I know I should have put this with "Tires" but it would be buried somewhere in the thread and other readers would get bored before they got to it. Anyway, I read that a torque wrench is necessary at Driver's Schools to insure the wheel lugs don't come off in the middle of a session. Can anybody give me direction as to what type of tourque wrench would be both reliable and inexpensive? While we're at it, would a small portable air pump that draws power from the oulets in the car be feasible for the schools? By the way, it's 5 degrees in Northeast Ohio, which I assume is extremely balmy for those from Minn., while its 40 degrees in Alaska, there is something seriously wrong here. On the upside, we're getting closer to April.
