The post Can You Plugged A Tire That Has Been Patched Already? It is true that the safety and the standards of integrity in a tire repair are very important. To apply a patch to an already plugged tire, one has to consider the ramifications in light of repair techniques and safety guidelines (and) long-term implications.
What you should do to Get Your Tyre repaired
Plug-Only Repairs: In this style of repair, a woven cord plug is inserted from the exterior into puncture site. Although it effectively stops the leak there and then, because damage is still internal to the structure of a cell or battery sufficient moisture can potentially penetrate with air (Oxygen) causing deterioration fairly quickly. This method is not approved by the National Highway Traffic Safety Administration (NHTSA) as it can lead to tread separation and blowouts12.
Repair Patch Only: This method requires the removal of a tire from its rim in order to properly retain and seal around an inside patch. This approach is more secure than plug-only repairs, but the external aperture still remains vulnerable to outside elements23.
Repair Combination: According to the NHTSA, this is the only method that will safely repair a puncture. This means both a plug and patch then filling the inside to seal it up, as well repairing any hole in sidewall. This technique significantly reduces the chance of further tire failures25.
The Risks of Improper Repairs
Tires that have been repaired with a plug are especially tricky. If the plug broke, or there is already some damage in the tire, any additional repair will only compromise further that structural integrity. According to industry standards, no tire with an improper repair should ever be repaired again; instead it is regarded as scrap in order to avert catastrophic failures14.
Costs of Ignoring Repair Standards
Cases exist where vehicles got new tires or inadequate repairs leading to blowouts, which were the driving force for serious accidents. In these examples it shows why we always tell people to follow the repair methods exactly12. Moreover, tires with repeated incorrect repairs can negate warranties and eventually add up to costly replacements56.
