sidewall pinhole repair?

MoparLeo said
Never attempt a s/w repair on a passenger tire.
The true cause of failure often requires the tire to be dismounted and inspected from the inside.
Not a defect for sure.
A damaged tire.A pin hole is much different than a broken cord.
A pin hole can be repaired with a special glue for the liner which is the actual air bladder/tube portion of the tire.
Made of impermeable rubber to hold air. the cord holds the load.
Broken s/w cord= junk tire.
Low profile( short sidewall) tires are very prone ot impact breaks. Just run over any thing like a pot hole, train tracks etc.. at too high of a speed or too low of an air pressure and the s/w will get pinched for a miilesecond between the rim and tire.

I removed the tire and I saw a witness mark on the inside, looked a little like a bubble in a casting? I'm not sure if a cord broke as the van just completed a 900 mile trip with no ride issues. These sidewalls are pretty flexible as its a 65 series tire. If the special glue can be used as a repair, is it feasible? The inside of the tire sidewall had intersecting lines in it from the mold process, do you suppose the cords line up with those raised lines? The inclusion was right between these lines. Very strange puncture, looks like it was a casting flaw if you could compare it to an aluminum casting. We already got 2 new tires for it, put the 2 best old ones on the back.
