Wow, even the guy at NAPA thought they were crazy. And this is a well-known, pardon me, the best known shop in town (it's a small town of 11,000), has a great reputation. Cheapest in town to dismount tires, mount and balance, $72. Cheap doesn't always mean best! I thought, this is easy. Any tire shop should know this. Or at least look it up. Of course, I brought the wheels in. Saved $120 or more doing that... Thanks guys...
