UPS Approves IMI's Equal Flexx Product

UPS has approved IMI's Equal Flexx product as part of its 2026 tire solutions program following a two-year field evaluation.

"The evaluation included more than 10,000 tire and wheel assemblies – including 19.5inch package car tires and 22.5-inch Class 8 tractor tires – tested under real-world operating conditions," say IMI officials. "Results demonstrated consistent performance and reliability across applications.

"Throughout the evaluation, performance data confirmed that Flexx functioned as designed, delivering superior results compared to mechanical spin balancing with wheel weights. In a few isolated cases where vibration was identified, further inspection revealed pre-existing mechanical conditions such as bent wheels, out-of-round tires or loose components, reinforcing Flexx's ability to surface underlying issues that might otherwise go undetected."

"This two-year evaluation demonstrates the value of rigorous testing and collaboration," says Robert Fogal, IMI president and CEO. "UPS's approval of Flexx not only validates the product's performance but also highlights its ability to support a smoother ride and identify mechanical issues that impact long-term fleet performance."
