Why Tires Turn Brown

Antiozonant is an element added to the rubber which protects the tire from cracking and drying out from exposure to the elements.

However, antiozonant can also cause browning in the tires. Tire browning is often called tire blooming. This can be prevented when you thoroughly clean and protect the tires.

Mold release agents and silicone may contribute to the tire problem, but neither are the primary cause.

Mold Release Agents

Mold release agents that are used in tire manufacturing do not directly cause browning. However, they can worsen the problem because they keep the antiozonant on the tire surface. The more that is left on the outer tire surface, the more oxidation takes place leaving brown deposits.

Mold release agents are the non-stick lubricants in tire molds. These may remain on tires, contributing to the blooming effect after weeks of a long drive.

Silicone

Browning caused by silicone is different from blooming. Silicone is a sticky element that can allow dirt and dust to hold on to the tire surface. It turns brown in color eventually.

In this case, regular cleaning using a clean cloth, brush, and water. You may also remove the dressing with scrubs and special degreasers.

What is the real cause of tire blooming?

Before we deal with the main problem, let us first understand its cause.

The myth: Tire blooming occurs because of tire products or the tire dressing. Some people suggested that tire products can degrade the quality of tires over time and leave a brown color.

This makes sense but it is not quite true.

The actual cause is really the tire itself. Tires may seem like rubber lumps, but they are highly specialized pieces of equipment. Manufacturers have multiple compounds which are added during tire production, and one of these is the antiozonant.

Unfortunately, antiozonants can also respond to outside elements such as air and water. They combine and work to disintegrate the antiozonant. That breakdown leads to the brown discoloration of the tires.

Quality tire products and dressing stop the process by creating a barrier between the tire and the antiozonant including the outside elements.

Having a barrier means slowing down the degradation process and may completely prevent it with consistent application. Tire dressing not only gives you a fresh black color but prevents the tire from decaying over time.
