Believe it or not, there’s more to your tires than the outer treads and sidewall. Though we tend to only think of what we can see on the surface, tires have a series of different components that contribute to their quality and longevity. One such piece is known as its casing. Sitting just underneath the treads, this layer is essential to the overall functioning of your tires, and it can even have an effect on their efficiency while driving. This is what tire casings are and how they affect your tire performance as a whole.



As previously stated, the casing is the layer of material located underneath the tire’s tread. It consists of a woven, threaded material that provides the tire with extra foundational support when pressed against the road. This means that the lower the thread count a tire has, the more resistance it exhibits to things like punctures—because those cords are larger. Higher thread concentrations make the material less protective, and the tire lighter and more flexible. So, when going to purchase new tires, it’s important that you find a balance between the two for the best driving experience.



Tire casings affect your tire in a multitude of different ways, most of them having to do with its longevity and smoothness of the ride. Since lowly-threaded casings are better suited for protection, these tires are better at reducing the amount of damage they receive from rough roads. This makes them capable of lasting much longer than other types. Higher thread-count tires, on the other hand, aren’t nearly as heavy, which makes them better at adjusting to winding terrain.


The type of casing that you ultimately choose will also have a large effect on the price you pay for the tires. Because of how important this component is to the lifespan of the material; it actually contributes to the majority of the overall cost. Low threads will often be on the expensive side, and high threads will be a bit cheaper since they won’t last as long.
