I bet the “engineering tolerance” of the studs is fairly wide though, as @flixden mentions, most tire-store “mechanics” have never seen or even know such a spec exists, or at least I’m inclined to agree with this as well, unless things have changed a LOT, at these stores.
I wonder if even the dealer gets out a torque-device, when they’re installing wheels; I sort of doubt it, they probably just grab a pneumatic wrench and zip-zip-zip, done.

The thing I worry/pay more attention to, is making sure the wheel is seated all-around (light torque) before “walking back forth” across the stud pattern up to spec (or good-and-tight), so that you don’t have >=1 loose studs (this can happen if you bring 1-2 up to torque first, and never re-tighten them, after the others). Personally, I’m more worried about this, than having them a bit over-tight.
