the worst possible situation?
You loan your car to a group of nuns that go up the mountain for a day of fun. On the way down, they decide to exceed the speed limit, the tire blows out, and the car full of nuns goes careening of the side of the mountain and lands on a schoolbus full of preschoolers admiring a den of baby seals. the explosion kills everyone and sets the mountain on fire- destroying countless homes.
but more likely is that the needle didn’t cause any damage at all. AS has been suggested- recheck the air pressure in a few days, and if low, get to a tire shop for further diagnoses. Tell them there is a slow leak and to find it. They may find some damage at your needle hole, but I’m with others that have said that they don’t see how a little needle can cause an real issue.
and for the others: I once found a 7/16"s wrench in one of my fleet trucks tires. It wasn’t a Snap-on or a mac, so i didn’t try to save it
