Polyurethane Foam Fill Manufacturing Built for Maximum Uptime
Carlisle TyrFil isn’t just a manufacturer. We are the industry authority in polyurethane-based tire fill technology, engineered for performance and durability.
With over 500 years of combined expertise, we’ve built our reputation on one thing: delivering flatproofing solutions that perform in the toughest conditions, where downtime isn’t an option.
We design and manufacture advanced polyurethane tire fill formulations engineered to:
- Eliminate flats and unplanned downtime
- Extend tire and equipment life
- Improve operator safety in demanding environments
- Support long-term performance and sustainability
Through continuous investment in polyurethane tire fill manufacturing R&D, we don’t follow industry standards. We set them.
No other provider matches the combination of:
- Proven innovation
- Depth of product range
- Global technical expertise
- Dedicated, hands-on support
Because when your equipment is critical to operations, reliability isn’t optional. It’s everything.
Converting Pneumatic Tires into Flatproof, Performance-Driven Tires
By converting a pneumatic tire into a flatproof, performance-driven tire,TyrFil delivers measurable operational advantages:
- Eliminates downtime caused by flats
- Reduces maintenance and tire replacement costs
- Extends tire and equipment lifecycle
- Maintains consistent internal tire pressure
Even in hazardous environments, our polyurethane foam fill ensures filled tires continue to perform despite cuts or punctures for uninterrupted operation.
Polyurethane Foam Fill for Demanding Environments
Shock Absorption
Reduces vibration and G-force transmission compared to solid aperture tires, minimizing operator fatigue and equipment stress
Consistent Load Support
Maintains uniform pressure and contact patch under varying loads and terrain conditions
Flatproof Integrity
Eliminates punctures and blowouts by removing air from the tire entirely.
Improved Stability
Adds weight and lowers center of gravity, enhancing machine stability and traction in demanding environments
The Polyurethane Foam Fill Installation Process
TyrFil flatproofing is a two-component polyurethane system that replaces air in pneumatic Off-the-Road (OTR) tires with a resilient, load-bearing elastomer core.
Here’s how it works:
01 | Pump with Precision
TyrFil is delivered as a two-component polyurethane system (ISO + catalyst) in a controlled 1:1 ratio and pumped directly into the tire cavity through the valve stem—ensuring consistent material distribution and performance.
02 | Fill & Form the Core
As the material fills the tire, it fully displaces the air creating a flexible, elastomer core that:
- Maintains tire footprint and load distribution
- Resists punctures, cuts, and blowouts
- Preserves structural casing integrity
03 | Cure into a Flatproofed Tire
Within 24–48 hours, the material cures in place—creating a flatproof, flexible elastomer core built for demanding applications.

Answers You Can Count On
1. Does the polyurethane foam fill reduce tire load capacity?
No. TyrFil polyurethane formulations are engineered to maintain or enhance load-bearing performance when properly matched to the application.
By eliminating air pressure variability, filled tires provide consistent load support and improved stability, especially under heavy or uneven loads.
2. How do polyurethane foam-filled tires compare to solid aperture tires?
Polyurethane-filled pneumatic tires deliver a hybrid performance advantage:
- Maintain the flex and footprint of pneumatic tires
- Provide flatproof reliability similar to solid tires
- Offer superior shock absorption and reduced vibration compared to solid aperture designs
This results in improved operator comfort, reduced equipment stress, and more consistent performance in demanding environments.
3. What temperature range can polyurethane foam-filled tires handle?
TyrFil-filled tires are engineered for extreme operating conditions, with performance ranging from:
- -60°C (-76°F) to
- 160°C (320°F)
This wide thermal range allows consistent performance across cold-weather, high-heat, and continuous-duty applications without degradation in material integrity.
4. What is durometer and why does it matter?
Durometer measures the hardness of the polyurethane material, which directly impacts performance.
- Lower durometer → more flex and shock absorption
- Higher durometer → greater load capacity and stability
Polyurethane foam fill systems allow custom tuning by application, unlike solid tires, giving operators control over ride quality, heat resistance, and performance.
