Knowing when to change your tires is crucial for the safety and performance of your vehicle. Here are some indications that your tires need to be replaced. Most tires have a tread depth indicator bar that is molded into the tire. When these bars become even with the tire surface that is a sign that you need to replace the tire. Another sign is uneven tread wear across the tire. Which indicates that you have some type of alignment or suspension issues. In this case you should have things like the ball joints or tie rods checked. If you experience your vehicle not handling or breaking the same this could be a sign that your tires are no longer providing optimal traction. Lastly are seasonal changes some people like to switch tires during the season. For instance, winter tires perform better than just a straight highway tread tire.
