Dude where do you get your info. Costco doesn't torque tires? They\ninstall the lugs with a torque limited impact gun (limited to about 50\nfoot-lbs) so they don't overtighten them. THEN they torque them to\nmanufact spec WITH TORQUE WRENCHES that the calibration is checked\nMONTHLY. I can't speak for WalMart or any other outlets but get your\ninfo straight before you spread your "wisdom".
