What s in a tire. Different versions are used depending on the section of the tire being constructed along with the manufacturer s specific performance requirements.

What Are The Different Parts Of A Tire Completely Firestone

The materials of modern pneumatic tires are synthetic rubber natural rubber fabric and wire along with carbon black and other chemical compounds.

What are tires made of. Bicycle tires aren t made from just one type of carbon black or silica though. The other primary ingredient in tire rubber is carbon black. They consist of a tread and a body.

Bead tire bead bundles usually strands of wire secure the tire to the wheel. Tire tire tire materials. The tire is the only part of the car that touches the road.

To this end cord materials must have high stiffness resistance to repeated flexing high strength to weight ratio and good adhesion to rubber. The first component to go on the tire building machine is the innerliner a special rubber that is resistant to air and moisture penetration and takes the place of an inner tube. Synthetic rubber is produced from the polymers found in crude oil.

Common softeners antidegradants. How is a tire made. A pneumatic tire is reinforced by layers of relatively inextensible cords that hold the air pressure and restrict deformation and growth of the tire during use.

Tires must strike a balance between traction comfort durability energy efficiency and overall cost. Passenger tires are usually made with two or three belts. The tread provides traction while the body provides containment for a quantity of compressed air.

Plies and belts give the tire strength while also providing flexibility. The tread is a thick extruded profile that surrounds the tire carcass. Take for instance a smart phone.

As a result of these competing needs tires are more complex to design and build than you might think. Carbon black is a fine soft powder created when crude oil or natural gas is burned with a limited amount of oxygen causing incomplete combustion and creating a large amount of fine soot. Tires contain many rubber compounds and other materials because they are required to safely perform in the face of a wide range of demanding conditions.

Tire cords have been made of cotton rayon nylon polyester. Next come the body plies and belts which are often made from polyester and steel. Tread compounds include additives to impart wear resistance and traction in addition to environmental resistance.

Tread compound development is an exercise in compromise as hard compounds have long wear.
