Parts of the Starndard Radial Tire
Channels for water evacuation between tread and road surface.
Circumferential bands of tread rubber between grooves for continuous road contact and traction, may be enhanced with sipes.
Contact area with road surface using various compound strategies like maximizing grip or mileage.
Transition element between tread and sidewall for traction during cornering and maneuvering.
Woven steel cord mesh for rigidity of tread rubber to reduce tread squirm and increase tread life.
Compounded for high heat resistance to increase high-speed durability and sometimes fuel economy.
- Inner Liner:
Special rubber compound highly impervious to air migration for maintaining air pressure without leaking.
- Body Plies:
Either fabric cord (passenger and light truck tires) or steel cord (mainly truck tires) for structural strength of air chamber.
- Bead Cable:
Rigid cable serving as an anchor around which body plies are wrapped and which secures tire to rim flange area.
- Bead Apex/Filler:
Special hard rubber compound extending up into sidewall to increase flexing around bead cable and enhance stiffness of lower sidewall for improved handling.
- Bead Chafer:
Layer of fabric material protecting bead area from rim chafing and mounting damage.
