The guidelines for tire repair were set by the U.S. tire manufacturer association.It's pretty safe and sound guidance that the reference is designed to help sell tires.
The long and short of it is that I wouldn't fix it.It's not about money, but about safety.The steel is the strongest part.You would be opening up to failure by drilling them.
I would be willing to replace it, but not recommend it.Understanding tyres is not easy.If you have it repaired, I would say there is a 30% chance of absolute catastrophic failure, 30% chances of continual structural issues, and 70% chance nothing will happen.
It's a bad idea to let the TYRE know that it isn't sound.Your wheel may not be balancable to perfect balance if it flatters or blows out, and that can cause stress on other components, as I've seen it cause a driveshaft fail under unusual conditions.
If you can't afford them spare, replace, but if it's a space saver, repair is safer than using the spare.We consider the above diagram to be safe.This means that you would have to weaken the tire to fix it.It isn't likely to last long due to other problems.
Zipzit said that the photo is deceptive.That appears to be a tire.zipzit says that the object appears to be at about the location shown, so well off the tread proper.
The photo angle is odd.Look at that photo again.Do you see the tiny nubs?There are two rows of nubs running in the same area.The rubber mold for the tire has drilled gas escape zones.They allow gas to escape from the closing tire mold and not get trapped as a bubble in the tire.Here is the thing.The nubs would be worn off in 25 miles of travel if they were on the tread area.The fact that they are still visible is proof that the screw is at the edge of the steel belt.
The brand of tire that I would replace would give you a 1 year or 2/32 tread warranty with your local retailer.
The problem is not the holding air but the structural nature of the structure.
If the tire is in the belts and there is a small hole from a nail or screw, it can be repaired with just a patch, however most places have the plug and patch all in one.
I replaced a tire a few days ago, it wasn't fun, but I did what I had to.
