Tech Facts?
The Centramatic solution is simple! Weights in Centramatic's aluminum balancing ring move opposite of out of balance points with wheel rotation by centrifugal force, at any speed. The wheel is dynamically and statically balanced at all times. Old fashioned lead weights are attached and can't move.
Large commercial fleets consistently increases in tire tread life up to 50% and elimination of tire hopping from out of balance wheels. When the vehicle is retired, Centramatic's Balancers can transfer to the new vehicle. No obsolescence here! Satisfaction is assured with a 5 year, limited, nationwide warranty and a 30 day, no questions asked money back guarantee.
Centramatic has had the privilege of having their "On-Board" Balancers tested and evaluated by two of the most respected research organizations in the Country: Auburn University's National center for Asphalt Technology (NCAT) and Speed Measurement Laboratories, In.c (SML). At NCAT's facilities the effects on tire mileage and cab vibration were evaluated. Since operating temperature is critical to the endurance life of a tire, SML assessed the validity of Centramatic's ability to decrease this devilitating condition.

PRODUCT
The Centramatic Continuous Wheel Balancer consists of 20-gauge steel galvanized mounting plate with an aluminum balancing tube attached. Shot sized balancing weights are inserted into the balancing tube lubricated by a synthetic moly oil. The balancer mounts behind the wheel and centrifugal force redistributes the balancing weights opposite of out of balance points as the wheel rotates. The Company claims the dissimilar metallic composition of the balancer, i.e. steel mounting plate and aluminum balancing ring, dissipates wheel/tire heating while in operation. This feature is called "ThermoFlow" by the Company. Basic rules of thermal physics apply as different metals have different coefficients of contraction/expansion with convection heat transfer migrating to the metallic content with the highest coefficient of expansion/contraction, i.e. rapid transfer from the wheel/hub/tire assembly to the steel mounting plate to the aluminum tube. The Company has been manufacturing the balancers for sixteen years concentrating on the heavy duty trucking market and RV applications with over 400,000 sets on the road, according to the Company. A set of front balancers for 22.5" wheels and a set of rear balancers for 22.5" wheels were provided to SML for field evaluation.
