While entertaining a crew visiting from Bike Freak Magazine, the Chinook Cycling Club took them on various rides and introduced them to the famous tackweed (goathead) and a site dedicated to eradicating it. That reminded me of all the tackweed flats, running Slime, Mr. Tuffy’s, and it was usually better to leave a goathead in the tire until you got home.
In Seattle, most flats are caused by pinches, glass, staples, nails, and it’s much worse in the rainy season. Starting last year, I stopped using Mr. Tuffy, and instead roll the best tires with the most rubber and replace them as soon as they wear. I carry two tubes, and a tire boot for sidewall blow outs. I’ve also got fast patches and regular old Rema Tip Tops.
