Karman Flat-Free Wheel

Flat free wheel is a wheel which is solid without air inside, it different from the rubber pneumatic wheels. When working outdoors, using regular inflatable tires can lead to unexpected incidents such as air leaks or tire bursts, which can significantly impact our work progress and waste time and cost. In such situations, flat-free wheels provide an excellent solution. Flat-free wheels offer similar elasticity and load handling characteristics as inflatable tires, but with the advantage of being solid and never leaking air. Flat-free wheels make our usage more convenient and straightforward, requiring no maintenance in our daily lives.

PU Flat-Free Wheel

These flat-free wheels are made of solid polyurethane foam, offering the same driving and handling characteristics as pneumatic tires, but without the worry of punctures and tire bursts. This innovative material is commonly used for equipment such as wheelbarrow, hand trolley, and lawnmowers. PU flat-free wheels require no regular maintenance and provide enhanced durability for long-lasting performance. They are highly beneficial for our outdoor equipment usage.

Solid rubber wheels have the ability to carry heavy goods. Most forklift tires are flat-free solid rubber tires, known for their durability and high load capacity.

How to Buy Flat-Free Wheels Correctly

  1. Firstly, determine the intended use of flat-free wheels. Flat-free wheels made of PU material have advantages such as lightweight and vibrant colors. They are particularly suitable for low load capacity and low-speed applications, making them ideal for lawn and garden work. Not only do they protect the grass, but colored PU flat-free wheels also enhance the aesthetic appeal of the surroundings. For high load capacity and demanding road conditions, rubber flat-free wheels are the preferred choice.
  2. Select the appropriate size based on different equipment. Single-wheel hand carts typically use 13-inch, 15-inch, and 16-inch flat-free wheels. Warehouse carts commonly use 10-inch, 9-inch, and 8-inch flat-free wheels. Small tool carts usually use 4-inch, 6-inch, and 8-inch flat-free casters.
  3. Choose the suitable tread pattern based on the usage environment. For lawnmowers, options include turf tread or smooth tread flat-free wheels, providing sufficient traction while maximizing lawn protection. For industrial applications, square or straight-line tread patterns can offer adequate traction.

Of course, purchasing the right flat-free wheels also requires a deeper understanding of the wheel-related details. When you have any doubts or questions, please feel free to start our conversation.

What are the Advantages of Flat-Free Wheels Over Other Types of Wheels?

Compared to other types of wheels, flat-free wheels have the advantages of:

No Maintenance

Air-filled wheels need to be inflated with air prior to use. Their air pressure needs to be checked before use.

On the other hand, wheels that are flat-free do not require air. As a result, they can be used conveniently and readily.


Other rubber wheels will crack or rot when exposed to heat, chemicals, or UV rays. On the other hand, flat-free solid PU wheels will not crack or rot as they are resistant to those elements.

Lasts Longer

Flat-free wheels have longer lifespans since they are stronger than air-filled rubber wheels. Their service life usually ranges from 3-5 years. They can last more than that depending on how they are used.

As an example, air-filled wheels can’t be used when they roll over sharp items. However, wheels that are flat-free can still function well even in sharp and rough areas. Therefore, they are more long-lasting.
