Rim Sizing Question

[firesice18]

I am in the development stage for a new product and I really need some accurate assistance and figure this may be a great place to begin.

I really need for anyone, who is willing, to take a tape measure to your rims and measure the diameter of the rim to the outer edge and tell me the exact size, as well as, what the specification is (15", 16", 17", 18"?). Also, what year, make and model the rim is on for documentation.

This could GREATLY speed up the process on this new product. I can't say exactly what it is yet but with some assistance from this forum I can get there much MUCH faster!

Any help you can provide would be GREATLY appreciated. Thanks guys and girls.

You could do that yourself at a scrapyard.

Trust that I plan on it however the more data that I have the more accurate I can be. Thus the product is introduced faster...

It's a little unclear why you are trying to find this information, but here is something that should be extremely helpful:

http://www.barrystiretech.com/traflange.jpg

This is a page out of the Tire and Rim Association Yearbook. It deals with the rim contour for passenger car J type rims.

Notice that the dimension you are asking for is the D diameter + 35.0mm. In theory, any rim designed for passenger car tires should conform to that dimension.

That more or less answers the question that you asked, but there may be some other considerations if you are designing a product where that is a critical dimension - for example: The rim flexes under load, and the tire may have rim flange protectors that extend beyond the rim face. If the product may interfere with that, you may need more info than just the dimension requested.

My suggestions for capsel diameters:
Wheel size=diameter mm=diameter inch
15"=415mm=16.338"
16"=440mm=17.322"
17"=471mm=18.543
18"=495mm=19.488"
19"=520mm=20.472"
20"=545mm

Those are the dimensions which I got when I was measuring aluminium rims at local rim dealer. Tolerances in those dimensions are about +-1.5mm
