Don't obsess about flats. My experience has been that no matter what I do, sometimes I have more than at other times. This past year, for example, I had a single puncture during the whole road riding season. I always carry a couple of spare inner tubes, along with a pump and tools needed for flat repair. As noted before, I only needed them for myself once, although my pump was used several times by others on group rides. Your stock tires are fine. Even puncture resistant tires are vulnerable to pinch flats no matter what you do. . One thing that I do not do is to ride until my tires are paper thin. At that point almost anything can puncture your tires. The best possible way to protect yourself is to be able to effect a repair on the road, by having the needed supplies and ability to quickly get going again. You will have lifted a cloud from above your head and you will be able to ride without worrying about your tires
