Whether you’re curious about product performance, technical details, or support services, our FAQ page is here to help you make informed decisions and keep your equipment rolling.
What exactly is TyrFil™ Flatproofing?
TyrFil™ Flatproofing is a polyurethane tire fill that replaces the air in Off-the-Road (OTR) tires. It cures into a flexible, shock-absorbing elastomer core that prevents flats and delivers a smoother, more reliable ride.
How does the TyrFil process work?
TyrFil is pumped into a pneumatic tire, completely displacing the air. The product then cures to form a resilient elastomer core that maintains tire pressure, absorbs impacts, and eliminates the risk of punctures.
What benefits can I expect from using TyrFil?
TyrFil eliminates flats, reduces downtime, extends tire life, and lowers maintenance costs. It also minimizes vibrations, which enhances operator comfort and safety.
How long has Carlisle TyrFil been around?
For over 50 years, Carlisle TyrFil has led the industry with innovative tire flatproofing solutions, processing over one billion pounds of product worldwide.
What industries use TyrFil?
Our solutions are used across construction, mining, agriculture, industrial operations, rental fleets, OEM applications, and even military settings—anywhere equipment durability and reliability are paramount.
What different TyrFil formulas does Carlisle offer?
We offer several formulations tailored to various conditions:
TyrFil™ Flex (Low Durometer) for maximum deflection and an air-like ride,
TyrFil™ Pro (Medium Durometer) for general-purpose applications,
TyrFil™ Ultra (Medium Durometer with enhanced heat dissipation) for severe conditions, and
TyrFil™ HeviDuty (High Durometer) for extreme heavy-load scenarios.
How do I choose the right TyrFil formula for my needs?
Select a formula based on your equipment’s load, operating conditions, and performance requirements. Our technical guides and online tools can help you determine the best match.
Can tires filled with TyrFil be retreaded?
Yes, tires filled with TyrFil™ flatproofing can be retreaded up to four times without compromising performance, extending tire life and reducing replacement costs.
How does TyrFil improve operator safety?
By reducing G-force and vibration transmission, TyrFil minimizes Whole Body Vibration (WBV), lowering the risk of back pain, fatigue, and other stress-related injuries for operators. Learn more about operator safety here.
Is TyrFil flatproofing a sustainable choice?
Our flatproofing system extends tire life, reduces waste, and is part of a closed-loop recycling program that cuts petrochemical use—saving money and reducing environmental impact.
When should ReSeal be used instead of TyrFil flatproofing?
ReSeal™ is a tire sealant used when equipment is exposed to occasionally harsh conditions. It seals punctures up to ½ inch. It is also a great option to use to extend tire life in hard to find tire sizes.
What kind of support does Carlisle TyrFil provide?
We offer comprehensive support including technical assistance, training programs (like TyrFil University), detailed product documentation, and access to a global network of authorized dealers.
How can I find an authorized TyrFil dealer near me?
Use our Find a Dealer tool to connect with a local authorized dealer who can provide personalized recommendations and support for your specific needs.
Where can I learn more about tire flatproofing and your products?
Visit our Resource Library for collateral, technical guides, videos, and additional information, or contact our support team for personalized assistance.
Does the extra weight from TyrFil affect performance?
No – the added weight lowers the center of gravity and reduces wheel slippage, boosting overall safety.
Can I adjust tire pressure after filling with TyrFil?
No, once a tire is filled with TyrFil, further pressure adjustments are unnecessary.
What speeds are safe with TyrFil?
Where permitted, vehicles can run at 55 mph (90 kph) for up to 4 hours, or continuously at 38 mph (60 kph).
Will TyrFil reduce the tire’s lifespan?
Not at all – the durable, elastomer core actually extends tire life and minimizes wear.
Can a TyrFil-filled tire leak if damaged?
No, once cured, TyrFil forms a resilient elastomer core that prevents leaks.
Does using TyrFil lower the tire’s load capacity?
No, the load capacity remains as specified by the tire manufacturer.
How do TyrFil-filled pneumatic tires compare to solid aperture tires?
TyrFil-filled tires deliver a smoother, more comfortable ride, improved traction, lower heat buildup, and better fuel efficiency than solid aperture tires.
Are there temperature limits for TyrFil-filled tires?
Pneumatic tires filled with TyrFil can safely operate in extreme conditions, from -36°F (-60°C) up to 320°F (160°C).
How soon can I use a TyrFil-filled tire?
TyrFil fully cures within 24 to 48 hours, making your tire ready for trouble-free operation.
