Aero-flex™ Foam Fill

Comfort Track & HD Foam Fills

Flat-proof Your Wheelchair

Non-pneumatic tires are low on maintenance and high on reliability.

If your tire never goes flat, or you never have to air fill your tire – the stress associated with unreliability of the wheel is mitigated.

Foam fills inserts can be added to pneumatic tires to make them non-pneumatic.

Dual Density Foam Fills

Aero-flex II™ tires consist of the right proportions of Aero-Flex I and Aero-Flex II compounds. This combination allows the user to take advantage of the beneficial features of both these materials in one single product.

The harder, Aero-Flex I compound is placed on the inside of the circumference, near the rim. The softer material Aero-Flex II is placed on the outside right under the tire tread. The tougher material does not budge and provides a safe ride, while the softer material, provides a softer smoother ride.

The tougher material disperses the vibrations experienced on impact while the softer material absorbs it. By using a combination of both the materials, the tire exhibits positive properties of both materials. Hence, it is more effective as compared to either of the materials being used on their own.

Production Technology: SPIN-Cast Molding

The process of spin-cast molding is used to insert foam fill into tires. This process helps create a dense, firm tread area while keeping the sidewall area flexible. The distribution of the foam fill is even and accurate ensuring excellent shock absorption. This helps provide the user with a smooth ride, every time.
