So I'm half way on my commute this morning, cruising at 75 MPH on the freeway when my low pressure warning pops up. We've all seen it before and it's usually complaining about 1psi or something stupid. But this morning all the other tires showed 44 psi and I right rear showed 37. So I watched it. It dropped to 36 within a couple minutes. Hmmmm. Then it dropped another psi within another couple minutes. So, wow, this wasn't a slow leak. I immediately got on the map to find a close tire store. Another psi. Found one about 5 miles away and got off the freeway. Another psi. I watched it slowly drop as I made my way to the the store. At around 25 psi or so the message changed and recommended that I pull over immediately. I was close and just kept going. Finally arrived to a closed (it was 7:30am) shop with about 25 psi. Got out and looked at it. Didn't look flat, but was low. Leaned down to look and I could hear the air leaking! Used my finger and found the hole. They arrived at 8 am and patched it up. They didn't have hockey pucks, but there jack saddle was small and he was careful. $15 later, all is well. I really loved having warning that let me know to get off the freeway! I will put my pucks in the trunk for next time. The experience could have been WAY WORSE!
