Small Pneumatic Wheels

[SndMndBdy]

Hi,

Does anyone know of a place to purchase small pneumatic wheels? I'm looking for something in the 4" - 5" OD range. Smaller would probably be OK too. I ultimately just need an inner and tire (not the hub), but a complete wheel would be fine as well.

Thanks!

I wasn't sure if they were avialable, then I thought about R/C airplanes that sometimes have small pneumatics. Here's one link (https://www.motionrc.com/products/dubro-big-inflatable-wheels-4-2-pack?utm_medium=cpc&utm_source=googlepla&variant=19071743046&gclid=Cj0KEQjw17i7BRC7toz5g5DM0tsBEiQAIt7nLD-HA6mwY0p54IuE5X9y46eHsSGBrKMvrSG6NiDHWSwaAt3r8P8HA Q) I found. Try adding a combination of hobby, aircraft, and R/C to your searches.

I did a quick search and found an electric scooter wheel. Not sure of the size.

Also found this 5" wheel.

This wheel claims to have a 3.25" hub.

Their might also be used by electric wheel chairs or hoverboards.
Another idea is to search for "rubber stroller wheels"

That does not appear to be a pneumatic wheel.

That is technically an inflatable mandrel for a sanding drum. I don't know too much about these. It could be an interesting experiment, but I think you would have to provide a tread; otherwise it would wear out too fast.

This wheel claims to have a 3.25" hub.

That is the hub width, the hub diameter is 8.75" and the overall diameter is 10"

That looks good. Here are direct links for the tube (http://www.enertionboards.com/electric-skateboard-parts/5x1-5-spare-all-terrain-tube/) and tire (http://www.enertionboards.com/electric-skateboard-parts/5-inch-all-terrain-tyre-spare/). It is strange that I can't find any information on that site about the hubs, other than some images of them.

I think that is your best bet if you need to carry a significant load. Unfortunately, most seem to be 8".

The issue you might see with airplane wheels is that they are designed for takeoff, landing, and some taxiing. Continuous ground use might cause excessive wear. Also, they don't seem like they would be very good at transmitting torque, but I could be wrong about that.
