DEFINITION

Classification: 152/543

Chafer or sealing strips:

(under subclass 539) Subject matter wherein an annular elastomeric strip that may include reinforcing material is disposed in the bead region of the tire but is not in direct contact with the annular reinforcing element.

(1) Note. These annular elastomeric strips are employed to, e.g., reinforce the turned up edge of the carcass, reduce

chafing between the tire and the rim and minimize undesirable air diffusion into or out of the tire.
