Custom Flat Proofing to Make ANY Tire Flat Free!

Custom flat proofing, often called "foam fill", can make any tire, new or old, 100% flat free! Our preferred product, called EcoFlex, features a softer fill that can be used on any size tire. Smaller tires require a softer fill because hard fill will damage your equipment.

EcoFlex SoftFil- 100% Flat Proof- Guaranteed!

EcoFlex is a patented liquid polyurethane flat proofing polymer that is pumped into the tire through it's valve stem. It replaces all of the air and cures into a resilient, synthetic rubber core in 24 hours! It completely eliminates flats! 100%. Your tires will roll right over spikes, scrap metal, rocks, name it!

EcoFlex is ideal for:

  • Landscapers
  • Contractors
  • Golf Courses
  • Municipalities
  • Homeowners
  • Universities
  • Manufacturing Plants

EcoFlex must be installed by an Authorized Ecoflex Installer

Custom flat proofing is done in a heat controlled, specially equipped pump room at our Worcester Massachusetts location. Please call for more information.

Ecofil is currently manufactured in three different grades/formulas to meet particular load, ride and traction needs. At Ken Jones Tires we always strive to give our customers premium products with exceptional value and that is why we use Ecoflex Ecofil flat proofing. Compared to the standard tire foam fills on the market, Ecoflex is much softer and provides an air-like ride. A softer, air-like ride means less axle stress, less bent wheels, less jolts and vibrations, longer tire wear and a broader footprint for increased traction. Other benefits include constant tire pressure for life of tire, extra ballast for improved stability and elimination of blow out hazards. It is the ideal tire flatproofing solution for lawn tractors, skids steers, golf course equipment, farm tractors, backhoes, trenchers, utility vehicles and construction equipment. Major OEM's such as Mustang and Gehl have approved Ecoflex for the use on their machines. Eliminate 100% of flat tires with Ecoflex....Just Fill It and Forget It !

What is the Ecoflex process?

Pumped into the tire through its valves stem, Arnco's liquid flatproofing polymer replaces all of the air and cures to a resilient rubber-like core in 24-48 hours. All foam filling is done at our place of business. The process includes 1) Inspecting your tire and wheel for defects. 2) Prestretching the carcass overnight. 3) Pumping the tire fill into the tire at the correct temperature. 4) Pressurizing the tire to the recommended inflation pressure. 5) Curing at the proper time and temperature to insure optimum filled tire performance.
