Push through tire plugs are a polarizing subject for tire people, with the overwhelming consensus of tire manufacturers that they are temporary "hardship" or "emergency" repairs where the tire is a highway use tire. I agree with that and am not interested in debating it.
However, that said, there is certainly a place for them in those hardship or emergency cases, particularly when off road or where proper repair sourcing is not possible. I get it.
The SINGLE most important function when using a push through plug is finding and following the path of the original injury. Failing to do so frequently produces a second injury which is open to pressure that allows air migration into the belt package, body ply(s) or presents as a leak around the plug (best of the scenarios)
Safety Seal has been making a rope type plug for decades, they are effective within the limitations of their application.
The tire guy in me is now going to ask/strongly suggest that you have any push through plug that you may from necessity or convenience need to install in a on highway use tire, correctly repaired and the tire inspected as soon as possible for your safety and the safety of others.
*DISCLAIMER:
I understand that your anecdotal experience with push through plugs
garage flooring glendale, Draino, Bars Leak, witch doctors and Democrats may be positive. I don't care, they are all short term treatments that will ultimately fail you given a wider experience rate.
