Bummer, were you able to make it home, patch kit time.
Oh yes. I can't tell you how much I LOVE these TPS sensors. It is the second time they not only warned me I had a flat, but also their readings told me it was a slow leak flat, and I could get home as I monitored the pressure in the highway.
First time was a couple of years back, when I was about to leave from work and the front tire was on the ground. I inflated it, and rode to the shop while monitoring the pressure on the dash.
This time yesterday, as soon as I got on the freeway, I noticed the rear pressure was at 35psi, compared to 41psi that same morning. I immediatelly knew I had an issue. And at the same time, I knew I was OK to keep going, as I had enough pressure (35psi), and I could keep monitoring the pressure as I went.
These sensors are one of my favorite features of this bike. In addition to identifying a possible flat, they also let you know when you tires are warm in cold mornings after a few miles, when the pressure goes up a bit.
But again, I have zero experience with patching, or having it patched, or riding with a patched tire. If I fix it, can I actually ride the remaining life of the tire on the fix? If not, I would just patch to learn how to do it, and then get a new tire anyway. The bike is in my garage.
