Well it's official!

I have a spare, jack and all that. I checked the tire when the light came on it wasn't very low. I was coming into town and Discount was the closest. Also bought the tires there. This is in my 2002 mini van. I filled it up last night and came home. Just went out and pulled the tire and it is still full. I'll drop it off this morning. Discount does not charge for flat repair even if you didn't buy the tire there and they do patch on the inside, not just cram a plug in there.
They said that not knowing if the tire has been ran flat is the reason for the 15lb limit.
It's a candyass world we live in now days.
