The difference between 80 and 85 lb-ft is negligible.  However some
shops use the big gun impact wrenches set to way more than 100 lb-ft
of torque...  Even if the wheels aren't damaged, if you were to get
a flat tire on the road, you won't be able to get your wheels off
with that wrench in your car's toolkit.
