Found this thread and have a quick question. Nail for me is three inches in front side. I think patching is fine but this would be used on the track. My alternative is to use new tires on a track day tomorrow. Seems like the first is a better idea but I know you know way more about this than me.
Thanks.
Thanks.
Generally -- though it depends upon the tire maker -- if the hole is small (1/4" or less) and in the tread and the tire is in otherwise servicable condition (driving the tire underinflated can ruin the tire even if the hole is repairable) -- the tire can be repaired.
IIRC the preferred method of repair is a patch which of course is applied with the tire removed from the wheel.
Now if the tire maker believes there is no acceptable repair that the tire is compromised by the hole then all you can do is replace the tire and perhaps the other tire on that end of the car as well if the undamaged tire has experienced 30% or more wear.
In one case both a damaged tire replaced and the other tire undamaged was also replaced at the same time and with only 15% wear. This was done by, and paid for, an insurance company. So even this 30% wear is variable. But IIRC Porsche says 30%.
Sincerely,

The tire maker should have guidelines regarding what damage can be tolerated and the tire repaired to return the tire to service wtih no compromise in the tire's integrity, ability to perform as good as before.

Blast of a day and I have to lost some track questionable later today on another thread.

Quick update. Tire has been patched and has functioned flawlessly with 1200 miles of street driving. Dealer is giving me a new tire as part of the wheel and tire insurance so I would only have to spend for the one additional rear when it is time to replace. Thanks for all the input guys.
