Feature 1P Style wheel balance weights used on all steel wheels up to 17in passenger cars & light trucks. 2Will prevent the tires from vibrating under high-speed operation, and ensure the normal running of the vehicle. 325g1g /0.880.04oz per weight, and 40pcs weights each pack, small weight error with large quantity to meet yor needs. 4Compensated for the wheel with a balance weight, and the dynamic balance of the wheel is corrected by locally increasing the weight. 5With this balance weight, there will be no problems such as steering wheel shake and vehicle body shake during high-speed driving.Condition: 100% Brand NewItem Type: Tire Wheel Balancing WeightsMaterial: Aluminium AlloyColor: As Pictures ShownType: P StyleWeight of Single One: Approx. 25g1g /0.880.04ozQuantity: 40pcs/PackWeight of Each Pack: Approx. 1000g10g /35.270.35ozApplication: Use on all steel Wheels up to 17in for Passenger Cars & Light TruckIntroduction:The wheel of a car is a whole composed of tires and wheels.Due to manufacturing reasons, the mass distribution of each part of this whole cannot be very uniform.When a car wheel rotates at a high speed, it will form a dynamic imbalance state, resulting in the phenomenon of vehicle wheel shaking and steering wheel vibration during driving. Dynamic balance refers to the asymmetric weight distribution produced by the force of the tire when it rotates, usually at a higher speed.In the tire factory, a balancing machine installed on the tires and wheels tests the wheels. The assembly is accelerated to 300 RPM or higher, and the force imbalance is measured with the tire rotation sensor.For the hook-type balance weight, the unreasonable fit clearance is also the reason for its loss during driving. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Pack of Tire Wheel Balancing Weights (40pcs, 25g/pc)NoteProfessional installation is strongly recommended.
