HELP - Lug Nuts (1 Viewer)

[NEFJ60]

Finishing up my lift and wanting to put on my new Eagle Alloy wheels. Had painted my stock lugs black in anticipation of that.... Can I even use these? Do I need different lugs for the Aluminum wheels? Can I use the stock lugs for a bit, or do I risk screwing up the wheels immediately if I put them on. I noticed they don't have a bunch of lug left showing when tightened down and will prob preplace anyway, but need to know if I can role my truck out of the garage tonight or not. Thanks for any "Quick" help.

By the way, 1987 FJ60.

I'm under the impression that most alloys use acorn style lug nuts and most steel wheels use tapered lug nuts. I am talking how the wheel is centered on the axle. Either you need wheels that are hubcentric or tapered to get the wheel centered.

In other words you have to look at the wheel.

This wheel is lug centric. American Alloy Series 100.

My Eagle Alloys Series 058 use a lug nut that looks like this:

Size 12x1.5. I believe it is a conical 60 degree

Did you need extended studs? Those look like my stock lugs, but I only get about 8 turns on my lug and not much shows do to the thickness of the wheel. Also, do you torque to a certain amount for the alloys? Thanks klinetime.

 

[klinetime574]

No on the extended studs. These are much different than a stock lug. I would really look at a 60 degree conical lug next to your stock ones.

I have to spin these on a good amount before final torque. 85 ft lbs is plenty on these. That's what the little booklet that came with the wheels I have says.

Post a picture of the wheel. Close ups of the holes.

my understanding is that they both take conical seat lugs but the seat designs are slightly different on steel vs aluminum. The Aluminum conical seats have a slight bulge so they seat better. I would check with the wheel manufacturer. Lug nuts are something I wouldn't mess with.

 

[NEFJ60]

Yeah, as far as I can tell they both have 60 degree conical seat. I'll call the manufacturer tomorrow and order up the proper lugs if they say mine aren't good enough. Murf, I agree that you don't want to mess with that.

Yours will probably be fine.

There is no variation in acorn style lug nut conical angles.
If you are getting 8 full 360* turns on your lugs when installing them, that is plenty of thread purchase to secure the wheel and not back off or strip.

There is no variation in acorn style lug nut conical angles.

Im not saying he cannot use the lug nuts he has from his steel wheels but there is a difference/variation in acorn nuts. It is called a bulge seat as seen below. It would depend if the manufacturer of the wheel he has recommends them for that particular wheel. I worked in a tire/wheel store many years ago and it was company policy to only use the bulge seat lugs on aluminum wheels for liability reasons. Here is a description of the lug from McGuard
Just playing it safe for the guy who asked a fair question.

I just learned something today: http://wheelprofessor.com/2009/02/20/tech-stuff-13-et-lug-nuts-what-are-they-and-why/

It appears to me that the "bulge" provides a larger uninterrupted seating area, that a straight cone lug may not. It also seems to serve the purpose of being able to use a smaller socket on deeper aluminum wheels where a larger tire iron head would either not fit in the machined hole or would scratch the rim.

Thanks for all the info, guys. I see that it isn't "dangerous" to use my lugs, but I'll prob upgrade for reasons mentioned above. The tire iron is pretty tough to use right now.
