Spare tire rim lun nut hole size versus steel alloy wheel

Are the holes for the lug nuts in the spare tire supposed to be the same size as my steel alloy running wheels?

 

Huh? Steel Alloy? If you have the aluminum alloy wheels with the shank type lug nuts the holes are bigger in the alloy wheel. On the alloy's the shank goes thru the rim and the wheel is clamped to the hub by pressure from the flat washer on the rim (the lug nut does not bottom out). The holes in the spare are smaller diameter standard lug nut type conical holes. If you look at one of the shank type lug nuts you will see it has a conical end. This contacts the rim of the spare like a normal lug nut would. Looks funny as the lug nuts stick way out , but it works just fine and that is how it was designed.
