A burst or leaking curing bladder contaminating the tire interior or causing an abrupt pressure loss must be replaced before resuming production. Check the bladder for punctures or cut zones after every batch of tires showing inner surface defects.

Clamp ring misalignment causes flash at the tire parting line and can damage the mold. Verify the ring actuator positions and mold segment alignment before re-clamping.

Mold temperature non-uniformity causes partial under-cure or over-cure, leading to tread separation or crown cracking. Measure mold surface temperatures at multiple points and clean or replace blocked heating channels.
