Looking for a Polyurethane Tire Fill Kit? Start Here.
With TyrFil, choosing tire fill involves more than matching a kit to a tire size. The formulation, amount of fill, and installation all need to suit the tire and the work it does. One thing to know up front: TyrFil is professionally installed, not a do-it-yourself kit. An authorized dealer can help you figure out what fits your equipment and arrange the work.
Here’s what to consider before you get started.
What Are You Buying When You Choose Polyurethane Tire Fill?
With TyrFil Flatproofing, liquid polyurethane is pumped into an off-the-road (OTR) pneumatic tire, displacing the air and curing into an elastomer core.
That makes product selection more involved than choosing a package by tire size alone. Your load, operating conditions, and ride requirements also help determine the appropriate material.
Start With the Job Your Equipment Does
Before requesting a quote, gather your tire size, equipment make and model, typical loads, and a description of the worksite.
Then think about the problems that are getting in your way.
- Are punctures a recurring issue?
- How often does a flat interrupt work?
- What does an interruption cost in repair time, idle labor, and rescheduling?
Share those details with your dealer. A clear picture of the job helps make the recommendation more relevant, and gives you a better basis for deciding whether flatproofing is worth the investment.
Choose a Formulation That Fits
TyrFil comes in several formulations, each suited to different operating needs. Flex allows more tire deflection for an air-like ride. Pro is designed for general-purpose use. HeviDuty is made for heavy loads, while Ultra is built for severe conditions and enhanced heat dissipation.
The formulations also differ in durometer, or material hardness. A lower durometer means a softer fill; a higher one means a harder fill.
You don’t need to know all the technical details before you talk with a dealer. Just be ready to describe what your equipment carries and the conditions it works in.
How Much Tire Fill Will You Need?
The amount of tire fill you need depends on the tire and wheel setup. Carlisle’s Tire Weight Calculator can give you a starting estimate. Have your tire’s outside diameter, section width, and rim diameter handy, and select the product you’re considering.
Use the result as a ballpark, not a final order quantity or quote. Wheel designs vary, and drop-center wheels need more material than standard wheels. Your dealer can confirm the amount you’ll need before you place an order.
What About Installation and Cure Time?
TyrFil is installed with dedicated tire fill processing equipment, so it’s helpful to plan for professional installation from the start.
Ask your dealer what preparation is needed, who will do the work, and when your equipment can return to service. Carlisle lists a typical cure time of 24–48 hours in its flatproofing FAQs. Your actual schedule may vary, so confirm the timing with your dealer.
Planning ahead can help you schedule the downtime around your work instead of waiting for a flat to do it for you.
Ask for a Quote That Covers the Whole Job
When you compare options, be sure to ask for an installed quote that spells out what’s included: the recommended formulation, fill quantity, tire preparation, installation, and expected turnaround.
Then compare the full cost with what flat-related interruptions have already cost your operation. Factor in repairs, how long the machine sits idle, and any work that gets delayed.
The question is whether the investment makes sense for your equipment and your operation over time.
