Reviews of TyrFil Flatproof Polyurethane Tire Fill by Truckers

Imagine if your truck’s tires never got flat. They can’t if they’re filled with TyrFil (R), a “flatproof” polyurethane tire fill, instead of air. What if you never had to worry about refilling or replacing flat truck tires ever again?

There are seven different products on the market depending on the firmness of the ride desired and whether or not your desire is to be “green” (or eco-friendly).

Disclaimer: We have no connection with this product line, but will relate on this page what it is all about. We’re asking for reviews from professional truck drivers who have used any of the products that go by the name TyrFil (R).

What is TyrFil?

According to their website,

TyrFil is the solution that eliminates flat tires and ALL of its related problems.

Commonly referred to as foam fill, our patented formulations eliminate flat tires, but with the performance and softer-ride of pneumatic tires. TyrFil is a two component liquid urethane that is pumped into the tire through the valve stem, replacing all of the air. The polyurethane liquid then cures into a solid elastomer. Once cured, it protects the tire from punctures and significantly reduces costs of tire repair and replacement. The result is a flat-proofed solid tire, but with a softer ride than a solid rubber tire. No matter how harsh the conditions, TyrFil will perform.

Used in the Trucking Industry?

On their list of Flatproofing Applications, trucking is not specifically listed.

Can it be Used in Truck Tires?

Until Mike was at the location where he got a pneumatic tire replaced on the truck that he drove for one of his local truck driving jobs, he had never heard of this concept before.

He picked up a couple of flyers relating to tire fill polymers.

One of them indicates that the product eliminates the need for tire pressure checks.

Vicki attempted to find information about using such products on the FMCSA’s website.

Using the search term “polyurethane”, she found the following:

Question 4: May tires be filled with materials other than air (e.g., silicone, polyurethane)?

Guidance: §393.75 does not prohibit the use of tires filled with material other than air. However, §393.3 may prohibit the use of such tires under certain circumstances. Some substances used in place of air in tires may not maintain a constant physical state at different temperatures. While these substances are solid at lower temperatures, the increase in temperature from highway use may result in the substance changing from a solid to a liquid. The use of a substance which could undergo such a change in its physical characteristics is not safe, and is not in compliance with §393.3.

Given this, Vicki looked for the melting point of the product on the product’s website but did not find any results.

There is a list of melting points for “chain extenders and cross linkers” used in some polyurethane products, but not for polyurethanes themselves.
