lug nut help.

[SUPERSUB87]

i know this is kind of broad... but im having a problem with the lug nuts i need to order. the bolt pattern is 8x6.5 and the bs is 4.5. to the measure of the nut is 5/8 i think or 9/16. idk. so what exactly should i be measuring? like diameter and such.

wheel stud diameter of the threads, length of the exposed stud with the wheels on, and type of seat. Cone for most steel wheels like stock, or a shank type lugnut which would go through the wheel. If a shank type measure the diameter of the lug opening in the wheel.
