Tire wear due to misalignment can be a major issue - one that can cause significant damage to your tires in a very short amount of time. This is especially true for issues with the toe angle, which affects the direction of the wheel's point in relation to the car's body. If an alignment problem is severe enough, it won't take long to see the effects on the tread depth of your tires. You can even spot a problem without having to inspect too closely - just by looking at the wheels from a parked position, you may be able to tell whether or not they are parallel.
