Tire Components:

Tread: The outermost layer of the tire that makes contact with the road. Tread patterns and compound composition vary to provide traction in different conditions.

Sidewall: The vertical side of the tire that contains essential information like tire size, load rating, speed rating, and brand markings.

Carcass (Body Ply): Multiple layers of fabric cords (typically made of polyester, nylon, or steel) that provide structural support and flexibility to the tire.

Belt Package: Steel belts located between the tread and the carcass to reinforce the tire, improve stability, and enhance tread life.

Beads: The inner edges of the tire that grip the wheel's rim to maintain tire shape and secure it in place.

Inner Liner: A layer on the inside of the tire that helps maintain air pressure and prevents air leakage.

Tread Wear Indicator (TWI): Small bars or grooves molded into the tread that become visible as the tire wears down, indicating the need for replacement.

Sipes: Tiny grooves or cuts in the tread blocks that improve traction on wet or icy surfaces by providing additional biting edges.

Wheel Components:

Rim: The outer circular part of the wheel that holds and supports the tire. Rims can be made of steel, alloy, or other materials.

Spokes: Metal rods or bars that radiate from the hub to the rim, providing structural support, distributing weight evenly, and contributing to the wheel's strength and rigidity.

Hub:The central part of the wheel that attaches to the vehicle's axle or hub assembly. It contains the wheel's mounting holes (bolt holes or lug holes) for attachment to the vehicle.

Center Cap: A decorative cover that conceals the hub area, often featuring the manufacturer's logo or branding.

Bolt Holes/Lug Holes: Openings in the hub where the wheel bolts or lug nuts are secured to attach the wheel to the vehicle.

Valve Stem Hole: A small hole in the wheel through which the tire's valve stem protrudes, allowing for tire inflation and maintenance.

Wheel Face: The flat surface of the rim that comes into contact with the tire bead, ensuring proper seating of the tire.

Wheel Offset: The distance between the wheel's centerline and the mounting surface (hub). It affects the vehicle's track width, handling, and appearance.

Bolt Pattern: The arrangement of lug holes on the wheel, expressed as the number of lug holes and the diameter of the circle they form (e.g., 5x114.3).

Load Rating: Specifies the maximum weight capacity that the wheel can safely support, ensuring it can carry the vehicle's weight and any additional load.

TPMS Sensor:The component that monitors tire pressure and alerts the driver if the pressure is too low.

Finish: Surface treatment or coating applied to the rim, such as chrome plating, paint, or polished aluminum, affecting appearance and corrosion resistance.

Types of TPMS Sensors:

Direct TPMS: These sensors are installed inside each tire and directly measure the tire's air pressure. There are two types:

Valve Stem-Mounted Sensors: These sensors are attached to the tire's valve stem and include a pressure sensor and a radio transmitter. They are typically found in modern vehicles.

Band-Mounted Sensors: These sensors are mounted on the inside of the wheel, and they use a band to secure the sensor to the wheel's rim. They are less common.

Indirect TPMS: Indirect TPMS systems do not use physical sensors to measure tire pressure. Instead, they rely on the vehicle's anti-lock braking system (ABS) to monitor wheel speed. When a tire's pressure is low, its rolling circumference changes, and the ABS system detects this change. While indirect TPMS is less precise than direct TPMS, it is more common in older vehicles without built-in TPMS sensors.

Components of Direct TPMS Sensors:

Pressure Sensor: This sensor is responsible for measuring the air pressure inside the tire. It typically uses a microelectromechanical system (MEMS) or other technology to detect changes in pressure.

Radio Transmitter: The pressure sensor is connected to a radio transmitter that sends tire pressure data to the TPMS control unit (ECU) in the vehicle. The transmitter operates on a specific frequency designated for TPMS communication.

Battery: Direct TPMS sensors are powered by an internal battery. These batteries have a finite lifespan and may need replacement when they run out of power.

Valve Stem or Band: In the case of valve stem-mounted sensors, the sensor is attached to the valve stem, which is then secured to the wheel. Band-mounted sensors are secured inside the wheel using a metal band.

Seal and Gasket: To maintain an airtight seal, TPMS sensors have seals and gaskets to prevent air leakage.

Functionality of TPMS Sensors:

TPMS sensors continuously monitor the tire's air pressure while the vehicle is in motion.When a tire's pressure drops below a preset threshold (typically around 25% below the recommended pressure), the sensor triggers a warning light on the vehicle's dashboard.Some TPMS systems display the actual tire pressures for each tire on the dashboard, allowing the driver to monitor individual tire pressures. If the sensor detects a significant change in tire pressure or a sudden loss of pressure (as in a flat tire), it sends an immediate alert to the driver.
