not patching your tubes is wasteful on a number of levels.
1) waste of money
2) waste of resources (where that tube going when you throw it out?)
3) waste of skills
on the commute, i replace the tube with a good one and patch the old one at home later. unless i also puncture that tube, that is.
it's good to keep the patching skills tuned-up -- you can carry a lot more patches than tubes.
i generally keep patching tubes until the valve fails or it gets a tear bigger than a patch.

Some people carry a spare tube on the road, and if they flat, they just swap in the spare tube, and then take the time back at home to patch the tube right, which after a good testing run, turns it into another 'spare tube' for the road. That way you don't have to sit by the road for long, but you still don't waste a perfectly good tube.

so if your repairs were altered you would have four tubes in seven years.. how does this equal the disposal of a car tire?
i rarely get flats when using quality kevlar tires, maybe every couple months... when i use cheap tires i get them weekly, so if we are to compare the environmental impacts of one that patches with cheap tires then i would speculate the impact could be much more compared to one that replaces a tube with each puncture given the rubber cement manufaturing and foil tube waste etc. that is entailed in the patching.
but really isn't this a hypercritical point?
i certainly don't think anyone is "crazy" for patching or replacing.. but then i replace so maybe i am indeed "crazy"

From an environmental stand point however, the amount of volatile organic compounds released by patching a tube rather than replacing it and the waste involved is far outweighed by volative organic compounds and waste involved in producing the tube even with multiple patches. A new tube requires lots more chemicals and energy to produce also as well as the solid waste from the packaging and the old tube. From that standpoint, it "better" to patch than replace...even with good tires.

Down south, in the desert, where the plants are pointy and evil, rode a lone biker in the second half of a double century, doom smote upon his tire repeatedly....... Well to make a long story short (too late), I had 14 flats one day. I can't carry 14 tubes with me but 14 patches is much more manageable. I had a kevlar tire bite it due to a road hazard and the spare tire was not kevlar. The rain had caused the road to become a bed of thorns. Anyway, I carry 2 tubes and a bunch of patches. I have never had a tightly lidded tube of glue dry up and that is after being stored in 110+ degree heat on a regular basis over 3 years now. I always close the tube as soon as I have applied the contents to the tube.
incidentally it irks me to no end having to pick up faster peoples tubes on the side of the road at organized rides. If you started with the weight you are certainly strong enought carry it back to the start.

a) if it's the right size, i just got a free tube (that i'll patch)
b) if it's not the right size, someone else will get a free tube (that i'll patch first).
c) if it's thrashed it's still usable for something.

I also use slime to prevent flats. I guess one could look at it like "an ounce of prevention is worth a pound of cure." Either that or the cost of patching a tire is about the same as sliming a tire. :shrug:

Let me understand, you have patch kits that the glue goes bad in??? I've been using the same tube of glue for 2 years....? It hasn't dried out and the tubes I've patched are holding just fine. Or at least the one I rode yesterday was. Patching is easy and works just fine.

I'd say how I patch tires but I've forgotten, it's been so long since I had a flat. If I got one I would patch it, though.
And back when I did get them, I patched them.

I won't put more than 7 patches on a tube. That's just where I draw the line. Patches are great but they add weight (each one insignificant amount but it adds up).

Another way is to "kiss the tube". Inflate the tube so that it is much larger then it would be in the tire. It should be half again as big. Then slowly run the tube across your lips like you are gently kissing it. It looks silly but we humans have lots of nerves in our lips which is why kissing is so pleasurable
If there is a flow of air you will feel it on your lips. Mark the place and patch it.Another easy way to find a leak is to find the object that caused it. If you have a big old goathead sticking into the tire. That's your leak! Don't pull it out! Take the tire apart find the object and fix the flat. This is the best way since you don't have to take anymore of the tire off the bead then needed to get that section of tube out.

We could have oil dripping from the chains of our bikes and replace tires and tubes everyday and still come out ahead in that department.

Count me in the patch crowd
Anyone who does not patch is welcome to send me their punctured tubes. I'll make sure they are carefully disposed of so they can pose no further danger to the original user
Cheers,
Ed

I'm one of those replace-and-patch-at-home types. I carry one spare and if I get another flat then I will do a roadside patch. However, I rarely get flats. OTOH, I am picky about my tubes and I'm a bit picky about paying too much for them too. I like a specific tube brand with a specific valvestem style and they're not always on sale. I pick up a couple when they are but as a result I'm encouraged to patch my old tubes and not just throw them away. I also give them away to friends. The only tubes I don't reuse are the ones which have had the valve pull out. I find other uses for that such as turning pieces of them into a plug for my seatpost in order to hold spare spokes...

patching tires is hardly a "skill"
i mean honestly it's pretty easy right? is there something i'm missing? FYI I replace but I could not imaging losing the "skills" to patch!
It is interesting however to notice that this question was aksed a few weeks ago on the road bike forum. The vast majority favored replacing vs. patching. Guess it goes to show that commuters are doing it for more monetary and environmental vs. physical and fun reasons. Not sure if my hypothesis works out but still it's interesting becuase there is a vast difference in the majority opinion between the two boards.
