How are Car Tires Made?
Introduction
Car wheel rubber is one of the most important materials used in the automotive industry. It is a durable, elastic material that provides a smooth ride and excellent traction on the road. The production of car wheel rubber involves the harvesting of rubber from trees, a process that has been practiced for centuries. In this article we’ll talk about the process of how car tires are made and information on the tire manufacturing industry.
What is Tire Rubber Made of?
Rubber trees, also known as Hevea brasiliensis, are native to the Amazon rainforest in South America. They were first discovered by European explorers in the 16th century, and by the 19th century, they were being cultivated in Southeast Asia. Today, the majority of the world's rubber supply comes from plantations in Indonesia, Thailand, and Malaysia.
Harvesting of Rubber Tree
The process of harvesting rubber from a rubber tree is known as tapping. Tapping is typically done every other day and involves making a small incision in the bark of the tree with a special tool called a tapping knife. The sap, known as latex, then flows out of the tree and is collected in a container.
The latex collected from the rubber tree is a milky white liquid that contains approximately 30% rubber.
Processing of Rubber
It is then transported to a processing plant where it is turned into solid rubber by a process known as coagulation. Coagulation involves adding an acid to the latex, which causes the rubber to solidify and separate from the liquid.
The solid rubber is then washed, pressed, and dried to remove excess water. It is then cut into small pieces and sent to a rubber factory where it is processed into a variety of products, including car wheel rubber.
The production of car wheel rubber involves mixing the solid rubber with various chemicals and additives, including carbon black and sulfur, to improve its strength and durability. The resulting mixture is then rolled into sheets, which are cut into the appropriate shape and size for use in car wheels.
Key External Drivers of Tire Manufacturing Industry
Trade-weighted index: The trade-weighted index measures the value of a country's currency relative to its trading partners. Fluctuations in the index can impact the cost of raw materials used in tire manufacturing.
Consumer spending: The level of consumer spending can impact the demand for new tires as people may purchase new cars or replace worn-out tires.
Domestic trips by US residents: The number of domestic trips taken by US residents can impact the demand for tires as more travel leads to more wear and tear on tires.
Total vehicles miles: The total number of miles driven by vehicles can impact the demand for tires as more driving leads to more wear and tear on tires.
Average age of vehicle fleet: The average age of the vehicle fleet can impact the demand for tires as older vehicles require more frequent tire replacements.
New car sales: The number of new cars sold can impact the demand for tires as new cars typically require new tires.
