Here is the Composition of Airplane Tires

Main materials in an aircraft tire

A modern airplane tire is made from several layers of different materials, not just rubber.

The main components are: 

Rubber compounds (synthetic rubber)

A special blend of synthetic rubber is used for the tread and sidewall to resist wear, heat, and ozone.

The rubber must stay flexible even at very low temperatures when the plane is at high altitude, and still strong at high temperatures during landing. 

Cord plies (fabric reinforcement)

The “body” of the tire is built from many layers of rubber-coated fabric (carcass plies), which give strength and support the big weight of the aircraft. 

Older tires often use nylon cords, while newer or high‑performance tires may use tougher materials such as aramid (a synthetic fiber similar to Kevlar). 

Belt plies in the tread area

Under the tread, there are belt plies made of high‑strength cords (often nylon or high‑modulus fibers) that help keep the tread rigid and protect the inner layers from damage. 

Bead and apex (metal + stiff rubber)

The bead is a ring of steel wire wrapped with rubber, which holds the tire tightly against the wheel rim. 

An apex strip (triangular stiff rubber) helps transfer the load smoothly from the rigid bead into the flexible sidewall. 

Innerliner (for tubeless tires)

A special rubber layer inside the tire reduces air leakage, so the tire can stay inflated for long periods without a separate inner tube. 

Filler and chafing protectors

Small strips of rubber and fabric (chafer strips, protectors) are placed between layers to prevent rubbing and damage between the cords and the wheel.
