WANT 2 BUY ONE 15X6 BUICK ROADMASTER WHEEL

[Dynaflash8]

I AM LOOKING FOR ONE WHEEL FROM A 1941-1959 BUICK ROADMASTER SERIES 70.  It is to fit my 1941 Buick Roadmaster.  PREFER HUBCAP CLIPS, BUT NOT NECESSARY.  I DO NOT WANT A 15X6.5 WHEEL.  I don't know what they fit, but that begets the question, how do you measure the wheel?  Or, better yet, how did Buick measure their wheel width?  According to the Buick Master Parts books (1947-1953 and 1960) the same 15-inch wheel fits all of the Roadmasters (and Century's through 1942, as well as short wheelbase 1941-42 Specials).  The book says they measure 6-inches wide, i.e. 15x6.  My mechanic says the machine measured four of my wheels as 6.00 inches wide outer edge to outer edge.  That would have been using that plastic thing they use when spin balancing.  One measured 8-inches wide.  Go figure.  Buick changed the tire size in 1947 or 1948, but apparently not the wheel size.  I always have heard 1941-42 wheels were different, but according to the parts book not thinner or wider.  The 16-inch tires on the 40-50 series were 6.5-inches wide.  So based on that, I am now just looking for a 15-inch Buick wheel 6.00 inches wide edge to edge, if there is really such a thing.  I know the wheels on my car are not 1941 wheels, but as of now the only difference I could determine was that original 1941 and I guess 1942 wheels only had three clips.  If anybody has a decent 15x6 wheel I need one, preferably with clips, but clips are available and I have two or three on the shelf myself.

Here is one I pulled from a 1949 Buick. Hollander interchange shows it to be the same as a 1948. Private message sent.

I though when I edited this, it would go to the top.  Maybe it will now.  Earl

Here is a link that gives answers to most of your questions.......It is not specific to Buick but when you understand where to measure, the Buick experts will supply the numbers.

Thanks Barney.  The only problem is, after going there, is that I'm not smart enough, or mechanical enough, to figure out what they are saying.  If you look above at Auburn's message to me with pictures, I see a 6.5 inch rim.  Am I missing something?

Earl,

 

Look closely near the top of the page on that link. It shows that the rim width is measured inside the top of the wheel. That would indicate that the one that he posted in the photo above is a 6 inch wheel. I may have an extra 15 inch wheel from my 1938 Century project since I bought 2 extra ones. I will have to check the size tomorrow and I need to do some more checking before I consider selling one. I am not sure if they would be the same size as what you need or not.

 

Are you looking for one to put on the ground, or a spare? I would consider one that does not look quite as good cosmetically to be appropriate for a spare, but I want to make sure that I have a good looking set of 4 for my Century.

Matt:  The '38 wheel is different width I think, but nevertheless I know the hubcaps will not interchange.  I'm going back to look at those pictures again.  All I know is that the spin balancer has that plastic measuring thing they put over the top of the wheel.  He insists the wheel was 6 inches as it was supposed to be and the spare was 8 inches (that makes no sense to me in the parts book.  One of the early books shows 7.00x15, but I think that was the tire size.  It's very confusing.
