A tire’s sidewall component plays an important role when it comes to choosing new tires for your vehicle. After all, it’s impossible to know exactly what you’re buying unless the tire company provides enough detail. As the driver, you should understand what the sidewall can offer. Read on to learn the purpose of a tire sidewall and how to pinpoint this part on your own tires.

Which Part of the Tire Is the Sidewall?

To properly discuss the function of a tire’s sidewall, it’s crucial that you first identify this section. You can find the sidewall along each outer surface of the tire. It is comprised of the same rubber material as the treads. It sits directly over the inner cord plies and often exhibits markings in the form of brand names and numbers. This makes sidewalls fairly easy to notice—especially during the tire selection process.

What the Sidewall Does

One of the primary purposes of a tire sidewall is to act as a canvas that displays all the necessary information about that product. A sidewall can communicate the brand name, tire type, size, rating, or even how that item was constructed. It can convey an entire manufacturing history with just a few letter and number combinations. If you know how to understand these markings, they can tell you all you need to know about that model. Tire sidewalls have a functional role as well. By providing the tire with an additional covering, they’re also useful in increasing its overall stability and strength. They prevent debris from impacting the cord plies, making the tire much safer to use. There are a lot of different components that go into the construction of high-quality vehicle tires.
