Something that occurs is that one could use thin section rims added to trail bike drum brake hubs, with the strength and width of the one, and the style of the other.

.. a few photos with quite strange, big and strong DIY wheels, used for gigantic quadricycles used on "kinetic sculptures" shows and simialr festivals.

Wheels are really big, but some ideas could be used for smaller wheels?

That is some KOOL stuff, and my faverate the wooden jigs,built a lot of stuff that way. Mighty big wheels,but i like the idea of tube spokes. Would be really stiff and stought,but plastic tires would be noisy.
The colapsed wheel,one looks like it had a wide center in it. ............Curt

Hello Curt,
You must be right - such wheels and tyres could be quite noisy!
I had something different in plan, as I am not good in welding and other machine-tool work, I could make wheels by a pair of plywood disks, with reinforcement of wooden spokes inside (or stronger polyurethane foam). Then, to add strong rubber/plastic pipe of 2" diameter as tyre over it. Then, pull on pipe wide bicycle tyre. It would look as original pneumatic tyre - I suppose that solid tyre shouldn’t be welcomed even satisfactory to me. Beside, pipe should have blocked air in it...

Real wooden wheels, in a style of veteran cars are beyond of my possibilities...

Maybe some new ideas, for simple, big and and cheap wheels shall appear here... It would be simpler to use smaller and fat wheel-barrow wheels that some people use, even for light airplanes. But, I do not like that style...



Ciao,
Zoran

Wheelbarrow tyres don't work for anything except carrying loads slowly. Light aircraft, perhaps, but how durable is the rubber, and what side loads are they made for?

Avon do the Speedmaster motorcycle tyre, but unfortunately no longer as a square section. Perhaps there are vintage sidecar tyres out there from other sources.

------------------------------
... on most of such wheels, tyres are with note "not for highway use"! Probably not for any speed and stronger cornering? Illegal on any street or raod. Wheels are different: metal or plastic, needle bearings or casette ball bearings, or plain bearings... There are variant with solid fat tyres... At least: to change tyre with one from scooter. Not for my taste anyway. Maybe to use wheel as hub for bigger spoked wheel? Still just to think about all that. For some time my ordinary MTB wheels 26" on HPV-qaudricycle - should be good (I hope so).

I cut the hubs out of lawn tractor wheels with keyway in them and cleaned them up on lathe,and sent them to Silverbear for his tadpole build. He then built flanges for spokes and welded them on. .............Curt

Hello Curt,
I will try to find some photos of that modification - sound quite good idea... For any reconstruction or DIY building of wheel for velocar, good starting point is to make, or to buy - proper hubs, with good axle and adequate bearings...

I still think about using my MTB 26” wheels with some modifications if necessary: to make them stronger and more resistant to side forces (anti-twisting reinforcements). Maybe to make additional flanges that will add new support to rims (by spokes)? Maybe to add new rim, that could be used for belt-transmission (or outside belt-brake) – with reinforcements to regular rim and connection to original or additional and bigger flanges... Maybe to install plywood-disk, as one Russian guy did... Still, just winter-thinking...

Ciao, Zoran
