I just bought a set of the six spoke rims from a smashed up 81 for my 260. I went to nissan and bought the correct lug nuts for them. I go to the seccond rim and only three lug nuts go on. on the las hole the nut wont fit in the hole . i have tried the other nuts but the all dont fit. I have no idea what is going on? Does anyone know what is goin on???

Thanks

 

They are aluminum. The wheel could be warped but most likely there is just damage or some flaw on or near the hole. You can probably just shave the inside of the lug hole with a round file untill the lug nut fits in there.
I used to have rims like that and they would often get stuck on the threads of the bolts when trying to remove the wheels. It seems to be fairly soft aluminum; although they are hard enough to polish.
