To make a long story short, on a day trip out of town yesterday I came up to the aftermath of a horrific accident with crash debris heavily littering the road. An officer was emphatically directing traffic to drive through so approaching emergency vehicles could get to the site. Like other drivers I tried to thread slowly through all the debris but could tell I had picked up something in at least one tire. I made it into the nearest small town, hunted up the only tire shop and had the tires checked.
Both right side tires had punctures about like a very large nail would cause with the debris still embedded. The tire man first put some soap on to verify there was air leaking which definitely was. Wheels were dismounted, tires removed from rims, tires patched on the inside (not plugged, but patched), tires remounted and back on car. Of course, I will keep a close check on tire pressure of all tires even more than my normal weekly routine. The tire man said I should still get full normal use from both tires.
Tires had ~12,800 miles when damaged and I drove the 90 miles back home with no problems.
Tires are the original Michelans when I bought the Camry new last year.
I know a properly patched tire can have a long life, having a few previous encounters with nails. But I do have one concern this time. The tread of one tire had the surface very slightly damaged around the puncture hole. I can best describe it as looking like a lot of hangnails in need of a manicure. This small spot of minor shredding was only perhaps a quarter of an inch deep at most covering an area of a large thump print. For SAFE use tire longevity, should I be concerned?
Side note: The crash that had all the debris in the road appeared to be from a car passing in a blind no passing zone and meeting a semi tanker truck head on. Not much left of the car. Add this to the discussion thread ongoing about why such drivers are still alive. I doubt this one was.
