Lug Nut Size?

I replaced my 2017 lug nuts with
West Coast Wheel Accessories from Discount Tire
WZ561314LS special p/n for Disc Tire. They only charged $55 for the nuts and rotated my tires.

I agree, these trucks ask for obnoxiously high torque specs. The first set of lug nuts I ordered I sent back, the threads didn’t look as though there was enough material in there to get them up to spec without striping them. Ordered Gorilla brand, what a difference!

I swapped out my lug nuts tonight. After inspecting the old lug nuts, my assessment is that the use of impact wrenches on the stainless covered stock lug nuts de-forms the stainless cover giving it a swelled appearance. I do not think there is any corrosion on these, just impact wrench hammering.

My second issue and the reason this all came up—never trust some mechanic who just uses an impact wrench to install your wheels. I know someone in this thread said it is set by the line pressure/calibrated, but I have much less faith in the accuracy of that after working in the auto industry most of my career. Especially when each car requires a different torque spec, I certainly didn’t see someone adjusting a regulator or the impact. Most importantly—After taking each lug nut off our truck tonight, some lug nuts almost spun off with no effort and some required a breaker bar. Absolutely no consistency. It is my truck—so keep your thoughts to yourself, but I did use my torque wrench on the install. They are all 150ft/lbs now and the 13/16” socket now fits.

Ya i call on that as well, because you need more pressure to take off than needed to put on.

Not saying it's a precise method, just saying that's what many do to save time at the tire shops.

I always torque mine by hand as well.

Here is a picture of one of the lug nuts—you can see how the corners/edges of the nut were pounded by the socket—probably a 12pt versus a 6pt socket.

Saving time is not necessarily following the recommended manufacturer’s procedure. If you want to learn what the costs of not following the OE procedures are, Google for “John Eagle $31.5M incorrect repair” on a Honda Fit. While it isn’t lug nuts, but it illustrates how a court views the OE procedures. Explaining to the judge I was saving time probably isn’t a good defense.
