anyone use a torque wrench to check the TT lugnuts? i've been checking the lugs before each road trip, but amazon just delivered me a nice torque wrench. wondering what setting i should use.
As nobby points out, many torque wrenches use a spring to set the torque value. A spring under constant tension can lose some of its spring force. This would make the wrench reading inaccurate.
By taking the tension off the spring between uses, we tension the spring only when necessary.
Change of spring tension over time, is one of the reasons many spring scales have a zero-set knob.
