Mixed

A tire contains up to 30 different types of rubber, fillers and other ingredients that are combined in giant mixers to create a black, gummy compound that is ground up at a later stage.

Shredded

The cooled rubber is cut into strips that will make up the basic structure of the tire itself. In the shredding phase, other elements of the tire are prepared. Some are coated with other types of rubber.

Building

This is the phase where the tire is built from the inside out. Textile elements, steel cord plies, beads, plies, treads and other components are integrated into a tire building machine. The result is a "green tire" (unvulcanized) whose appearance begins to resemble that of the final product.

Vulcanization

Later, the green tire is vulcanized with hot molds in a “curing” machine that compresses all its parts and gives it its final shape, including the tread pattern and manufacturer's markings on the sidewall.

Inspection

At this stage, a series of specially trained inspectors use special machinery to thoroughly check all tires and detect even the slightest imperfection before they are placed on the market.

In addition to the above process, a tire sample is pulled from the production line to undergo X-ray testing for possible internal defects or weaknesses. Finally, our quality control technicians randomly select tires from the manufacturing line and cut them in half to carefully examine every detail of their construction to ensure they meet Goodyear standards.

What are the parts of a tire?

Tarpaulins

The plies are the textile layers that form the skeleton of the tire. They are usually made with fiber cables and covered with rubber. The plies offer flexibility without deforming the tire. The next top layer of the tire is the so-called “carcass ply” which gives it strength.

Heels

They are made of high-strength rubber-coated braided steel and create a watertight compartment between the tire and the wheel rim.

Top tarpaulins

Rim plies are placed around the tire to reinforce its strength and give it rigidity. They are made from sheets of rubber-coated braided steel cable. Kevlar cord is sometimes also used for strength, puncture resistance and durability.

Flank

This is the area of ​​extra thick rubber that runs from the bead to the tread and gives the tire lateral stability. All information about the tire is printed here.

Shoulder

The shoulder of the tire is a small beveled edge that sits where the tread meets the sidewall. Its design and construction play an important role in how the tire helps cornering.

Tread

This is the soft zone that constitutes the contact surface between the rubber and the road. The tread provides cushioning and grip, and its design and composition determine many of the tire's most important performance characteristics.

Notch and groove

The tread blocks are separated by deep grooves that allow it to disperse water, snow and mud. Sipes are the smallest indentations or grooves on the tread blocks themselves. These provide additional grip and are especially important on tires designed for driving on ice and snow.

Rib

In the weakest part of the center of the tire, some models incorporate a rib that runs through its central part and serves as reinforcement.
