I don’t recall where, but I originally saw this technique using the tank treads on Flickr or the like. I started working with the technique but found it too flimsy and not well suited to place a top or bottom connection on a MOC. After a little tinkering, I found a good way to strengthen the internals of the build and allow connection points on the top and the bottom. Once again, I did not invent some of this technique, I merely made an improvement on it.
First things first- we are going to need four wheels of this size.

Next we are going to need some of the large tank treat. The right amount to wrap around a wheel is 9 links. Since we have four wheels to cover, that means we need 36 links total.

After wrapping both wheels with tread, I place them on an axel so they are off set by half a tread link. This means the center of one tread link is right in the space between two treads on the other wheel.

Next I add the half Technic pins so I can start connecting Technic beams.

Then I add a layer of Technic beams on the treads. Ignore the extra half pins that are sticking out in the photo, I didn’t remove them from a prior project before sticking them in here. There will be a SECOND layer of Technic beams, so the half pins should NOT be in there.

If I want a taller tower, I repeat the same steps to make a second super structure cylinder and connect them with a Technic axel. Here is where the other two wheels and 18 links of tread are used.

Next I add a second layer of Technic beams and place some half pins in the beams so I can also add two layers of single width plates. Notice in this picture I have the two layers of Technic beams and on five of the spokes I also have added my layers of plates.

After adding the plate layers, I can add the tiles to complete the look.

There we have it, a round tower with a connection point in the form of a Technic axel on the top and bottom
And the resulting tower...
