provides structural support to the tire, helping it maintain its shape and strength, especially when the tire is subjected to heavy loads, such as during landing, takeoff, or taxiing. It helps distribute the load and maintain the tire's integrity

Aircraft tire sidewalls often contain important information, such as tire size, load rating, speed rating, and manufacturing details. This information is crucial for maintenance personnel and ensures that the correct tires are installed on an aircraft.

helps maintain proper lubrication within the wheel assembly, reducing friction and wear on moving parts. By creating a barrier, it also protects the wheel bearings from environmental elements, contributing to the longevity and performance of the entire wheel system.

also referred to as linings, are attached to the brake calipers and come into contact with the rotating brake discs.

Depending on the specific tread design, grooves can improve traction on various types of surfaces, including snow, ice, and loose gravel.

The (blank blank blank) is responsible for transmitting the input from the pilot's foot pedals to the brake components.

The sidewall needs to be flexible to some extent to allow for deformation and compression of the tire as it contacts the runway surface.

refers to the outer surface of the tire that comes into contact with the runway or landing surface during takeoff, landing, and taxiing.

form a critical part of the wheel bearing assembly, allowing for the smooth and efficient rotation of wheels and other rotating components.

Grooves also aid in clearing debris, such as small rocks or foreign objects, from the tire's contact area.

Wire beads also help create an airtight seal between the tire and the wheel rim. This seal is essential for maintaining tire pressure and preventing air from escaping, ensuring that the tire remains properly inflated during flight operations.

These discs rotate with the wheels and are essential for generating the necessary friction for braking.

It is a safety feature designed to prevent the wheels from skidding or sliding during braking, especially on slippery or uneven surfaces.

are used on aircraft where a single disc on each wheel does not supply sufficient braking friction. Two discs are keyed to the wheel instead of one. A center carrier is located between the two discs

During the landing and braking process, aircraft tires generate a significant amount of heat due to friction.

are an important component of a landing gear system. With tires mounted upon them, they support the entire weight of the aircraft during taxi, takeoff, and landing

It refers to the patterned indentations or channels on the surface of an aircraft tire's tread.

are circular metal rings with a small gap, allowing them to be snapped into a groove or recess on a shaft or inside a bore.

Wire beads are used to anchor the tire to the wheel rim. They provide a secure and tight fit, preventing the tire from slipping or rotating on the rim during high-stress maneuvers, such as takeoff, landing, and taxiing.

Braking is accomplished by applying friction to both sides of the disc from a non-rotating caliper bolted to the landing gear axle flange.

Some aircraft tires may have sidewall markings for branding and aesthetic purposes, which can include the manufacturer’s logo or tire branding

It is a circular metal plate that attaches to the hub of the wheel and provides a surface for the brake pads to clamp onto when the brakes are applied.

usually includes the tire and is exposed to the runway surface during landing.

typically houses the brake assembly and is connected to the aircraft's landing gear.

is a circular sealing ring made of resilient material, such as synthetic rubber, designed to create a secure and leakproof seal between the components of an aircraft wheel assembly, preventing the escape of fluids or gases.

refer to layers of fabric or material that make up the structural body of the tire, often called the tire casing or carcass.

One of the primary functions of grooves is to help disperse water on wet runways.

The typical aircraft wheel is lightweight, strong, and made from

house the brake pads and facilitate their movement.

are heavy duty brakes designed for use with power brake control valves or power boost master cylinders.

are mechanisms that redirect engine thrust forward during landing to assist in deceleration. They can complement the conventional braking system.

play a critical role in maintaining the structural integrity of the tire and ensuring that it remains securely attached to the wheel during various phases of flight and ground operations.
