Tire Fill
Rely® Flat Proofing Polymers keep your customers rolling
Rely® replaces air in tires with a resilient liquid compound that cures to a soft rubber core within 24 hours and makes tires impervious to nails, spikes, rocks, slag – even bullets.
We continually invest in flat-proofing technology and have a number of polymer formulations blended for specific applications, and we offer the expert training and equipment you need to provide this valuable service profitably and safely.

Rely® Tire Fill Products
Rely® T-15 Flat Proofing Polymer is designed for all purpose industrial applications, where a softer ride is preferred. This elastomer is specifically designed to function in tires run continually at ≤35 mph or for a two hour maximum at 55 mph during an 8-hour shift
Rely® T-25 Flat Proofing Polymer is designed for all purpose industrial and heavy duty applications. This elastomer is specifically designed to function in tires run continually at ≤35 mph or for a two hour maximum at 55 mph during an 8-hour shift.
Rely® T-25 OEM Flat Proofing Polymer is designed to work with our recycling equipment, when crumb is introduced to the process. It is based on our Rely® T-25 product with the same characteristics and designed to function in tires running continually at ≤35 mph or for a two hour maximum at 55 mph during an 8-hour shift.
Rely® T-32 Flat Proofing Polymer is designed for maximum duty use, where less tire flex is preferred and for tires bearing extra heavy loads. Stability is improved through decreased deflection. This polyurethane elastomer is formulated for the most demanding applications where extreme heat and load conditions are factors.

Rely® Tire Fill Pumps
With fewer parts to maintain, this computer-controlled operation fills tires with Rely® Flat Proofing Polymer at up to 58 pounds per minute. Its automatic safety features reduce the risks of tire blowout and accidental off-ratio processing.
Intelli-Pump™ is the easy, safe and economical way to provide tire fill services to your customers.
The Powerfil™ P2000F Rely® processing system was designed by Carpenter Co. engineers specifically for tire retailers. Its lightweight and ergonomic design makes it easy to use, and with the pumping ratio of 6:1, no tire fill dispensing is faster.
