I had a flat last week. Today I just went and got the spare fixed, so I'll be ready for the next flat. I get about two flats a year. That seems high compared to most people I know. The reason I have so many is that most of then come from driving my pickup to the landfill where there are always plenty of sharp things burried in the gravel to puncture a tire. It has never been a sudden blow out; always a slow leak. The day after I go to the landfill, I find a tire has deflated. How many flats do you get a year?
