That list of spares is what I bring on most tours, even in USA. Pacific Coast, I left my spare tire home since I assumed that route would have enough bike tourists that all bike shops would have a useable tire. But my other tours included a spare tire, especially when I was using a reasonably narrow 26X1.5 (559X40) tire which most stores do not stock.
