Tire manufacturer · Four programs

Engineered for the contact patch

Global Rubber Industries makes tires for passenger cars, light trucks and SUVs, commercial trucks, and off-highway and industrial equipment. Every program starts where the tire meets the ground.

01 / The contact patch

Everything a vehicle does reaches the road through four patches of rubber.

Each patch is roughly the size of an adult's hand. Acceleration, braking, steering, and the full weight of the vehicle and its load all pass through them. That is what we design around: the compound that grips, the tread that clears water, and the structure that holds the patch in shape.

Recommended pressure: the load spreads across the full width of the tread and the patch keeps the shape the tire was designed around.

03 / Construction

Seven layers between the road and the air inside.

A radial tire is built up in layers, and each one has a job. Scroll to take one apart.

04 / How a tire is built

From latex and steel to a cured tire in five steps.

Natural rubber starts as latex tapped from the bark of the Hevea tree. In the factory it joins synthetic rubber, carbon black, silica, oils, and a cure system, then steel and textile cord.

  1. 01

    Mixing

    Rubber, fillers, oils, and chemicals are blended in internal mixers. The curatives go in last, at a lower temperature.

  2. 02

    Components

    Extruders shape tread and sidewall profiles. Calenders coat steel and textile cord with rubber.

  3. 03

    Building

    The parts are assembled on a building drum into an uncured "green" tire.

  4. 04

    Curing

    Heat and pressure in a mold vulcanize the rubber and form the tread and sidewall markings.

  5. 05

    Inspection

    Finished tires are inspected, most passenger tires are checked for uniformity, and samples go to X-ray and lab tests.
