I find it easy to properly torque the wheel nuts by myself - if I use the right accessory tool.

I made this out of 3/4" plywood. Just choose the slot that is closest to the nut you are working to support the extension close to the torque wrench. Works extremely well.

That is a great tool!  Probably a lot more steady than trying to hold extension in place by hand.  You need to apply for patent & sell this to large truck tire shops everywhere.  Don't forget us when you are rolling in cash! Let us know when you hit "Shark Tank" with it!
