I have been asked by a client if I can do this.
They want a rendered image that is: 175200 pixels x 16200 pixels. 146 ft. x 13.5 ft @ 100 DPI.
I know C4D has a limit of 16000 x 16000 pixels
Can I render this in C4D with the tiled camera? @ 5x5 grid?
If I can, how do I set this up?
My mind is going... the math is driving me crazy, any help would be greatly appreciated.

I don't see how you'd be able to get past the parallax issue if you moved the camera. You'd have to keep the same position for the camera and simply rotate the camera to pan through the scene. Then stitch the images back together... and still you'd have that fisheye look you get in spherical panoramics.
My suggestion is to do the render as high as you can and use something like genuine fractals ( http://www.ononesoftware.com/detail.php?prodLine_id=2 ) to blow it up the rest of the way. i.e. (16,000 x 1,480) x 11. I rounded those numbers of course.
Maybe Maxwell or Vray don't have the res restrictions that C4D does? If that's a doable option for you.

If you render your scene at half of what you need the final, but at a higher DPI, like 200 or 300 DPI, you could then open the render in Photoshop and size it up to your final resolution without the DPI dropping below 100 DPI.
Just make sure to turn off the "resample image" setting within the image size dialog in Photoshop when you scale up.

Thanks, Jonathan and Tony for responding!
Can you tell me in C4D how the 16000 pixel limit and the DPI option works?
How the pixel count and DPI relate to each other?
An example would be: in PhotoShop when you have a set pixels at 3000@100 DPI and you change the DPI to 300 the pixel count goes up. How does this relate in C4D?
Just trying to understand if they are independent of each other?

Let me see if I can explain it for you, in a way it doesn't even make sense to me since the resolution dimensions in C4D are in pixels and then you are given the option of adding more in DPI or PPI, dots or pixels per inch.
If you render an image in C4D at 800x600 in 600 DPI, then open it in photoshop and enlarge to 1600x1200 with resampling off, the image would then be 300 dpi at 1600x1200.
If you just increase the DPI in photoshop to, lets say 300dpi on an image that was rendered at 72 dpi (screen resolution), you are increasing the resolution by interpolating and will get a poor result. Doing so in this way, the computer is sort of "guessing" what the added pixels should be. You can experiment on your own to see the results.

Not to throw another wrench into your gears, but do you have the computer power to even render an image that large? I regularly max out our 2x dual core Intel Macs (8gigs RAM) when just attempting 8K film frames. I can't imagine rendering something twice that size.
