Wheel sizes?

[sloperlad]

I was trolling through the web trying to learn more about the 38 special and have come across some information that I find conflicting. My vehicle is an Australian assembled model and has 16 inch tyres. On some sites 15 inch has been the size fitted. Are the Australian and American cars running different sizing?  I would have thought they were the same. Heads up I am new to this owning a classic if this vintage and still learning. 

Cheers in advance.

In the ‘39s, the Specials have 16” wheels and I think all the other models have 15”.  Should find the answer in the Service Manual for the year car you have.

for 1938, Buick Judging manual shows 15 inch for 60 series and 16 inch for all others.
