What does Kwik Fit's four wheel alignment check include?

Using Hunter Hawkeye four wheel alignment equipment, we measure 14 primary alignment angles on your vehicle. These include Camber, Caster, Thrust Line, Toe in and Toe out. Comparisons are then made against the vehicle manufacturers data for your vehicle. This ensures the vehicle is set up perfectly for you to drive.

Our four wheel alignment price covers the Hunter Hawkeye Four Wheel Alignment inspection and the front toe adjustment. Additional charges will apply if further adjustments are required. You will be advised at the time of inspection prior to any work being carried out.

Further Information

What does PSI mean?

PSI, or Pounds per Square Inch, is the imperial measure for air pressure. Your tyres will have a recommended air pressure or PSI which you should keep topped up. Under inflated tyres are inefficient and unsafe. Your tyre's recommended air pressure will be printed in your vehicle manual or you can use our tyre pressure checker tool.

Further Information

What is a reinforced tyre?

A reinforced tyre is one that has a strengthened sidewall meaning it is able to carry heavier loads. Reinforced tyres are recommended for commercial vehicles where loads are generally increased.


What is a run flat tyre?

A run flat tyre is a tyre designed to maintain enough strength in the sidewall and profile to allow your car to be driven to the nearest garage for replacement in the event of a puncture. The advantage of this is that you don't have to stop and fit the spare tyre. Run flats cannot be used long term however, and should be taken to a garage for replacement as soon as you become aware of a puncture.


What is a tyre bead?

A tyre bead is the ring of steel wire within a rubber wrapper that helps to hold the tyre to rim.


What is Hunter alignment / four wheel alignment?

Traditionally a car's steering and suspension alignment comprised measuring and adjusting the front wheels (front 'Toe' angle) only. However modern cars are built for superior comfort and performance. In order to achieve and maintain a smooth drive, the steering and suspension of all four wheels need to be checked and measured; this is four wheel alignment.

At Kwik Fit we use state-of-the-art Hunter Hawkeye four-wheel alignment equipment to align wheels with pin point accuracy. By having a four wheel alignment check carried out regularly you can reduce uneven tyre wear, increase fuel consumption and save money, while improving the handling of your vehicle.

Further Information

What is rolling resistance?

The rolling resistance of a tyre is the energy needed to keep the tyre moving at a constant speed. Tyre manufacturers strive to create tyres with reduced rolling resistance which means less energy is being used to keep the tyre moving. As a result, the vehicle is more fuel efficient.


What is the difference between a summer and winter tyre?

The tread compound and tread pattern differs in summer and winter tyres. Winter tyres are specially developed to provide improved driving performance in conditions below 7 degrees celcius. Winter tyres are not just for driving in the snow, you'll also benefit from their superior grip and handling on wet and icy roads.

Further Information

What is the importance of balancing my wheels?

Unbalanced wheels can causes premature wearing of suspension and steering components, tyres and rotating parts. You may also experience vibration causing discomfort for the driver. Correct wheel balancing can help to eliminate such issues.


What is the legal limit for minimum depth of the tread on a tyre?

The legal limit for minimum depth of tread on a vehicle's tyres is 1.6 millimetres across the central 3/4 of the tread around the complete circumference of the tyre.


What is the load index of a tyre?

Every tyre has a load index which is a numerical code that ranges from 0 to 279 that corresponds to the maximum load a tyre can carry at the speed indicated by its speed symbol. For example, a tyre load index of 76 can carry up to 400 kilograms.

Further Information

What is the speed rating of my tyre?

The speed rating of a tyre is represented by a letter of the alphabet at the end of the tyre size code. The speed rating indicates the maximum speed that the tyre is capable of reaching safely. The easiest way to check the speed rating is to check your existing tyres – the speed rating will be printed on the tyre sidewall. Alternatively, check your vehicle handbook for information about appropriate speed rated tyres for your vehicle.

Further Information

What is wheel alignment?

Alignment or tracking is a process of adjusting the angle of your wheels to the optimum position as per the vehicle manufacturer’s recommendation. This ensures the vehicle steers in a straight line and tyres wear evenly across the tread.


What is wheel balancing?

Balancing is a process that takes place whenever a new tyre is fitted to a rim to ensure that when the tyre and wheel spin, their weight is equally distributed across the whole tyre. An unbalanced wheel places more weight on one part of the tyre leading to steering wheel vibration and uneven tyre wear.


Why are the prices on the website different to those quoted in my local Kwik Fit centre?

We are committed to offering our customers our most competitive tyre prices online. Therefore, prices shown for our range of tyres on Kwik-Fit.com are exclusive to the website and may vary from the prices set in your local Kwik Fit centre. We are generally able to offer better prices online than in centre due to web exclusive offers and promotions and the efficiency savings on tyres which are supplied to order, on demand, rather than from pre-paid immediately available stock. Tyres ordered online are not available for fitting on that same day and are delivered to the centre from our National Distribution Centre for each specific order made via the website. To meet these requirements, we generally offer appointments for three or five days from the date of purchase.

Stock availability and promotions in centre and online will differ as they are managed separately.

Our centres do not have access to our online prices and are not able to compare accordingly.


Why does Kwik Fit not repair run flat tyres?

Run flat tyres are designed to keep your car on the road in the event of a puncture until you find your nearest garage but cannot be repaired due to the added strain placed on them and the possibility of sidewall damage.


Why does Kwik Fit not repair tyres that have been temporarily repaired using a foam repair filler / sealant kit?

British standard BS AU159 sets out the rules for repairs to car tyres. It defines the type of damage that can be repaired and the way that repairs should be carried out. One of the most important requirements is that the car tyre has to be removed from the wheel to check for internal damage.

Because a tyre has to be removed from a wheel and checked for internal damage before it can be repaired permanently, sealants or foam repair kits cannot be considered permanent repairs.

Kwik Fit as a company therefore are unable to repair tyres that have been temporarily repaired using any foam repair kits. This is due to the bonding of the glues used on a puncture repair, if any small amount of residue is left from the foam it will react with the glues used and we cannot guarantee the quality of the repair.
