A tire balancer is a machine used to ensure that a vehicle's tires are evenly balanced. When tires are installed on a vehicle, they can sometimes have slight weight differences that cause vibrations while driving. A tire balancer helps identify these imbalances by spinning the tire and measuring any discrepancies, allowing for adjustments to be made. Proper balancing of tires is essential for a smooth ride and can extend the life of the tires. It also contributes to better handling and fuel efficiency. Regular use of a tire balancer is recommended during tire installation or rotation to maintain optimal performance of the vehicle.
