my daughter has a 2012 elantra limited that has a shredded tire, I had it towed to my house and went to remove the tire and it has a security key type bolt. Of course she lost the key so I watched videos on how to remove them with a diamond socket but I cant find one that fits.

I tried 15/16 - too small
7/8 - too big
21mm too small
22mm too big

Im not sure what to try next seems like its in between sizes.

 

Hi Sam,
You might have better luck if you went to an auto supply store like NAPA or Advance. There are others , but I don't know if the discount places sell this type tool.

 

Sometimes we have to make a sacrifice
Take the smaller one and hammer it onto the nut or bolt
Hopefully it won't split the socket and it will take off the offending component
Afterward, don't think too much about trying to get back or reuse the socket.
