First time taking off the wheels for new tread. The lug nut pictured as B is what’s on the car. Is that the correct lug nut for the wheel or should it be the lug nut pictured as A ? Different shoulders/flang as I’m not sure which is stock for the rims.
Is bolt be the correct length? Seams about right as the hub of the wheel is fairly thick. I forgot to measure the bolts   |

Bolt A has the correct flange (ball seat cup) and needs to be 40 mm.
Bolt B is totally incorrect. Here is a more correct option. Factory bolts had 19 mm heads, these are 17mm. Attached thumbnail(s)
