Here's my recent "never made a call for tire roadside assistance" experience:
After stopping at Ben & Jerry's in Vermont, was on the Interstate headed toward Burlington, cruising with traffic at 65 mph. Suddenly, big noise fills the van... Get the camper stopped at side of the road, shoulder hardly as wide as vehicle, and thick growth knee high beyond pavement. Heavy traffic zipping by. Tire blew out - had just 3000 miles on it.
AAA (claimed they) called every one of their contractors in area - none would come out on the Interstate to change a tire - "too dangerous." They also wouldn't come out to tow me in when AAA tried that tack after two hours fiddling around. With that, I changed the tire myself (hsould've done it anyways) and we limped to town on the doughnut.
Next morning we go to the local tire store that happened to sell the same brand tire (Falken). The service guy looked at the chewed up tire and we both wondered what caused the catastrophic failure. Hadn't hit or driven over anything. (BTW, I used to sell tires, so I think I know something about them.) And there was no warning.
After the tire was dismounted I was called over. He showed me something I'd not seen before. It was the pressure sensor that attaches inside with the valve stem. The metal stem apparently fatigued and broke off - then WHOOSH! He said such a failure is not unusual, that the tire installers generally don't bother to check when new rubber is installed. (I had been getting intermittent low pressure light on the dash, but the pressure was fine in all four tires when I checked them.) The metal stems are easily replaceable, and only cost a few bucks, if not included.
So, my cheap advice, don't count on "help" ever arriving, even for a tow, if stranded in the wrong place. I always carry a plug kit and tire pump (I find the Wal-Mart Slime-brand pump with integral gauge and light the best I've ever used. Quick to inflate a tire even from zero. Bargain at about $20.) And my lesson learned: Have those metal valve stems checked when new tires are installed, or if getting a seemingly "false light."
BTW: Shout out to the lady on the phone at the nearby Wal-Mart. The store does not have a tire department. Nothing was open otherwise after 6 PM. She wished me luck, and then, "If you can get your camper here, you're welcome to stay overnight in our parking lot." Bless her for trying in our time of need.
