed they've got the bright green I-BELIEVE-THE-NITROGEN-HYPE-AND-I'M-AN-IDIOT valve caps. I didn't pay "extra" for the nitrogen - it's just what Costco puts in everyone's tires.
Needless to say, I will be asking for four black ones when I go back for the 40 km torque check.
