Even if that's true, by the time you've got through the contents of that box, you've saved a dozen tubes from landfill. That has to make sense.As set of patches and the little box they are sold and displayed in probably takes as much to make and distribute as a new inner tube.
But why?I throw the inner tube away when it gets a puncture!
Never patch tubes always use newI've got a puncture on my 'new' eBay bike.
On removing the tyre I found an inner tube with no less than seven patches already. Soon to be eight because I don't have another to hand - but this got me wondering how many patches you use before you consider a tube finished?
I think this will be the last one for this tube; I'll be picking up a spare tomorrow!
Because I have better things to do with my time.But why?
