Default Cup 2 tire ran for a while with 14 psi

So apparently my TPMS came loose and allowed air to leak out. Pulling the car into my garage, my son said, "You have a flat". I stopped the car and noticed that the tire was super low at 14psi. TPMS coded out but will be turned back on as soon as I can figure out how to do it. Now the sidewall looks as if it did some time on the pavement. I have no idea how long I was driving on the semi flat but it's maybe 30 miles.

Here are the questions I 'm wondering about:

1. Would you replace the tire? I will check the inside on Saturday but just trying to get a feel for what's the best thing to do.

2. Would you hold the tire installer at fault and make them warranty the tire? Remember this tire is brand new, driven maybe a little over 240 miles. I went in today and spoke with them about getting the tire replaced and well, I'm hoping they do the right thing.

3. Would you just tighten the TPMS and refill the tire and go about your life.

Thanks for any insight and opinions. Oh, it's a Cup 2 tire and the car only gets driven through the canyons for the time being, albeit at a decent rate of speed.

I’d replace. I expect the structural integrity of the tire is stuffed. Bummer. But better than lapping waiting for it to blow…..

you'll know,... you'll get your answer once you take the tire off & inspect the inside turn radius (where sidewall meets backside of tread)

Front or rear tire? Front tires don’t have that much load on them.

i’ve come off the track with tires under 10 psi on two occasions. On both occasions fixed the cause of the leak and reused the same tire on track. No issues and this was racing. Granted Hoosiers and different tire but I honestly wouldn’t fret much about it. If you can get a new tire from the installer fine. 14 psi when you measured it, prob 16-20 psi through most of the drive, not an issue I don’t think.

Correct it was the front tire and I’ll keep you guys posted as I’m having it dismounted tomorrow morning

Ahhh, I also thought it was a rear.

even more so now you should be in good shape.

Btw, I've had instances where I took a nail in a tire while out on a cruise,.. and had to keep filing it up on the way home (& recall times where it was down below 20 lbs). The tire was perfect on the inside. Patch it up & used it for another 3 yrs till the tread ran out.

I'd replace it. A tire driven at low pressure builds a ton of heat. Why risk it? These cars are getting expensive. Blowouts can take fenders with them.

Yes I'd hold the tire installer at fault. People make mistakes, and there's nothing you could have done through normal use to cause the TPMS to loosen up and leak.

Plus, they're new, so you don't have to concern yourself with uneven tread depths like you might if you have to replace one corner later.

Plus all the tires look real nice and that front tire, well, it's a little wounded. LOL
