So I get my stuff ready and go to the tire and pull out the nail. The hole is in between the treads, so with the tire on the car I can't really see the hole now that I pulled the nail out. So I put a piece of tape on the tire to mark the spot, and then I proceed to take the tire off, so I can work see the hole and have some working room.
I've had this car for 3.5 years and luckily I've never had a flat or a reason to take off the tire. So the search is on for the jack and how to work it. That doesn't really take that long as the jack is under the back seat and is similar to the jack I've had with my last couple of cars.
I jack the car up, scraping my knuckles on the concrete along the way. I pull the tire and look around where I marked the tire, and I can't see a whole. That's not totally unusual, as the rubber kind of sealed back up after the nail is pulled out of it. So I pull some spit around the area to see if it bubbles. This always works with my bicycle tires, so I thought it would work here too. The escaping air will usually bubble up through the spit, and it makes it easy to find the hole. No luck this time.
I'm scratching my head a bit, but I decide to get some soapy water, like the shops do, and spray that around the area, as that will do the same as the spit. It should bubble even more than the spit. Again, nothing.
So what now? I don't want to make a hole in my tire just so I can stick a plug in there. Is it possible that the nail did not actually puncture the tire? Could it have been a superficial wound?
Oh well. So I check the pressure and it is a little low, but just barely. I fill up the tire with air and put it back on.
what a waste of time.
