I bought these wheels in the summer which I've still not fit on the truck they are 8x16 et0. Going to go with stock tyre size but the question is which wheel nuts do I need. The stock nuts have a washer (not sure why) but when I've tried them on the wheel they don't appear to fit the washer part seems to be too wide as the nut doesn't seat in the taper or at least it feels that way. Do I also need new nuts and which ones?? Pics for reference:
