Hi everyone. Like another member in the forum I bought my metris used and one year later (today) I have a flat tire. Guess what.. no tool kit just the jack. Can anyone tell me what is the size of the tool that lower the spare tire? I know its an hexa but have no clue what size. I have everything needed to replace the tire but I can't lower the spare. I'm glad it happened near my home. Any help is really appreciated. Thank you.
