1 Answers
Tire quality three guarantees coverage can be divided into tread, shoulder, and sidewall. The specific tire quality three guarantees coverage is as follows: 1. Tread: (1) Crown hole: During production, the tread is too long, not compacted, tread brushing is uneven, poor adhesion to the carcass leading to detachment, or tank flipping. (2) Crown wire exposure: The crown steel belt layer is exposed. 2. Shoulder: (1) Shoulder separation: Separation between shoulder rubber and rubber, or rubber and ply, with no obvious bulge; the separated surface is smooth and not torn. (2) Shoulder bubble: Obvious protrusion between shoulder rubber and rubber, or rubber and ply. 3. Sidewall: (1) Sidewall separation: Separation between sidewall rubber and ply, with a smooth separated surface. (2) Sidewall bubble: Separation and protrusion between sidewall rubber and ply.
