Last Friday I had a nail removed from my tire. It's the fifth one in the last 12 months. I think that's an excessive amount of nails. I cannot figure out why there are so many nails on the roads. It's not like they have roofing on our highways. Yet the nail problem persists. This one was in the sidewall of my tire and couldn't be fixed. Fortunately I had road hazard protection and got a new tire.
