Borgschulze said:I replace tubes, they're usually cheaper than buying a patch kit.
A patch works out at about 30p. A tube is typically about 4 quid (less
if you buy in bulk). I guess I typically patch a tube about 8 times
(sometimes a lot more, sometimes a lot less) before discarding it. So,
that's £2.40 worth of patches instead of £64 worth of tubes. Given
that I've had periods where I've had that many punctures in 2 or 3
months, I've saved a fair bit of money by patching.
That's on a bike, though, which has been my primary mode of transport
for most of the last 16 years. I think I've only ever had one puncture
in 13 years of unicycling, and that was a few weeks ago from the rubber
perishing at the base of the valve stem. Obviously not patchable. If
you puncture so infrequently that the tube is starting to perish
anyway, then patching doesn't seem so economical.
One other benefit of patches is that they're so easy to carry. I
always carry two spare inner tubes on my bike (my wheels are different
sizes). So, if I have one puncture, I can change the tube. If I had a
second puncture in the same tyre on the same journey (which has
happened on occasion) then I'd be stuffed without my puncture repair
kit.
