Channels for water evacuation between tread and road
Circumferential bands of tread rubber between
grooves for continuous road contact and traction, may be enhanced with
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.
Special rubber compound highly impervious to air
migration for maintaining air pressure without leaking.
Either fabric cord (passenger and lgi8th truck
tires) or steel cord (mainly truck tires) for structural strength of air
Rigid cable serving as an anchor around which body
plies are wrapped and which secures tire to rim flange area.
Special hard rubber compound extending up into sidewall
to increase flexing around bead cable and enhance stiffness of lower
sidewall for improved handling.
Layer of fabric material protecting bead area from
rim chafing and mounting damage.
