Everything You Need to Know About Laser Wheel Alignment

Laser wheel alignment is one of the most reliable and cost-effective ways to check a vehicle's wheel geometry. It is fast, accurate and simple to operate, which is why it remains a popular choice for garages across the UK. In this guide, Supertracker explains everything you need to know: what laser wheel alignment is, what it measures, how the process works, what it costs, and how to tell when a vehicle needs it.

What is Laser Wheel Alignment?

Laser wheel alignment is a method of checking a vehicle's wheel angles using beams of light projected between gauges mounted on each wheel. It lets a technician measure toe, camber and caster quickly and accurately, then adjust the wheels back to the manufacturer's specification.

Although it sounds complicated, laser wheel alignment is a simple process. The laser wheel alignment method ensures that the wheels of the vehicle are set to the optimum position, using beams of light to check that your car’s wheels are aligned correctly.

The alignment process helps to protect your vehicle from uneven tyre wear by ensuring that the tyres have as much surface area making contact with the road as possible, as well as improving handling and safety.

 

What Does Laser Wheel Alignment Check?

Laser wheel alignment uses beams of light to check if the wheels of the vehicle are set up as they should be. This means the wheels are configured to point at specific angles to ensure the car rolls along smoothly, not just pointing forwards. The Supertracker laser wheel aligner range measures these angles simply and accurately. The following angles are checked:

  • Toe-in/Toe-out - The direction the two front wheels point relative to each other
  • Set back - One wheel on the same axle is set further back than the other
  • Camber - The angle of the wheels in relation to the road
  • Caster - The degree the vehicle steering axis is tilted forward or backward from vertical, when viewed from the side
  • Thrust angle - The direction the rear wheels point relative to the vehicle's centreline

Take a look at our breakdown of wheel alignment angles to find out more about what these angles mean. 

 

Can Laser Alignment Do Four-Wheel Alignment?

Yes. Most modern vehicles need a full four-wheel alignment rather than front-wheel tracking alone, and laser wheel alignment systems are built to measure all four wheels. A four-wheel laser alignment checks the front and rear geometry together, so the technician can confirm the rear wheels are square to the vehicle's centreline before adjusting the front toe. This matters because a rear misalignment left unchecked will pull the steering off-centre even after the front is set correctly. For workshops comparing systems, our full range of wheel alignment tools and equipment covers both laser and computerised options.

 

How is Vehicle Wheel Alignment Tested?

The laser wheel alignment systems we manufacture are quick and easy to use, accurate and durable, and built in the UK to last. You can explore our laser wheel alignment machines or contact our team to discuss your workshop's needs.

The vehicle is put on a ramp, allowing the wheels to rotate. Gauges are attached to each of the wheels and a light beam is shone from one wheel to another. From this, the technician can calculate the alignment from where the laser falls on the scales on each wheel. Depending on where the beams of light fall on a scale, the technician can see whether the wheels are in or out of alignment. With the use of a Digital Camber Castor Gauge, Camber and Castor can also be measured - if necessary, corrections will be made to restore the alignment.

 

How Do I Know if My Car Needs a Wheel Alignment?

Wheel alignment problems can be caused by day-to-day driving on poor quality roads, driving over potholes, hitting the curb or from excessive wear to steering components. Getting your wheel alignment checked regularly will ultimately help to prolong the life of your tyres and improve your vehicle's safety as well as increasing fuel efficiency.

Key indications of wheel alignment issues include:

  • The steering wheel is off-centre when driving straight
  • Uneven tyre wear
  • Steering wheel vibration

 

How Much Does Laser Wheel Alignment Cost?

The cost of a laser wheel alignment depends on the vehicle, the number of angles being adjusted and whether the work is carried out in-house or outsourced. For a workshop, the bigger commercial question is the cost of not having a laser aligner on site: every alignment sent elsewhere is lost revenue and a customer leaving the premises. A laser system is the most cost-effective entry point into offering alignment in-house, with a fast return on investment from work that would otherwise be turned away.
