Hello every one. So I had a flat tire earlier this evening. After I put on some gas I was still able to drive probably around 4-5 miles and during the middle of the drive I was already feeling something's off on my side but at first I thought I just had something stuck underneath because of the vibration and sound. My TPMS never warned me of low tire pressure. It didn't go flat right away as I was able to drive a couple of miles crossing one city to another. So my question is, shouldn't TPMS be lighting up though during the drive once pressure started going low? If I'm not mistaken it should light up once it's lower than 25% of normal PSI. I'm taking it to my dealership tomorrow but just wanted some input. Thanks guys. By the way I have a 2017 civic hatchback ex. What's funny is my TPMS lighted up right away when spare tire was put on but never lit up during the whole flat tire process.
