Are you noticing a vibration while driving? Talk to an automotive mechanic to weed out causing-shaking possibilities i.e. wheel alignment, engine or transmission problems, driveshaft and axle failures, suspension wear or too much road force weight on one or more tires can be the culprit of vehicle vibration. Road force balancers, in addition to traditional balancing tires, is to measure both the tire and wheel by pressing a big roller against the spinning tire’s tread. The roller applies 1,200-1,400pound (0.64 ton) pressure to simulate the vehicle’s weight on the tire as it rolls down the road. 

Along with several sensors, it is a computer in the machine that determines variations of radial runout, tire stiffness, and anything in the tire’s assemblage (like inconsistencies in the belt package) that’s preventing the tires from rolling smoothly when weighted by the car. 

 

By measuring both tires and wheel, the road force balancer tells the mechanic where to move the tire around on the
