Another way I've had success with, is to use a torch and heat up the lug nut. It will expand and be easier to remove.Car tire change?Get a mechanic to do it and shoot the last person who changed your last flat.Car tire change?They make special sockets that grip onto stripped nuts and bolts. The socket works by you hammering it on, then use a standard Johnson Bar to take off the nut. Most auto supply and tool stores would carry this... or you can buy Snap-On tools (expensive option).
Option B: Cut or Break it off. You will then have to replace the Stud and Nut. With a basic mechanical back ground... Studs are easy to change.
Note: Vise Grip solution is a waste of time. You will be unable to get the Grip or Leverage on a Vise Grip to remove a nut this size that is seized.Car tire change?A very sharp (or brand new) chisel and hammer. Place chisel along the bolt going toward the drum or disk brake and do not hit recklessly. This will damage the bolt but it can be replaced.Car tire change?There is a socket you can buy that fits on a 1/2 inch rachet that will bite a rounded off bolt or nut. Can't remember the name of it but they work. A friend has one and it works!!!
Go to an auto parts store, buy the socket and a replacemen nut and have at it.Car tire change?You can buy a special tool just for this problem from a professional tool dealer like Snap On or Matco, or take it to a shop. Either way it will end up costing you a fair amount of money. You could try to beat the next smaller size socket on, but usually it does not work.Car tire change?Vice grips and maybe a squirt of Liquid Wrench. Just be careful to get all the Liquid Wrench off the threads before you put the lug back on again.
