Tire of highspeed rotating motion in a circular manner and then from the center to generate centrifugal force.Wheel hub, brake drum is not allowed (plate) when machining axis positioning, great error in the machining, the machining surface of casting, heat treatment deformation, great error in the use of deformation or uneven wear of wheel bolt quality range, wheel hub quality distribution or radial circular runout, face round beating too big Tire quality distribution, size or shape error is too big, in the use of or renovation tire uneven wear, use or pad, tire repair And didymous inflatable mouth not 180 degrees apart, singletons inflatable mouth with no balance mark apart 180 installation of wheel hub, brake drum, tire bolts, rim, inner tube, liner after removal to assemble into belt, tires and other tires, accumulated the imbalance of quality or form a deviation is too big, destroyed the balance of the original(then called dynamic imbalance) then with wheel balancing machine, dynamic balance test wheel, simply is to detect a certain point than it symmetric point light how much or how much weight, with the balance piece of clip to the tire to adjust balance, balance weight also calls the counterweight, usually with card clip and paste two types] balance is stuck piece, can be fixed on the tyres.
To the wheel balance weight, use: balance of on the road wheels Do the balance is to make the steering wheel speed not jitter Wheel rolling on the road, meet the road is rough and extrusion of body, will make a point of centrifugal force does not agree with his symmetric point, when the wheel to tell, can make the tyres for normal wear and tear, serious still can steering system components to speed up the wear and tear, strictly speaking, the range of 3000 to 3000 kilometers, the wheel should be to adjust the dynamic balance, is to knock some balance faster.
