In the present era, as you drive down the road, you’ve likely noticed that the tires of all vehicles are uniformly black. It may surprise you to learn that in times past, vehicle tires were predominantly white. The transition from white to black holds an intriguing history, with roots dating back to the introduction of trains. But what led to the shift in tire color, and why were tires once white? Let’s delve into this captivating journey through time.
Earlier Tires:
In the early days, wheels were crafted from wood and coated with iron. The middle of the 19th century witnessed the discovery of rubber, marking a transformative moment for tire construction. As technology advanced, wooden wheels gave way to rubber tires, and innovations became the norm.
Tire Color:
Originally, tire color was white, reflecting the color of rubber, which was naturally yellowish-white. To enhance the strength and grip of rubber, zinc oxide was incorporated, causing tires to adopt a white hue. However, these white tires were not durable and faced a rapid deterioration. The breakthrough for this issue emerged in the early 20th century.
Black Tires:
In the late 18th century, companies recognized the quick wear and tear of white tires and sought a solution. By the end of the 19th century, the remedy was discovered. According to the Korean car manufacturer KIA, rubber was mixed with soot instead of being left empty.
The high carbon content in soot turned the tires black, not only changing their color but also enhancing their wear resistance. Consequently, the longevity of tires improved significantly—from lasting up to 5000 kilometers, the new black tires could endure more than 15000 kilometers.
During the 1920-30s, companies experimented with white wall tires to add a touch of distinctiveness. These tires featured a black surface touching the road and a white sidewall. However, this fashion trend in tire design did not persist in the market for an extended period.
Conclusion:
The evolution of tire colors from white to black is a fascinating journey rooted in technological advancements and the pursuit of durability. What was once a nod to the natural color of rubber transformed into a practical solution, giving us the ubiquitous black tires we see on the roads today.
