Discount tire and using the locating lug nut

[KBalzuweit]

I was planning on going to scheids tommorow. But thanks to Discount Tire thats not going to happen. I made the appointment for a rotate and balance and after 2 hours plus (at 5pm) I got my truck back. Jump on the highway and it shook so bad my teeth hurt. Went back so they could try it again, this time I watched. They knew nothing about using the 2 cone lugnuts for centering. They looked at me like I was nuts, the manager said there is no such thing. The bad was my dually which I bought last week did not have any in it and they did not either. So I drove home 20 miles chattering my teeth. Atleat I got my money back. Now in the AM I have to go find some and do the job myself.



After I got home I got out the owners manual and there it was. I just wish I would of thought of that and showed it to them.

Karl,



I went to the dealer in town and they have never heard of this. Do you have a source for locating this type of lugnut?

The TSB you are looking for is # 22-01-91a (may be superceded by 22-02-92) and the 90 degree cone nut P/N is 1273556 and can be ordered through your local dealer.

I just went to napa and got a few 5/8 x 18 cone lugnuts. They worked fine and are about $1 each.

I don't have any of these nuts for my dually. My hubs are countersunk to accommodate the alternating coined shapes of the original rims. Don't the shapes that make the rims interlock also fit a corresponding shape on the hub? I have had to make some centering devices somewhat like you described to center some of the rims that are currently on the truck, though. When I bought it, it had (and still does) a mixture of three types of rims. This happened because the previous owners pulled a trailer that used the same size rims and tires and they ultimately mixed them. The results weren't so good when they mixed coined Dodge rims with flat-flange rims on the same hub. Some slippage resulted and holes became elongated . I use the tapered nuts that I made to center the flat-flange rims before I install the lugnuts. I'll get rid of the odd-ball rims when I wear out the tires. I have a set of original rims that I'll put on when that time comes. So the original rims are not centered well enough through the coined surfaces ?

Correct!

I found the centering lugnuts and my question is this; can I get enough to put the coned lugnuts on and keep them in place, or do I have to remove them after the 4 flat ones are installed and run flat ones all around?

 

[Paychk]

The TSB says to re-install the regular dully lug nuts after the rims are centered, I don't know if it will be a problem or not. You could try it for a while and check them occasionally to see if any thing comes up.

If you will look on the bottom side of a dually lug nut you will see the lug nut does not center off the coins. The bottom side is recessed to miss the coins on the rims. It does tighten up on the flat section of the rim.

lugnuts

Let me share some experience on the cone style nut. The 350, 1970 Ford that I drove for twenty years had cone nuts all around. Factory installed. After a few years of heavy loads and hard miles, the fronts began to break the lugs off. I went through this for a number of years and when Ford came out with the footed washer that they still use, I changed my lug nuts to that style.



These are diffrent from the Dodge design which has the foot made integeral on the nut. The Ford nut has a foot that will turn which is spring steel. The net result is a fastner that will hold at a lower torque than the Dodge. My experience was completely satisfactory with the new style ford nut. I used two cone nuts (always in place) to center the wheel. I never broke another lug. I can also tell you that it will work fine to have a couple of cone nuts installed all the time on each wheel. Then even the least experienced tire shop employee will see that there is something that must be used to locate the wheel.



There is no Ford style nut available to fit our stud size. If there were, we could use them to good advantage on our trucks. The NAPA store here has the cone nut.



To anyone running mismatched (coined and flat) duals, this is a serious no no that will always lead to failure. You can get by with running two flat wheels on a hub that was meant for coined wheels, although you may have a balance problem.

Thanks for that, James. I ended up getting mine at Advance Auto Parts. I did have to talk them through the search, but they were there. Been using since this thread started. Have not been keeping 2 on at all times, but will start. It gets REAL old trying to explain the process to tires shop kids. Also, I have to back off 2 of them anyway, to put my wheel simulators on.
