Eliminate flat tires forever with an innovative flat proof tire that has been specifically designed to feel like, but out perform, pneumatic "air filled" tires. The Carefree Tire is a lightweight airless tire that has been manufactured from a proprietary blend of Micro-Cellular Polyurethane (HR) FPF developed by top Arnco scientist.
Just imagine, no more wasted time fixing flats or worrying about under inflated tires ever again!
About Us
Since 1971, the scientists at Arnco have been developing a line of technologically advanced polyurethane products and in 1977 developed a high performance flexible polyurethane formulation. By combining this proprietary blend of micro-cellular polyurethane with a novel manufacturing method of centrifugal casting, the light weight, durable Carefree Tire provides an "air cushioned" ride without adding any significant weight, delivering the assurance and durability of a solid tire with the performance and ride of a pneumatic tire.
Carefree Tires innovative process of manufacturing is specifically designed to create a tire that has a durable non-porous outer elastomeric skin with a high-density cellular core consisting of trillions of trapped air cells. The tough-yet-flexible outer skin allows for a firm tread area that provides excellent resistance to abrasion, cutting, punctures, and chemical attack, while the dense micro-cellular core reduces rolling resistance, and allows for greater shock absorption. As a result, not only will a Carefree Tire last four to ten times longer than a similar pneumatic tire, it requires much less effort to roll.
Since 1977, Carefree Tire LLC has become the world's leading manufacturer of micro-cellular polyurethane FLAT-FREE tires by providing millions of tires into the Industrial, Material Handling, Outdoor Power Equipment, and Medical Mobility markets. In fact, no other tire in its class is specified on more original equipment manufactured in America than the Carefree Tire
We at Carefree Tire & Caster are committed to manufacturing high quality products while following strict in-house safety practices for all its employees. We are ISO 9001:2008, ISO 14001:2004 and OHS 18000 registered.Our Strategic Direction:
To be the company that best understands and satisfies the needs of the Original Equipment Manufacturers that are using small wheels, tires, and casters.
Dynamic Load Test
The purpose of the Dynamic Load Test is to simulate the working environment that the tire may be subjected to and to evaluate the tires durability and performance.
-
Test:Complete tire and rim assembly is mounted into a drum test fixture. Each tire will travel at a rotational velocity of 100 PRMs for a total of 24,000 revolutions under weight loads of 150 lbs and 300 lbs.
-
Results: Due to the high-density cellular core of the Carefree Tires unique design, they prove much better in maintaining original characteristics after flexing under load and have shown less sidewall stress after thousands of flex cycles than the leading competitors Flat Free tire.
The primary cause of rolling resistance is hysteresis:
A characteristic of a deformable material such that the energy of deformation is greater than the energy of recovery. The rubber compound in a tire exhibits hysteresis. As the tire rotates under the weight of the vehicle, it experiences repeated cycles of deformation and recovery, and it dissipates the hysteresis energy loss as heat. Hysteresis is the main cause of energy loss associated with rolling resistance and is attributed to the viscoelastic characteristics of the rubber.

Thus materials that flex more and bounce back slowly, such as rubber, exhibit more rolling resistance.
With continuous cycling of the rubber pneumatic tire under load. The tire looses air pressure. Lower pressure results in even more flexing of sidewalls. This energy conversion in the sidewalls increases rolling resistance and can also lead to tire failure.
DEFLECTION (INCH)
Tire Rebound Damping / Shock Absorption:
-
Test: Each tire is dropped from a 48" height to compare rebound and effective wheel bounce damping.
-
Results: Carefree Tires prove to absorb shock and dissipate excess energy better than the leading fully inflated pneumatic brand tire and drastically out perform the competitors version of a Flat Free tire.
Shock originating by the tire traveling over irregularities of the ground are readily transmitted to the equipment which, in turn, can result in a discomfort to the individual operating the equipment. Carefree Tires innovative design and tire composition absorb excess energy and better dissipate vibration
Break Away Roll Force Test
-
Test: Break away force under loads of 250 lbs , 350 lbs , 500 lbs
-
Results:Carefree Tire performed slightly better than the leading fully inflated pneumatic tire brand and drastically out performed the competitors version of a Flat Free tire.
Continuous Roll Force Test
-
Test: Continuous force under loads of 250 lbs , 350 lbs , 500 lbs
-
Results: Carefree Tire performed slightly better than the leading fully inflated pneumatic tire brand and drastically out performed the competitors version of a Flat Free tire.
The Environmental Impact
Rubber tires are among the largest and most problematic sources of waste.
Approximately one rubber tire is discarded per person per year.
The U.S. Environmental Protection Agency reported 290 million scrap rubber tires were generated in 2003. Pneumatic, or air filled, tires that are no longer suitable for use due to wear or irreparable damage (such as punctures) are among the largest and most problematic sources of waste generated today.
In use, and when discarded, rubber-based tires break down through exposure to ozone, abrasion, heat, humidity and other factors. Studies show that zinc, heavy metals, a host of vulcanization and rubber chemicals leach into water from tires. Many organisms are sensitive, and without dilution, contaminated tire water has been shown to kill some organisms.
* At least four chemicals used in rubber are known carcinogens, including 1,3-butadiene, chloroprene, sulfuric acid and benzene, according to the Report on Carcinogens, 9th Edition.
The Environmental Advantages of a Carefree Tire
Carefree Tire products are made of polyurethane foam which has little tendency to break down, leach or burn. Finished polyurethane is devoid of carcinogens. Unlike rubber, polyurethane is ozone and ultraviolet light-resistant. Also unlike rubber tires, polyurethane tires can be disposed of in municipal landfills with no adverse impact. With Carefree Tires lasting up to 10 times longer than pneumatic tires, we could reduce landfill waste dramatically if Carefree Tires were used in place of pneumatic air filled tires.
Rolling resistance affects the environment throughout a tire’s useful life. When a rubber tire has any loss of air pressure, the rolling resistance is increased, more energy is used, tire temperature increases and the tire wares prematurely thus ending the life of the tire.
Carefree Tires are truly “FLAT PROOF”! The Micro-cellular foam structure of a Carefree Tire allows it to ALWAYS perform like a pneumatic tire that is properly filled with air, reducing the rolling resistance and increasing tire life by as much as 10 times.
Increase the life of your tire and the quality of your life by using a Carefree Tire .
