Auburn University
An independent study by Auburn University measured truck steering column and seat vibration with and without Centramatic balancers on steer and drive axles. Results show balancers significantly reduce steering wheel vibration, with the lowest vibration occurring when balancers are used on both axle sets.

An independent study by Engineering System International (ESI) using physics-based simulation found that Centramatic wheel balancers provide a 2.11% fuel savings for Class 8 trucks. This reduction in fuel consumption is achieved by decreasing rolling resistance, leading to significant annual cost savings and lower emissions.

Meadows Analysis conducted a Finite Element Analysis (FEA) to quantify the energy cost of an unbalanced truck wheel. A 6 oz imbalance on a 46-inch tire at 66 mph was found to create 353 pounds of force and consume an extra 25.8 horsepower, demonstrating significant wasted energy.

A 1998 field evaluation by Speed Measurement Laboratories, Inc. tested Centramatic balancers on a Kenworth car hauler. The study found the balancers reduced wheel temperatures by an average of 10% on front steer wheels and 8% on rear drive wheels, validating the company's 'ThermoFlow' heat dissipation claims.

A 2011 study by the Universidade de Brasília evaluated Centramatic self-balancing devices on two interstate buses over 6 months. The tests, conducted in partnership with Real Expresso Ltda., showed significant reductions in tire wear and axle vibration, along with a small improvement in fuel economy.
