Well if you have ever had your tires rotated at a dealer/ shop you can forget about the torque ratings for the lug nuts. My experience is that they use impact wrenches and the torque is way more than spec. Often it is almost double spec. Lug nuts on my fiver are supposed to be torqued to 120 lbs. When I had a blowout one of the lug nuts was almost impossible to remove with the t lug wrench. I had to use almost all of my 230 lb weight to push down and all my strength to pull up on the other side. I will guaranty it was torqued to over 250. Point is, get way more than you think you need unless you do all your own tire changing with a torque wrench. Good luck.
