Symptoms & Causes of Tire Dry Rot

While dry rot is not exactly the death sentence for tires, but it can tremendously affect the performance of your car.

Unlike that dry rot on wood, tire dry rot doesn’t grow organically and can’t even spread from one tire to another. Dry rot is a specific type of tire decay, which occurs when the tire is regularly exposed to harmful substances & conditions. In that case, you have a very short time to attempt to repair the damage before it gets severe and the tire is unsafe for driving.

Due to dry rot, air escapes the tire, and it gets almost impossible to keep the tire properly inflated. Dry rot can cause unnatural rubber expansion while driving that mostly results in tire breaking apart. In most cases, tire dry rot develops leaks, holes and even blowouts. Here’re a few causes & symptoms of dry rot you must know. So let’s dive in;

Symptoms of Tire Dry Rot

  • First of all, the most prominent sign of dry rot is the cracks you’ll see running down the sidewalls. In case you find cracks surrounded by discolored rubber, it clearly means that dry rot is in an advanced stage.
  • Typically, the dry rot occurs on the sidewalls, but it may spread to the tread as well. Keep in mind! A good and well-maintained tread doesn’t indicate the absence of tire dry rot.
  • Sometimes you might not be able to detect the dry rot visually. So just try touching the surface of the tire. In case you find the rubber dry and rigid, it’s a warning sign.
  • In extreme cases, the tread might even separate from the tire. When the dry rot occurs in the front tires, the steering wheel will start to wobble when driving at low speeds. In case the tread separation occurs in the rear wheel, the whole car wobbles.

Causes of Tire Dry Rot

Ultraviolet Rays: Sunlight contains ultraviolet radiations – A.K.A UV rays. These rays can deteriorate the tire’s rubber compound by a process known as photo degradation. Tires have a polymer made up of natural & synthetic rubber that’s prone to UV damage. While the exposure to normal amounts of sunlight isn’t very much harmful, parking your car for longer in the sun will inevitably damage the rubber compound.

Age: Like every, tires age as well. Factors like UV rays, physical weathering and ozone produce gradual damage with time. When people buy an old set of car tyres in Sharjah, it’s used for several thousands of miles already, and this much overuse can cause dry rot very easily. Either being used or unused, tires will age due to the exposure to elements. Why! Because the inner lining deteriorates with age, due to the effect of oxidation by the air filled in.

Chemicals: How often you use the tire dressing? Substances like silicone & petrochemicals are the major ingredients of these chemicals. These elements dissolve the protective waxes on your tire surfaces. Due to which, the car tire is exposed to the weathering effects of air & sunlight. Apart from these, acidic rain and chemicals on the pavement other factors that play a significant role in dry rot.
