Yea, I like to think my 3 spare tubes will last me forever since I don't see any limit to patching a tube. The only way I'll throw on another tube is if I'm running low on patches in my kit and want to conserve them. I'd save the busted one to fix later.
However, I used to have one or two tubes a year bust at the valve. I wasn't doing anything wrong as far as I could tell, but that just stopped.
That way I don't have to f*** around with rubber cement
It's not rubber cement. I'm not trying to make a point by correcting you. I'm just correcting you.
