How do I remove the valve core from a tyre? I have got a removal tool, but i don t know how to use it. I have tried to turn the valve core but the tool (plastic) cracked under the pressure i was applying. If it does have to be turned, is it clockwise or anti-clockwise? Do I have to let the air out of the tyre first? As the tool is now cracked, could i use a long nosed pliers or something similar?
Any help would be greatly appreciated.
