Donald I went out and bought a nice new torque wrench just for the job. I will buy a nice good socket for it which wont break on a frozen lug... Mine has 17mm lugs - Aftermarket Wheels.
I had the 4 point lug wrench, it did not come with the car, its basically one of those crowbars with 4 sockets on it in various sizes. Only this one was foldable, and really did not have enough size to generate good torque to remove the wrench. It ended up actually twisting the chrome vanadium bar.
What I really need to do is get a good socket and a piece of metal tubing to extend the handle of the torque wrench for added power to undo the bolts, but I did not get that far since the socket broke which means I had enough torque on that puppy.
I plan on taking it in to the tire shop tomorrow to have them impact that lug off. I will then probably just buy a couple of new lugs. and have them loosena nd hand torque each lug. Then drive home, take off the wheels and do what I wanted to do today.
