So I had a bit of a TPMS event this weekend. I see it as good and bad. First the good....I was driving down the Tunrpike here in FL at about 74mph. All of the sudden I get the TPMS warning message on the dash. I thought, Oh crap. Car was driving fine and no noise from the tires. I figured it was just a low tire, but still pulled into the slow lane(I was in the process of passing someone). Once I get to the slow lane and start to pull off onto the shoulder I could here the tire noise. It was a real flat. Darn it...I get out and see the left rear is totally flat, but in tact(no blow out, but lots of scuffing on the sidewall). I didn't really try to inspect it much, really don't want to spend too much side on the side of the road looking at the tire. So I pull out the fix a flat/compressor thing, and proceed to try it out. Get all the goop in, but no pressure is building at all...the hole is too big. So I get picked up and take the kids to soccer. I get the car towed on flatbed to a tire place that night.
In the AM, they pull the tire. And now the bad.....the tire was toast. The TPMS did not alert me early enough, and the tire was too damaged to patch. Luckily, my tire store had one in stock, and $200 later I am good to go.
So the good is thet the TPMS did alert me before I could hear or feel any issue, thus prevented the flat tire from turning into a much worse safety issue, and the bad is that it did not alert me early enough to save the tire. I can live with that.
It does make me think of buying a spare for when I travel out of town, especially in areas without good cell coverage. I would have been in a bad place if I was driving across the state with no cell coverage, no spare, and only some worthless fix a flat stuff. Makes me want to buy a new car with an actual spare, even if it is only a donut one.
