Tire wheel weights are small, metal objects attached to vehicle wheels to balance the tires and keep them rolling smoothly. They counteract any weight imbalances in the tire and wheel assembly. Made of lead, steel, or zinc, wheel weights come in different sizes and shapes.  They are carefully positioned on the wheel rim to counter uneven weight distribution caused by factors like tire wear and manufacturing differences. By balancing the tires and wheels, wheel weights reduce vibrations, enhance tire performance, and improve the overall driving experience.
