I have 1921 coupe with demountable wheels just wondered what the wheel wrench # is and if I have the right size wheel nuts the wrench size on my car is 11/16 thanks Ross
Mine are 5/8. I don't know if other sizes were used.
I believe that 5/8 was standard. I use the box end of the spark plug wrench for the lug nuts. Also fits the head bolts.
5/8 here too. Is your car Canadian? They might be a different size. I don't know.
Mine is 5/8.
Canadian cars also had 5/8" nuts and I use the spark plug wrench box end on them too.

I have encountered some demountable wheels on which someone had used modern lug nuts. They had the rounded inner face and worked fine, but they were a larger wrench size -- maybe 11/16, I don't remember for sure.
