You can certainly do it in lawn tractors, UTVs, wheelbarrows, etc. I just did four of them on a yard cart a few weeks ago. How much would it cost to repair a tubeless tire with a sidewall puncture by installing a tube into it?

The Air-Free Flat-Free tire may look like a pneumatic, but it's actuallymade of solid polyurethane and features a saw-toothed tread. It has the same bounce and load handling as an air-filled tire, but without the required maintenance of re-filling air into the tire every now and again - making it flat-free.

Something that is “pneumatic” means it is operated by gas or air under pressure, which would give you a hint of what a pneumatic tire is. If you guessed an air-filled tire, you'd be right. Now the other tire is called a “flat-free” which basically means the opposite of pneumatic anddoes not need air to be functional.
