“The stabilizing chemical, carbon black makes the tires black. It prevents damage from UV light, draws heat away from parts of the car that tend to get hot when driving, and makes the tires durable.”
The black color of tires comes from carbon black, a readily-available material that provides greatly improved wear characteristics and heat-dissipation capabilities when added to rubber compounds. Natural rubber is off-white in color, and in fact the first rubber tires were white.
Why are black tires so boring?
While black tires might be considered boring, there is a good reason for their color. Fully white tires, which are usually found on classic cars, are a thing of the past due to their bad durability. Therefore, tire manufacturers had to come up with better rubber blends to increase their performance and tread life.
What is carbon black in tires?
Carbon Black is a crystalline form of carbon, formed by the incomplete combustion of carbon products such as coal. It is used in industries as a color pigment and strengthening filler in tires. Some people think that carbon black is added to rubber tires just to give them a darker look.
Why do tires have a back color?
The chemical compound is the primary reason for the back color of the tires. It is a stabilizing chemical that is mixed with other polymers to produce the tire’s tread. It significantly prolongs the lifespan of the tires and protects them from the corrosive effects of ozone.
Why are tires white?
Early tire makers also often added zinc oxide to their natural rubber as a way to strengthen the material, resulting in white tires. But at some point, tire manufacturers decided to go darker.
Why do tires get dirty?
Tires bloom because antiozonant pushes its way to the outer edge of the rubber casing with time. As the element comes into contact with oxygen, it leaves a brown residue on the surface of the tire. Antiozonant is organic and helps tires last longer as it slows deterioration due to oxidation.
Why do new tires look dirty?
It is pretty normal if your new tires look dirty because of antiozonant. This is because antiozonant is an element added to the sidewalls of tires to prevent premature cracking and drying. Due to this element, the tire looks brown, which is also called blooming. To know more about it, read ahead!
Why are my tires not blooming?
Tires do not bloom because of silicone-based tire dressings. Silicone is sticky, so it may allow dirt and dust to hold on to the surface of the tire as you drive, which makes tire sidewalls turn brown. The tire becomes dirty but doesn’t bloom. In this case, you can remove the color with a simple clean, using a brush and some water.
Why do tires turn brown?
Tire sidewalls turn brown mainly because of an element added to the rubber called antiozonant. It saves tires from premature drying and cracking due to the process of oxidation. Tire browning is usually called blooming. It’s a continuing process that can be prevented by thoroughly cleaning and protecting the tires.
Can mold cause tire blooms?
As we know, the cause of tire blooming is antiozonants reacting with the outside environment. Mold doesn’t contain antiozonants, although very occasionally, the mold can cause a build-up of antiozonants on the surface, because they will cling to the mold itself.
Why can’t tires be white?
Although natural rubber is milky white, both road tires and racing slicks are black. But when automakers first started using rubber tires, they were white. All tires today are black because of a key ingredient required to make them effective.
Why are black tires still white?
Under the black layer of carbon-rich rubber the sidewalls were still white. Carbon black was needed for surface durability and so manufacturers only added it on the outside. This meant that damaged black tires in the first half of the 20th century revealed a good old white rubber, which was a real eye-sore.
What are all-white tires?
All-white tires were not a sign of wealth or luxury in the early days of the automobile. Tires were originally a beige color, until manufacturers started adding zinc oxide to the formula to provide a bright white appearance. In 1910, BFGoodrich was the first company to utilize carbon black in its rubber formula.
Why do cars have white rims?
These vehicles began by using a thinner stripe of white to match the aesthetic of speed. For hot rods and muscle cars, whitewalls soon gave way to white letter tires or plain black sidewalls. This helped put more emphasis on the wheels themselves, usually a sport design in chrome, like the Torq Thrust from American Racing
Why are whitewall tires so popular?
And because many tire manufacturers wanted to reduce costs, they only used the black compound in the tread, leaving the sidewalls with their natural white compound. With that, the iconic whitewall tire was born. Over the next several decades, the two-tone appearance of whitewalls became a standard for luxury vehicles.
Why aren t tires white anymore?
White wall tires began to disappear from the market when manufacturers began to decrease the height of the tires. The thick white stripe along the sidewalls did not allow tire brands to create tires with lower sidewall profiles. For this reason, entirely black tires became popular.
What are whitewall tires made of?
Nowadays tires are made from completely black rubber and white lettering is made using dyes. White lettering was achieved by peeling away the layer of black rubber. ( Christopher Ziemnowicz, Wikimedia) Whitewall tires grew in popularity and suddenly became more expensive than entirely black tires.
Why do tire sidewalls have white letters?
When tire sidewalls were fairly generous white walls (the thin variety) and white letters were a way to visually break up a large sidewall giving it a more athletic look so to speak. As t… Something went wrong. Wait a moment and try again.
What kind of tires were made from carbon black?
Using carbon black only in the tread produced tires with inner and outer sidewalls of white rubber. Later, entirely black tires became available, the still extant white sidewalls being covered with a somewhat thin, black colored layer of rubber.
Are car tires dirty?
Tires are usually the dirtiest parts of your car, but regular cleaning is an important part of preventative maintenance. It removes any buildup of brake dust, road grime and other elements that could potentially damage the tires. Your choice of cleaning product is equally important.
Do new tires get dirty?

Soak the tire brush into the wash bucket and start agitating the tires to clean all the dirt and grime from them. Also, you’ll remove all the old dressings. Take a long wheel brush, soak it with soap and start cleaning the wheels. Make sure to thoroughly clean them, and try to reach inside the wheel barrels as much as possible.
What is tire dry rot?
Tire dry rot, also known as sidewall weathering, is a crack that’s visible in the tread of a car tire or in the sidewall. When a tire’s rubber compound starts to break down that’s when you can usually notice any cracks. Tire dry rot is decay that happens to tires as they age, or when they’re constantly in harsh environments.
Why were tires white?
The History. When the first automobile was invented, it’s tyres were made from natural rubber. Chemicals were then added to make them tougher and more durable. A white substance, zinc oxide, was added to increase traction and it also gave the tyre a white appearance.
Why were tires white when they were made of rubber?
Tires were white when they were made of natural rubber as that is the color of rubber. Around World War 1 (1917) they started adding carbon black, a industrial byproduct, to the rubber as they found that the tires longevity increased from about 5000 miles to 15000 miles. They also found that the tires were easier to keep looking good!
Why are whitewall tires so dirty?
The trouble began soon after manufacturing – whitewall tires had to be wrapped in paper in order for them to reach the dealerships while still clean. That didn’t matter though because they became dirty when getting mounted on the rim. Then they would be dirty every day, driving through gravel, touching curbs and splashing puddles.
Is it OK to use tire black?

Why are tires blue?
There are a lot of oils used in the production of a tyre, and the blue colouring is a sign of those oils rising to the surface of the rubber where it has been worked too hard. Gary explains: “You get blue-ing where the tyre’s got too hot, either through ambient temperatures, pressures, surfaces – or all three factors.”
What is the Blue Stuff on my tyres?
The blue stuff is actually a soap stuff that they put on there to protect the white lettering in transport so it won’t get damaged and look as good as it can look when you finally get the tyres on your car.
Why are tires black in color?
The black color of tires comes from carbon black, a readily-available material that provides greatly improved wear characteristics and heat-dissipation capabilities when added to rubber compounds.

Why are my tires turning brown?
Tires contain a chemical in the rubber that aid in the UV blocking and this is what is actually turning the tires brown. That is why using a strong cleaner on tires may not be a good idea — you’ll be stripping the rubber of this product which could lead to dry rotting. That is what silicone does … dry rubber out.
Why aren’t car tires colored?
With so many colors in the rainbow, do you ever wonder why tires are always just plain black? Cars themselves come in dozens of hues, but not tires. The rubber that tires are sourced from is a milky white color, but carbon black is added to the rubber as a stabilizing chemical compound and makes the tire black.
Why are tires carbon black?
It wasn’t for cosmetic purposes. Carbon black—an elemental carbon made from the incomplete combustion of gas or oil and collected as particles—increases a tire’s durability, in part by blocking damaging UV rays that can cause rubber to crack, and by improving road grip. It also improves tensile strength, making tires more resistant to road wear.
What color are tires?
With the possible exception of some Big Wheels or other child transportation vehicles, most tires are black. You’d be hard-pressed to find a tire shop and come across a Goodyear or Michelin sample that’s any other color. Natural rubber, however, is closer to an off-white shade, and early-model cars sported that lighter color.
Why aren’t coloured tyres used any more?
– Dyler Why Aren’t Coloured Tyres Used Any More? Even though tyre manufacturers are constantly demonstrating different concepts, the end products rarely give drivers hope that the rubber on their wheels will finally look a bit more original. The differences between the tyres currently being produced are in their properties.
Why don’t we have colored tires?
Coloured Tires Don’t Last As Long Despite being a neat concept, coloured tires simply are just not as durable. For example, cars that are not treated with carbon black are good for about 5,000 miles before needing to be replaced. Tires made with carbon black can be driven for 50,000 miles or more.
Are colorful tires harder to make?
Some tire makers have made attempts over the years to add a dash of color to the familiar black donuts found on each corner of your vehicle. But making colorful tires seems to be harder than it looks. First, a bit of history.
Why are carbon black tires better?
The tread and belt areas of a tire become hot at the time of driving. The carbon black absorbs that heat quickly and returns it to the road, protecting those areas. As a result, the tires offer a more reliable drive because this element makes them stronger and more long-lasting than tires without the carbon black.
Do all tires have colored dots?
Some, but not all, tires have these colored dots when they’re new. If you look for answers on internet as to what these are for, you’ll find plenty of videos explaining that a properly mounted tire must have them aligned with the valve stem. However, we discovered they just aren’t necessary anymore to properly mount the tires.
