Carpenter Co. – A Global Leader in Polyurethane Tire Fill Technology

Founded in 1948, Carpenter Co. is one of the world’s largest manufacturers of polyurethane foam and advanced polymer technologies. Over the decades, the company has expanded its expertise into numerous industries, including bedding, automotive, industrial applications, packaging, and polyurethane chemical systems. One of its most respected industrial solutions is its Rely® Tire Fill System, which has become a trusted choice for companies seeking maximum tire reliability and productivity.

Advanced Tire Fill Technology

Carpenter’s Rely® Flat Proofing Polymer replaces the air inside a pneumatic tire with a specially formulated liquid polyurethane. Once injected, the material cures into a resilient elastomeric core, typically within 24 hours, creating a puncture-proof tire while maintaining many of the ride characteristics of an air-filled tire. This technology eliminates flats, reduces downtime, and significantly improves equipment reliability in demanding environments.

Designed for Heavy-Duty Applications

Rely® Tire Fill is widely used across industries where tire failure can result in costly downtime. Typical applications include:

• Forklifts
• Underground mining equipment
• Wheel loaders
• Excavators
• Skid steer loaders
• Aerial work platforms
• Mobile cranes
• Quarry equipment
• Waste handling equipment
• Port and terminal vehicles
• Construction machinery

These industries rely on Rely® because puncture resistance directly translates into increased productivity and lower operating costs.

Multiple Formulations for Different Needs

Carpenter offers several polyurethane formulations to match different operating conditions:

• Rely® T-15 – Provides a softer ride for general industrial applications.
• Rely® T-25 – Designed for heavy-duty industrial equipment and everyday demanding use.
• Rely® T-25 OEM – Optimized for recycling processes while maintaining the same performance characteristics as T-25.
• Rely® T-32 – Engineered for maximum load capacity, reduced tire deflection, and extreme operating environments with high heat and heavy loads.

Professional Filling Equipment

In addition to polyurethane materials, Carpenter manufactures professional tire filling equipment, including the Intelli-Pump™ and Powerfil™ P2000F systems. These machines are designed to deliver accurate mixing ratios, improved safety, and efficient tire filling, allowing service providers to perform high-quality foam filling consistently.

Key Benefits of Rely® Tire Fill
