It's normal to perform the mechanical alignment and balancing tires when we take the car to periodic review. But do people know the importance of each? It is still common in the market doubt on the best way to achieve these fundamental services to extend the life of a tire and suspension components. "You need to be cautious and understand each procedure performed in the car," warns José Carlos Quadrelli, General Manager of Sales Engineering Bridgestone.
Alignment
Alignment is an important service and should be done when it feels difficult to drive the car straight and when the vehicle starts pulling to one side. The uneven tire wear is another indication that the vehicle is not properly aligned.
The term alignment actually means to seek the "Balance in Motion" vehicle. This procedure is performed by measuring and adjusting the angles that the wheels of the vehicle are relative to the floor and the center line of the vehicle, balancing all the forces acting on the car, such as gravity, centrifugal force, cornering force, etc. providing greater efficiency rolling, uniform wear of the tire improved stability and therefore greater safety for driver and passengers.
The three most important angles are:
Jibe - it consists in an adjustment of the angle of tilt of the wheel relative to the ground. "The main evidence that is necessary to make this adjustment is also uneven wear on a tire's shoulders," says Quadrelli.
Caster - is the angle of the kingpin or steering axis (the imaginary line that passes through the upper and lower pivots of the suspension) from the vertical - provides stability and directional self-centering;
Convergence or Divergence - Is the difference in distances between the fore and rear tire (viewed from above). Your setting promotes an improvement in the standard of the tires, especially under braking.
Balancing
Balancing usually comes with the alignment. There are balances "tires", but the tire and wheel. There are two ways of balancing, static and dynamic. Balancing "static" can be done with the set property. Already the "dynamic" requires that it be in rotation and help fix problems that can not static. These systems measure the forces generated by the rotating assembly. When the dynamic equilibrium is achieved, the static is automatic and does not need to do it separately.
Both forms of balancing avoid the chatter in the car at speeds above 60 km / h, deterioration of the tire, steering disturbances and impaired braking capability.
The recommendation is that the alignment and balancing are done every ten thousand miles, even if the driver does not feel any abnormal behavior in the car. Instead, you should check whenever changing tires / wheels, steering wheel vibration or vehicle, caster is made of tires, a tire or tube was repaired due to puncture or cut, there was strong against shock obstacle on the track causing warpage or hole in the rim, loss of balance balance rim and / or tire excessively spent at isolated points.
The tire is a durable and important safety item. If the problem is not solved in time, one runs the risk of reducing its useful life, resulting in financial losses and risks for the driver and other passengers.
