Signs of unaligned wheels
01. Increased tyre wear
Unsurprisingly, if your wheels aren’t pointing in the same direction as each other, you will experience accelerated tyre wear. The most common culprit is excessive toe (either in or out) causing uneven wear across the tyre, but too much negative camber can also cause tyres to wear out faster on the inner edges.
02. Reduced performance
To ensure the optimum performance from your car, you will need the maximum contact patch between the tyre and the road. Incorrect wheel alignment will reduce the contact patch between your tyres and the road, affecting braking and cornering performance. Also, extra effort is required to effectively push the tyres across the road if the front wheels aren’t parallel. Imagine you are rolling the wheel and tyre down a line on the road – it’s quite easy and the wheel will roll freely. Now imagine turning that wheel at a 45 degree angle and trying to roll along the same line; much more effort is required to push the wheel along the line, as it naturally wants to go off at a different angle – the same is true if a car’s toe in/out settings are incorrect.
03. Pulling to one side
Another common problem with wheel alignment, specifically the toe settings, results in the car wanting to pull to one side of the road. If the front wheels are toeing out (pointing away from each other) the car will naturally want to pull to one side, because when one wheel is in the dead ahead position, the other wheel is trying to turn a corner.
04. Increased fuel consumption
If the wheels are misaligned and require extra effort to turn them, naturally the amount of fuel the car uses is also going to increase. With the wheels aligned correctly none of the car’s power is wasted overcoming misalignment issues, and therefore fuel economy is improved.
At worst, misalignment can cause the car to feel very nervous and twitchy, especially at speed.
