well i had a bad time yesterday changing mine.
as before i jack up the car get under and "usually"it twists with a little give.
not this time!
i found taking off the drivers side wheel gave me better angles to it.
in the end i tried tapping it up a bit,then it punctured aahh!
i got a loan of the clamp from a friend and it worked a dream.
i was two hours late for work.
lesson learned :xsmachbottom:
