I'm glad you posted it

...hopefully it will raise awareness so that everyone stays safe


Like Wayne, I thought it was obvious, but I can now see how a mistake could be made.

 

I guess these errors are happening. I grabbed a 1st Gen and a 2nd Gen OEM Sedan lug nut to show the difference. Might make it easier to differentiate the two.

 

good pics Wayne....

Just to carry this one step further;
The purpose of angle seat on the gen2 is only to guide the shank into the hole.
It is not a load bearing surface.
In those pics it looks like the angle is different too.

 

Seeing them side by side, again, can anybody explain why the nissan "shank" nuts have the same taper as the "conical" nuts, and how they seat differently? It almost looks like the shank could be used in place of the conical. [edit, posted at the same time as integr8r]

The only explaination I could think of is if the conical are hardened differently!

 

The taper angles don't look the same to me.

 

IDK...I taper angles look the same to me?

 

one other thing I noticed....

The lower edge of the cone is narrower/finer on the shank nut.
This would mean that it seats deeper into the wheel & likely less contact area.

 

Anoother very obvious thing. The 2nd gen lug nut tightens down on the wheel on top of that loose rotating washer. If you put it on a wheel not meant for it then this washer is left free to rattle around.

 

got me thinking, are the lugs the same for a 08 g35 and 08 g37 sport?

 

I could of told you huys this two years ago lol. When i installed my oem 18" g35 wheel locks on the m45 wheels, the wheel lock snapped clean in half, and the other lugs didnt seem to fit right. Thats how i learned they where different lug buts smh!

 

i have g37 19s that i plan on putting on my 2nd gen sedan soon. will my sedan lugnuts be ok for the g37 19s?

 

Safety Alert!


FWIW;
This is what can happen if you use the wrong lug nuts instead of the new OE shank style (see top OP pic).

.....tuner lugs ripped right through the wheel seats

So can someone post a link or a model number of exactly what is needed? I have over 25K miles on my M45 sport wheels and the guy at America's Tire (installers of wheels and tires) told me the lugs I had (from stock 17" wheels) were fine. Thanks for the help.

 

Anyone? 35K on the car and counting....gonna swing by Infiniti or Nissan on the way home from work.

 

any answers on this??
