I'll sidestep the plug/no plug angle here as mentioned. Personal choice I make when I need to make it.
You'll have to make up your mind on risk vs. reward...we all have and do what we need to do.
Discussed recently in Just Ridin':
I will add that sometimes it is where you ride that gets one to this point. I speak from my own personal encounters of the hissing tire.
Are you riding in a known construction area, on the shoulder at times to look at map or chat, turning thru that triangle of debris at a lot of intersections or riding in the center of your travel lane? All these factor in picking up debris.
I have a lot less flats now( knock-knock) that I do not commute into the ever present construction zone of Austin,TX. You could see things fallng off of trailers and from pickups on a daily basis. My common flat maker was drywall screws.
