Not sure how it happened, but the last picture should be #5 I think.
I've had this figured out for some time now, but thought I'd pass it along. My monster truck bank is loosely based on Grave Digger, the only monster truck I actually like. For those not familiar with monster trucks, I posted a couple pictures of Grave Digger, and you now know why they are called monster trucks.
I wanted treads on my tires, but simpler than Grave Diggers, so did some research, so I didn't end up reinventing the wheel. Ha. Came up with some nice examples, but too bothersome and time consuming for me. Even found out that some people cut each wheel separately, and sanded them round. I wouldn't do that, even on a one only project. Couple of the wheels I found posted below. Those were formed by making each side separately, then gluing them together. Found various instructions for doing this, none of which appealed to me. I'm not making a scale model, I'm making a bank, so doesn't matter if the wheels are not quite real looking.

And here are a couple of how tos on making round wheels. Which also did not appeal to me. How to Make a Router Circle Cutting Jig: 8 Steps (with Pictures) Perfect Circle Using Drillpress: 7 Steps
I will be making my round wheels, by gluing the diagram on my wood. May be a bit difficult to view because I had to take it with my camera. Used a compass to draw a circle on 1/4" graph paper. Then laid a ruler down, centering on the point left by the compass. Then proceeded to divide the circle in equal divisions. I will drill a 1/4" or so hole in the very center, rough cut the outside circle, which will be 9 1/4", the size of the largest truck wheel. Wheel sizes will be from 2 5/8" to 9 1/4". I'll clamp the bolt in the hole, held tight by a nut, then spin the rough cut against my portable belt sander (still need to make a stand to hold the sander), which will give me a nice perfectly round disc. Picture below. What you likely cannot tell from that circle pattern is, each line will be where I will rout a small cut, to make my treads. Real rough sketch below showing what I mean. I'll need to cobble a fence, just a chunk of wood, with a notch for the router bit, and clamped in place. Each line on the disc will then be lined up with the bit, and a notch of about 1/4" made, until all lines are notched, evenly.
OK, that will give me the first step in my actual master. The notched disc will be nailed to another piece of 1/2" plywood, rough cut to just over 9 1/4", then routed. This will give two discs, exactly the same, and notched for tread. The disc without the paper glued to it will then have the center cut out with a hole saw, varying sizes, depending on the size of the wheel, using the small center hole for a guide for the hole saw bit. This 'finished' piece will then be glued to another rough cut piece of plywood, which will be routed, using the top pieces as a guide. And the finished piece will be a 1" thick master, to let me clone treaded discs all day long. Actually, I will nail the master on a rough piece, rout that, including the center, to get a wheel look. That piece will then be glued on to another rough cut piece, and routed, except not the center this time. Repeat gluing on, and routing, until I get the desired width (1/2" increments) of that size wheel. This will give a tread pattern similar to the vehicle picture below.
Then it's bolt back in, mark the next size smaller wheel I want, back in the drill, and sand it down to size. Then it's a repeat of above, just with a smaller wheel. Repeat until all of the masters are done. This will give me accurate size wheels time after time. Easy peasy. Don' need no steenkin' CNC.
