Finding the right truck tire balance with IMI For 42 years, Pennsylvania-based IMI has worked on wheel balancing products for truck tires, most prominently its Equal balancer. Now, the company has released an enhanced version of that product, known as Equal Flexx. Fleet Equipment visited IMI headquarters in Chambersburg, Pa., to take a look at the Equal Flexx wheel balancer, a powder which goes inside the tires and removes 10 to 15% more vibration from the wheel-end, increasing tire mileage by up to 45%. It also decreases vibrations in the cab, leading to a more comfortable ride. FE rode along in one truck without Equal Flexx in its tires, and one with it, to see the differences for ourselves. Watch the video above to see how Equal Flexx can help drivers and reduce costs of tires and fuel.
