Tire Functions
Load-Bearing Function: Supports the vehicle's weight.
Traction/Braking Function: Transmits driving and braking forces to the road surface.
Maneuverability and Stability: Changes and maintains the vehicle's direction of travel.
Ride Comfort: Absorbs vibrations from the ground.
Tire Structure - Component Functions
Tread: The only part of the tire that contacts the ground, requiring properties such as wear resistance, traction, and rolling resistance.
Steel Belt Layer: Located between the tread and the carcass to increase strength and enhance tread durability.
Steel Ply Cord (Carcass Ply): High-strength, fatigue-resistant steel cord that supports the tire carcass.
Backup Liner: Rubber-like component wrapping the carcass ply, preventing air from penetrating the carcass.
Inner Liner: Ensures air pressure retention by wrapping the tire's interior.
Bead: The hardest part of the tire structure that contacts the rim, sealing and supporting the vehicle.
Tire Specifications
Outer Diameter: The diameter of the tire when mounted on the corresponding rim and inflated to the specified pressure, measured without any load on the tire.
Overall Width: The maximum width of the tire, including the sidewall lettering and patterns, measured in millimeters (mm).
Suitable Rim Width: The width of the rim that best matches the tire's performance. This includes:
Standard Rim: The optimal width and shape, measured in inches (in).
Applicable Rim: The range of rims that can be used with the tire.
Rim Diameter: The diameter of the wheel rim that fits the tire, which is the same as the tire's inner diameter, measured in inches (in).
Section Width: The width of the tire minus the thickness of the sidewall lettering and patterns, measured in millimeters (mm).
Tire Height: Half of the difference between the tire's outer diameter and the rim diameter.
Tread Width: The width of the tire's tread, measured as the distance between the two most protruding parts of the tread.
