Webster's defines "skill" as: 1) The ability to use one's knowledge effectively and readily in execution or performance; 2) Dexterity or coordination, especially in the execution of learned physical tasks; and 3) A learned power of doing something competently. When we think of the skilled trades, what commonly comes to mind are those of the carpenter or the woodcrafter, the jeweler or the diamond cutter, the pipe fitter or the plumber, or something along those lines. It is reasonable to ask, then, whether the proper servicing of commercial tires is considered a skilled trade.
