please help me for the information ASAP

the story is that I just obtained a new set of 20 inch running 5X108 and stud 12.5mm stud so I have to use the wheel adapter.


I found the 12.5mm lug nut is too small for X308 wheel hub stud and that I tried the 14mm nuts but it it biting the thread but I am not able to tie it up and lose.

I am so helpless and desperate for answer because my current set has to be ready for another Jag guy from the forums.please share any information

The part number for the stud is JZB100064, but I can't find a thread size for it.

 

The X308's use a 1/2"-20 thread on the lugs, not metric. A holdover from their old US involvement, which is why they are on the old Chevy 5 x 4.75 bolt pattern as well. You should be able to find the half-length nuts you'll need for the adapters at any auto parts store. Keep in mind that the X308 comes from the factory with "cannon" nuts (otherwise known as shank nuts), and that the adapters will probably require a tapered nut.

 

thank you and it was correct for use a 1/2"-20 nuts, I went crazy trying out all nuts and finally found the perfect one for perfect fit. I will load the wheel swap thread soon
