Wheel alignments are a standard maintenance service that you should have completed every couple of years at least. The goal is to realign your wheels back to the correct angle for optimal wear, handling, and performance for your vehicle and tires.
Upon first glance, you may not necessarily see anything wrong with your wheels/tires. However, there are subtle signs that indicate that at least one of your tires is misaligned. Uneven wear across tire treads, strange pulsating sensations from the wheel, off center steering wheel, or a pulling sensation in one direction may indicate that you need a wheel alignment.
