I'm not sure if this is the right forum to post this question but I'll go for it anyway. A portion of my route (haven't ridden it yet, hope to start this Friday) is through a nice quite residential neighborhood. Problem is the streets are asphalt with large gravel in it. I don't know what it's called. The gravel is not loose, it's actually embedded in the asphalt. Anyway...the ride is bumpy but I'm more concerned about the effects on my tires. I have a roadbike so have thin, slick tires. Is this type of terrain more conducive to getting flats? I hope not. The neighborhood is a safe alternative to a much busier and narrow road.
