In your opinion.
In my younger days, service staions routinely plugged tires from the outside. That was the way it was done.
Not only in my opinion.
As said, this way of patching a tyre is now only legal as an emergency repair and you are allowed to go to a repair shop at reduced speed.
If you do this here and police stop you, you will be written a fine and the car will get a driving ban until the tyre is replaced of fixed properly.
Back in the day brakes also contained asbestos, but also there, "we" found out, that this was a bad idea.
"We did it like that, back in the day" is not the same as "This is a good idea", sometimes it is just "This was the best we knew how to, back in the day"
I carry an inflator and two types of plug kits.
I plugged one of my tires at about 18,000 miles. It now has over 45,000 miles on it. I drive 75-80 mph on the Interstate with no worries. At the worst, the tire could develop a leak. It's really not going to cause a catastrophic blowout that wipes out multiple vehicles on the highway.
Just another opinion.
Here, if you were to cause an accident and you had your tyre fixed like that, the insurance would be coming after you to get the money they had to pay to the other parties involved, if you do illegal stuff, and this causes an accident, it's all on you.
Back in the day when i was a kid i was probably driven 45.000 miles in the back of my parents cars, i never wore a seatbelt and i still survived....
But that's not a good excuse for not having the kids in seatbelts today.....Much in the same way as "I have lucked out with a bodge repair job on a tyre that has not given me problems for many miles".
But then again.....Watching some Youtube channels it seems that the general state of cars in the US, is far worse than here, partly because there are a lot more poor people, that can not afford to keep their cars in good working order, and partly because it does not seem like there are much in the way of regular inspections.
Oh yeah, we have mandatory inspections every 2 years....If the guy doing the inspection sees one of those patches you use, in a tyre, it's an instant fail.
