Wheel Alignment

Kenhire's latest infra-red wireless imaging equipment allows us to accurately check your vehicle's wheel alignment and compare the tracking, caster, camber and toe angles with manufacturer's data.

Many garages offer a basic two wheel alignment, but few have the ability to check all four wheels, which helps maximise your fuel efficiency, reduce any uneven tyre wear and improve your driving comfort and safety.

We supply a detailed report on all four wheels, and offer competitive prices for all necessary repairs and adjustments necessary to bring your car or van back within the specified tolerances.

What is Wheel Alignment?

Having correctly aligned wheels is important for maximising your vehicle’s road holding, prolonging the lifespan of your tyres, and even improving fuel consumption. Many things can cause wheels to become misaligned, but the most common are hitting a kerb or driving over a pot hole. You certainly need to have your alignment checked if your wheels have impacted anything. Incorrect wheel alignment will affect the handling of the vehicle and can result in rapid wearing on the edges of tyres, meaning you’ll have to pay for a replacement earlier than would otherwise be required.

The main elements of wheel alignment are camber, caster and toe:



Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When the wheels tilt outward at the top, the camber is positive. When the wheel tilts inward at the top, the camber is negative. The amount of tilt is measured in degrees from the vertical. Camber settings influence the directional control and tyre wear.

How does camber affect my vehicle?

  • Too much positive camber will result in premature wear on the outside of the tyre and cause excessive wear on the suspension parts.
  • Too much negative camber will result in premature wear on the inside of the tyre and cause excessive wear on the suspension parts.
  • Unequal side-to-side camber of 1 degree or more will cause the vehicle to pull or lead to the side with the most positive camber.



Caster is the tilting of the uppermost point of the steering axis either forward or backward, when viewed from the side of the vehicle. A backward tilt is positive and a forward tilt is negative. Caster influences directional control of the steering but does not affect the tyre wear. Caster is affected by the vehicle height, therefore it is important to keep the body at its designed height. Overloading the vehicle or a weak or sagging rear spring will affect caster.

When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a more positive caster. If the rear of the vehicle is higher than its designated trim height, the front suspension moves to a less positive caster.

How does caster affect my vehicle?

  • With too little positive caster, steering may be light at high speeds and wheel returnability may be diminished when coming out of a turn.
  • If one wheel has more positive caster than the other, that wheel will pull toward the centre of the vehicle. This condition will cause the vehicle to pull or lead to the side with the least amount of positive caster.



Toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight ahead position, obviously the ideal is for the wheels to roll parallel.

When a pair of wheels is set so that their leading edges are pointed slightly towards each other, toe is positive (+) and the wheel pair is said to have toe-in. If the leading edges point away from each other toe is negative (-), known as toe-out. The amount of toe can be expressed in degrees as the angle to which the wheels are out of parallel, or more commonly, as the difference between the track widths as measured at the leading and trailing edges of the wheels.

Toe settings affect three major areas of performance: tyre wear, straight-line stability and corner entry handling characteristics.

Toe also serves to offset the small deflections of the wheel support system that occur when the vehicle is rolling forward. In other words, with the vehicle standing still and the wheels set with toe-in, the wheels tend to roll parallel on the road when the vehicle is moving. Improper toe adjustment will cause premature tyre wear and cause steering instability.

How does Toe affect my vehicle?

  • If the wheels on an axle don’t point directly ahead when the vehicle is running in a straight line, your tyres will scrub, since they are always turned relative to the direction of travel, wearing out quicker and increasing fuel consumption.
  • Too much toe-in causes accelerated wear at the outside edges of the tyres.
  • Too much toe-out causes wear at the inside edges.
