Front wheel stud length and thread engagement

[FortMacGuy]

I finally got my winter tires sorted out - good thing because winter just hit with a vengeance. It's -15 Celsius (5 F), scheduled to dip down to -20 Celsius tonight.
I got aftermarket wheels that fit fine, but the front wheel studs do not reach to the end of the tuner style lug nut. I measure about 3/4" of thread engagement. Rear wheel studs cover all the exposed threads on the tuner style lug nut. The wheel is tight to the vehicle and I can't find any major differences with OEM lug nut and tuner lug nut as far as internal thread length.

Does anyone see any issues with the front lug nuts? I think it's fine but it looks different...

If desired Gorilla makes extended thread lug nuts as do a couple of other aftermarket companies.

You need at least 7 full turns of thread engagement.

That doesn’t help the OPs situation of short studs due to different wheels.

Do not go by what what “looks“ right.

They have a collar that goes inside the rim well area to be able to catch on more threads. So it would help, so long as the holes in the rim are large enough for that collar to fit inside.

An example:

Yep, stud is short or at least it seems to be short visually.
If my math is correct I should have almost 10 threads of engagement from the base of the lug nut to the end of the thread (16 mm / 1.5 mm per thread).

I think I'm good but such an odd experience to see exposed lug nut threads..

Don’t go by “calculations”, take a nut off and screw it back on. Absolute minimum of 7 full turns.

Take one lugnut off, mark it and count the turns including the partial turn to properly torque it,

Good luck

Will count the threads in the morning.
It's dark and cold outside now. Tomorrow will just be cold but I'll be able to see what I'm doing.
Ford has 2 part numbers for the studs: ACPZ-1107-A and ACPZ-1107-C, while Dorman just use one part number to cover fronts and rears: 610-748.1 (single stud).
Ford never fails to surprise me in the most random ways.

It’s not unusual to have different lengths of exposed wheel studs front and back. My (F150) Raptor, my TRX and my new Bronco Raptor are different front and back...

I don't think the stud is the issue its the "tuner style" lug nut. When you order aftermarket wheels for a Bronco they don't ask if you need one pair for the front and a different pair for the rear with longer studs. The tuner lug nut isn't seating all the way in the aftermarket wheel correctly. A Ford Bronco wheel lug nut typically has a 60 degree taper angle. Some wheels may have a round ball seat or as Brian_B mentioned, a flat collar style showed above. Most after market wheels come with the correct lug nuts unless they require the same stock Ford lug nuts.

Great point about the lug nuts. I did buy a package tires/wheels/lug nuts/TPMS, all at the same time so I assume the lug nuts are correct for the wheels. You never know though - the store is one of a chain I normally avoid but they sell Nokian tires which are the best snow and ice tire I've ever run.
Link to the wheels I purchased. I cannot find any specs on the lug nut type so there's another reason to pull a wheel off and take a look.

Something is off...

Tuner lug nuts generally have a 60* seat like the stock accorn nuts however their outside diameter is smaller. Your wheels may require a 'Mag' style..

And, are you certain your wheels are lug centric for the Bronco?

The wheels you linked have the correct bolt pattern but the hub bore is listed at 108MM. I believe the correct bore size is 93.1 for the regular Broncos meaning they will not be correctly hub centric among other things..

Hub centric adaptor rings are available from uswheeladapters(.com)

Also, those tuner lug nuts just don’t look right in those holes, I have tuner lug nuts on my RTR wheels on my Bronco Raptor and they are much closer to the sides of the wholes, your lug nuts almost look lost in the large holes..
