Performance Tests


You’re probably working twice as hard as you need to!

uottawa For years Amerityre® has been saying this is the best tire in the world. We were asked to prove it, so we did.

The most popular wheelbarrow tires used today were purchased from a variety of stores and then tested using a Model GSE 250 Load Cell & Indicator with a Peak Hold Indicator to measure the force required to begin rolling and then maintain the forward movement of the wheelbarrow.

The test was repeated three times at each weight to assure the most accurate readings possible. The testing started at 100 pounds and progressed up to 1,000 pounds in 100-pound increments with the readings being recorded for START, (amount of force needed to start the wheelbarrow moving) and MAINTAIN (the amount of force required to keep the wheelbarrow moving forward). You can see the results of the test on the inside of this brochure.

Comparison of Biomechanical Performances of FlatFree™ Amerityre and Traditional Pneumatic Bicycling Tire

uottawa The biomechanical comparison of a closed cell polyurethane and a traditional pneumatic bicycle road tires were investigated.

The study consisted of 4 amateur cyclists and one former professional cyclist who attend the University of Ottawa. The study compared a closed cell polyurethane tire (Flatfree™ Amerityre tires 700 C x 23mm, replicating ~97 psi) and a traditional pneumatic tire (Vredstein® Recorso tires 700 C x 23mm) on bicycle rollers.
