Any idea's on how to get this one off? Discount tires? Goodyear? call my road side assistance maybe?|||Your going to have to get a "nut cracker" from a parts store. Splitting the nut is the only way to get it off.|||Find a 1/2 drive socket, and breaker bar with long handle, find socket size that would almost fit over the lock lug nut, take a good heavy hammer and hit the top of the breaker bar forcing the socket to be pounded on to the lock nut. Maybe add a piece of pipe called a cheater pipe for extra leverage, slide over the handle of the breaker bar. (plumbing pipe) for cheater, leverage......|||Tire stores have a special tool that they POUND onto your lug nut and then use it to turn it off. They use it for specialy keyed lug nuts (sounds like that is what you actualy have) that are installed as anti theft. If they are "star" then they could be a big Torx.... Go to your local good auto parts store and ask them to help you get the right tool .





Or if they are specialy keyed ones then get them removed at a tire shop and replace them with ones you DO have the proper key/tools for.|||Take it to a welder. They can weld a bolt on it.
