Mounting the tire requires putting the actual tires on the vehicle’s wheels, inflating the tire properly and then mounting the tire onto the vehicle’s axles. Before mounting the tires, the mechanic usually balances the tires. Balancing requires specialized equipment that analyzes the wheels and tires and finds any heavy spots that require correction. If there is an imbalance in the wheels, the mechanic applies weights to the tires’ rims in certain locations to distribute the weight more evenly.
To balance the tires, the mechanic places the tire and wheel assemblies on a balancing machine and runs diagnostic tests. The machine lets the mechanic know which wheel assembly and tire requires additional weight. The mechanic may use a machine that simulates road conditions when balancing the tires. The machine presses a large roller against each spinning tire and measures any deviation of roundness to aid in balancing the tire.
Balanced wheels are important to the performance of a vehicle. Imbalances may cause the tires, shocks, suspension components and wheel bearings to wear out prematurely. Vibrations in a vehicle’s ride that often worsen with an increase in speed usually result from wheel imbalance.Learn more about Tires, Rims & Wheels
