I have the following torque wrench for a group buy @$85 dollars plus postage. The Trade price for this wrench is $165 dollars. Some things you show know when using a torque Wrench! 1. Once you have finished using it, you should set it the lowest scale reading to take the load off the internals parts. Plus store it in the blow mold case for protection. 2. Place your hand on the handle only as this does effect the torque reading. 3. Once the torque wrench clicks at the set reading, stop and release the pressure other wise you will over torque.
Last time I had new tyres fitted (to my daily-driver Mercedes rather than the TT, so steel rims) I was gobsmacked to see the fitter not only use a torque wrench, but also tighten the nuts in a cross sequence!! I think that's the only time in 30 years of buying car tyres
