Can a Run-Flat Tire Be Repaired After Being Punctured?

[DiPaisley]

Whether a run-flat tire can be repaired depends on the extent of the puncture. In normal cases, punctures on the tread can be repaired. Run-flat tires cannot be repaired under the following circumstances: 1. The puncture hole is too large, exceeding 4.2 millimeters. 2. The puncture is located on the sidewall and cannot be repaired. 3. The tire was damaged while driving after being punctured and losing air. 4. The tire has already been repaired twice and cannot be repaired again. Additional information about run-flat tires is as follows: 1. The technical name for run-flat tires is "self-supporting tires," which can still be used normally even when they lose air. 2. The biggest advantage of run-flat tires is that in the event of a tire leak, even if the air pressure is completely lost, they can still continue to drive at a speed of 80 km/h without the need for immediate tire replacement.
