Some years ago, we were preparing to leave our home in rural Mexico, and return to the States for a visit.
I went out to look the car over, and there was a low tire. A cousin volunteered to take it to be repaired.
When he brought it back, it was covered with hammer marks. The klutzes where he took it didn’t have an air operated breaker, so they hammered it off.
Several weeks later, I was motoring across Georgia at 70 mph, when my tire pressure light came on. This car actually compares tire rotation speeds, and turns on if there is a difference.
I pulled off in a safe place and checked tire pressures. All were okay.
I drove on and the light came on again. I found a rest stop and looked the tires over really well. On the hammered tire, i could tell the tire was trying to come apart,and put on my spare. When I got to my son’s house I bought a new tire.
I was convinced if not for that tire pressure light, that tire would have eventually blown up at 70 mph,
When I got back, I had a talk with the cousin, telling him that is what happens if you hammer a tire off. I found a tire repair place which uses an air pressure device to break the tire loose. I have had no more problems, though I do get a lot of nail flats here.
The tire guy does have another problem. His old itre gauge actually says 35 when its nearly 60, so he has learned to start filling it, then borrows my gauge to finish filling it.
