Hope this hasn't been asked before, but here goes.
I have stopped using Mr Tuffy's because at least half of my flats have been caused by Mr Tuffy himself!
This is because at high inflation the blunt end of Mr T. wears a hole in my softer tube. Those of you who have used him will know the result!
So how do you shape the end so it is smooooooooth? 'cause he just resists being manipulated and shaped. (even tried wringing the little blighter's neck!)
Thanks for the replies, sillystorm
