Why Is antiozonant added to tires?

Why Do Antiozonants Turn Tires Brown?

With time the element pushes its way to the outer edge of the tire. The tire’s rubber is manufactured so that the element keeps moving towards the surface gradually and provides the tire its advantages. When antiozonants come in direct contact with oxygen, a chemical reaction takes place. The reaction leaves a brown residue and causes the tire to turn brown.

Other Reasons For Tires To Turn Brown?

Silicone: silicone does not cause the tire to bloom, just like an antiozonant. However, it is a sticky thing and can attract dust and dirt to the road, which can make the sidewalls of the tires turn brown quickly.

How Do I Get Rid Of Tire Blooming?

The task of removing bloom from the tires is quite simple. All you need to do is collect a few essentials and start with them. We can convert the entire process into simple steps so that they become easy for you to follow.

Step 1: Take a tire and rubber cleaner and a stiff bristle tire brush to remove the brown residue.

Step 2: Take the brush and remove all the dirt and debris from the rims and tires. Don’t use water in this step.

Step 3: Use a hose and rinse the tire thoroughly to remove extra dirt and debris, if any.

Step 4: Take the rubber and tire cleaner, apply it thoroughly on the sidewalls of tires, and leave it for some time as instructed in the cleaner’s manual. You can also prepare your cleaner by mixing one teaspoon of dish soap in 1 liter of water. 

Step 5: Now, take the brush and scrub every inch of the tire where there is blooming. Don’t use a steel scrub and use it very harshly as it may penetrate through the rubber and cause air leaks.

Step 6: After scrubbing all four tires, use a pressure washer to remove maximum dirt and brown residue.

Step 7: After the water has all drained, you can use a tire polish spray to make your tires shine. 

Will Blooming Reappear After Cleaning?

Yes, blooming will reappear after cleaning. This is because the antiozonants keep working even after several washings. Antiozonants keep moving towards the edge of the rubber and oxidize to produce a brown residue. This process continues till the life of the tire. Even if you seldom use your car, you can see a brown residue on the tires’ sidewalls. Hence cleaning the tires to remove blooming can be a regular task for you. 

How To Prevent Tires From Blooming?

  • It is necessary to frequently clean the tires to prevent the blooming from reappearing. 
  • Tire dressing is also an alternative to prevent tire blooming. Tire dressing creates a layer on the tires and prevents them from oxidation. Water-based or silicone-based tire dressings are available in the market. 

What Is Tire Dressing For?

Tire dressing is used to give a shine to the faded old rubber tires. They give a new look to the old tires that every car owner dreams of. There are two types of tire dressings: water-based and silicone-based. The former is a mixture of non-greasy synthetic polymers and natural oils, and the latter contains petroleum distillate solvents. 

Most of the water-based dressings are environmentally friendly and do not harm rubber over time. On the other hand, silicone-based dressings leave a wet, glossy layer on the tire’s surface. They attract more dust and grime from the road and can also be the reason behind the cracking and drying of the surface.
