I've been building wheels.

It started when I saw the foam cushion thing my daughter had bought for next to nothing. It looked like the perfect thing to provide me with some largish wheels I need.
Having bought my cushion I used a hole saw to cut some tyres, and a smaller hole saw to chew out some washers from an oil bottle.
I also grabbed some Nylon screws and nuts to form the hubs.
The procedure went something like this.
Thread the washers on to one of the screws with a wood backing plate and clean up the washers in the toy lathe.
Assemble the tyre with a washer either side on to a Nylon screw and tighten a nut on to it.
Insert the Nylon screw into the lathe chuck and sand the tyre to size and shape. I used an open weave sander and It was fast and easy.
Turn half the thickness off the screw head and make the center hole. I used a 3mm drill for this.
Trim off the spare Nylon screw and the job is done although I will lock the nut in place, probably with a touch or three with a hot iron.
The 55mm wheels shown here weigh 5 grams each and I have some 65mm ones weighing just 1 gram more.
I want nice forgiving wheels for my FPV planes and I think these will be the goods.

Hubcaps ?

For the finishing touch, how about some hubcaps ?

I used some hard foam from a kneeling pad, (used when kneeling in the garden, praying the weeds wouldn't come back ).

The hubs were commercial models plane wheels but with very heavy plastic tires.

The 'hubcaps' are cut from the bottom of a drinks can, nicely ready domed, and fixed on with a small dab of contact adhesive.

That's a great idea, Ray.
I'd certainly need to do something like that if I was building the nice scale looking planes that you do so well.
The bigger wheels are for an FPV plane that has a very Unmanned Aerial Vehicle look, so the clunky hex hub will be OK.
The smaller ones are intended for a sports aerobatic thing I've had under construction for some time. It will need some hub caps I'm (now) thinking.

Nylon screws from Bunnings. Washers from any suitable scrap.

Ray's post has made me think. His posts often work like that.
With the method I have outlined you are left with a cut off length of threaded Nylon.
What about if we made the washers from thicker stock (say 3 mm) and tapped them so they would screw on this threaded shaft meaning the bolt head and nut are not required.
You could even drill (sorta) scale-like holes in the washers or even turn in some other 'scale' details

Go to your local sporting goods store, or possibly even big box department store and look for a seat cushion. Or, go to the gardening department an look for a kneeling pad. Either of those should get you what we need.

These look fantastic!

If you want to go super cheap and you're ok with the dayglow colors, these are from Dollar Tree: https://www.dollartree.com/Garden-Co...8408/index.pro
