Staying off in the summer and coming on as soon as the temperature drops And being a &*%$$# pain in my ass???? What's been the most common fix? What's been the most common fix?

Putting more air in the tire when the TPM system alerts that air pressure is low has been the common "fix" most owners use if the issue is ambient air temperature related. Unless they have another issue like a failing battery in one of the sensors or a cracked/bent wheel or tire that has a leak...a drop in ambient temperature can affect tire pressure. It’s simple sciencetific gobbledegook that I won't even attempt to explain. :)

Time to change out the summer air for winter air..

Some mechanics run a special on this around this time of year..
May be able to get a deal if you bundle the blinker fluid replacement..

:dunno:

Tires loose about 1psi per 10° F. What are the pressure readings when the light came on?

Most cars have a reset procedure to calibrate the pressure when full, I don't have on my car but check the manual.

Challenged?

Carpentry nail in between the threads... undetected.

*UPDATE*
Carpentry nail in between the treads... undetected because you couldn't see it...

A) What OTHER kinds of ‘nails’ are there?

B) Always thought the TPM system detected low AIR pressure. First Ive heard it senses nails....

;)

There's only one type of nail used for everything in the world [emoji289] one size NOT! :-)

Carpentry nail as in finishing nail: no head hardly [so as to be hidden below surface and then covered] with wood putty and then painted over[hidden]

This is why it went unnoticed. Not only did it have such a small head, but it was in between the treads of an 8/32 tire...
You couldn't see it.
I told the shop to take the tire off and check everything before I spend upto $300 for a Continental run flat...

Unless you still could see the head of the finish nail, it's quite likely the head was just worn off. Several times I've found a nail or screw that no longer had a head.

Two of my tires had "temporary" screw in by hand (brilliant repair kit) patches for 1000s of miles. I left the first one on as a test of goes long it would last and after 7-8 months another you're pocket up a screw b so that tire has a hand screwed plastic "temporary" patch for a month or two. Now those tires are worn out.

"Worn out with prejudice" to borrow a legal team. Discovered the tire was worn when it started to unravel and thwap the wheel well.

Fortunately run on flat tires I didn't have to remove 800# of stuff from my trunk to change tire and drove the 35 miles home since the tire was still holding air wasn't too concerned.

Already put new rubber on but what's the name of the plug kit just for future reference? BTW the shop that found the nail told me they couldn't repair it because it was a run flat...

Just FYI...


the 'rules' around run flat repair vary with Mfg.


It is my opinion that these are driven NOT by the technical question of "can it be repaired" but are in fact driven by "if we say it can be repaired and some idiot drives on the flat tire, damages the carcass, the shop misses it and they go out and die and we get sued" question


Michelin allows repair of their RFTs.


Ive repaired RFTs without issue.

FWIW


You can see their rationale here: So if you never drove it flat...it was just a leak...it never reached the threshold for their stated reason for not allowing repairs




Edit: Oh, per chance, did they helpfully "dispose" of that useless tire? Ebay here it comes! ;)

If never actually driven on flat there is no reason reason it couldn't be repaired but shops may not be able to do due to mentioned liability issues.

Here's the "speed plug" kit I used on a couple of my tires and to help out a stranger once I saw driving 3 mph to limp off the road to a parking lot.

They worked fabulously for me I wish I took a pic of the one that was out on the tread block it just looked like part of the tire like if there was a splat of red mixed in with the rubber.

The first time I used in a tire that didn't have a ton of tread left so I figured I would do a real world long term test and see how long it would last and apparently "indefinitely" was the answer.

I put some form of lubrication on when I installed to help the threads form tightly on the rubber and the two I used on my car worked great.

FYI: steel screw will work great in a pinch to seal a typical tire puncture to get you home.

Just take out the nail or screw and replace with a slightly bigger flat head screw. That was my go-to emergency repair and I've done that 2-3 times to get me to Sam's club who will do a proper patch-pkug no charge for advanced members.

I was trying find the photos where I pulled out a leaky screw and put in a tight one. I took out a pan head screw and replaced with a wide flat head cement board screw. Worked perfectly fine for a few days until I got to the repair shop.

Found the basic one (no mini prybar) on Amazon. I keep some of these in each car glove box. I've used 3–4 times they are awesome.
