No Flats.
No Downtime.
No Compromise.
TyrFil Flatproofing is a polyurethane material that replaces all air in Off-the-Road (OTR) pneumatic tires, curing into a flexible, shock-absorbing elastomer core. For over 50 years, TyrFil has helped companies worldwide eliminate flats, improve operator safety, and reduce equipment wear—offering a smoother ride and better value than solid aperture tires.
The Hidden Costs of Solid Aperture Tires.
The greatest advantage of TyrFil over other No Flat options, including solid aperture tires, is the smoother ride as a result of a substantially lower G-force transmission. Higher G-force transmission can cause operator injury and premature wear and tear on equipment components.

Flatproofing Solutions for All Types of OTR Conditions
Durometer measures how hard or soft a material is. Higher durometer = harder and more durable. Lower durometer = softer and more flexible. Pick the best TyrFil flatproofing formula based on your equipment’s load and performance needs.
Low Durometer
TyrFil Flex (Durometer 10)
Provides maximum deflection and an air-like ride—ideal for skid steer operators seeking top-tier shock absorption and comfort.
High Durometer
TyrFil HeviDuty (Durometer 55)
Built for the heaviest loads, HeviDuty combines added durability with minimal tire deflection—perfect for high load, slow moving applications.
Medium Durometer
TyrFil Pro (Durometer 30)
A versatile, general-purpose solution suitable for about 90% of tire fill applications, delivering balanced performance and reliability.
TyrFil Ultra (Durometer 30)
Engineered for severe conditions such as underground mining, this formula offers superior heat dissipation in high-load environments.
How Does TyrFil Flatproofing Work?
TyrFil is pumped into pneumatic OTR tires, fully replacing the air. It then cures into a resilient elastomer core that retains the tire’s natural flex while eliminating punctures or blowouts.
The result? Zero flats and a more comfortable ride—from construction and mining to agriculture and beyond.
