Is this lug nut and rim taper wear normal

I've noticed that my tapers on the rim are a little ground down from the nuts. Should I be concerned or is this normal? I usually torque the wheels.

Hello, I'm Danny.

I would definitely check quite often. Usually that happens from incorrect torque or incorrect lug nuts. Keep monitoring to make sure the lug nuts don't loosen and have an opportunity to lose the wheel assembly while driving. Hope this helps and thanks for using 2CarPros.

Good morning,

Just to throw in my 2 cents, I do not like the rim at all. The holes are damaged from either the wrong lug nuts or loose lug nuts.

Saying that I would replace the studs, nuts, and the wheel. The lug nuts look to be too deep. I am thinking that the lug nuts are bottoming out and the wheel is not tight.

These are the factory lug nuts and steel rims. I first noticed about two years ago these tapers on the lug nuts. I put 4 Dorman wheel nuts on the other side for comparison, and none of them have a taper. The front two wheels are okay with the taper. It's only the left rear tire I noticed gouged a little from the lug nuts. I believe it's because one stud is a little stripped, and the metal shavings get caught in the taper.

That would make sense.

I would replace the studs, lugs and the wheel as I suggested.

Hello again.

One thing you might want to try is put the left rear rim and tire-the gouged one on and torque to specification you have in the past. Raise the tire off the ground and see if there is any movement-play. If it does you will know if there excessive gouging or the wrong-excessively damaged lug nuts. Hope this helps and thanks again for using 2CarPros.
