Correct wheel alignment improves road holding and maximises the life of tyres. Aligning the front two wheels resolves alignment issues for most vehicles. Not all cars can have the rear wheels adjusted so any additional requirement for all four wheels to be adjusted needs to be discussed with the auto service centre once the initial check is done.
What is wheel alignment?
Wheel alignment (or 'tracking') refers to the angle and direction at which the tyres are set.
Hitting kerbs or driving at speed through a pothole can result in wheel misalignment. Poorly aligned tyres can affect road holding, increase fuel consumption and decrease the life of your tyres.
How do I know if my wheels need to be aligned?
Watch out for these classic signs of wheel misalignment:
Uneven tyre wear
Steering wheel pull (the steering wheel pulling to the left or right when driving on an even surface)
How can I get my wheels aligned?
If you spot the signs of misaligned wheels, come to auto service center and the technicians there will correct the problem.
