Tubes Lets Talk Flat Tire Fixin"

Discussion in 'Bicycle Repair' started by, Aug 6, 2010.

  1. I would like to see a discussion on what works and how to repair a flat tube. The junk I get at the high dollar fancy bike shop suck too. Bring back CAMEL hotpatch !

    To do no harm, to this thread

    Hey Will,
    To support not take over your thread.

    I'd like to know this too !!
    I have about 10 punctured tubes, that could still be used.
    I now have time to repair them.
    Additional questions.

    I have four bikes.
    How do I accurately know which bike the tube match's ?
    So, I can sort the tubes out, and know which one to grab
    in an emergency.

    I think I'm going to practise changing tubes on a bike or two.
    So when it does happen when I'm on the road, I can do it in a snap.
    Also, there are bike videos out there on the web,
    that do explain fixing tubes. Prolly posted here somewhere...

    what you need is the good old "monkey glue and patch kit" that we used to use in the
    70's when i was a kid.

    first things first, you need to remove the tire from the rim using either a set of tire removal levers, or the ends of 2 crescent wrenches. never use a screwdriver or anything that might put more holes in the tube while you try to take the tire off the rim.
    In the "monkey glue and patch kit" you would get rubber patches of all sizes. the patches had a sticky side covered with plastic that you had to remove prior to use, and a non sticky side. some rubber cement that was VERY flammable and a metal "cheese grater" type inner tube buffing tool.(this was actually the lid of the can, and the can was made of thick cardboard.)
    once you have the tube out, fill it with air and stick it in a bucket of water. this will help you find the hole(s) a lot easier.
    first you scratch up the area on the tube where the hole is with the "cheese grater" type buffer. this creates "teeth" in the rubber innertube for the cement to adhere to.
    you smear some cement on the tube and let it tack up for a few minutes. remove the plastic on the patch and put the sticky side of the patch against the glue. put the tube on the ground and then roll the can that the patch kit came in over the patched area to get the patch nice & flat. this also helps squeeze out the excess cement. then you light it on fire, which burns the excess glue off, and heats up the glue under the patch and permanently bonds the inner tube rubber with the rubber cement.
    seriously, this is how we did it back then and this is exactly what the instructions told you to do. it worked every time and we rarely got a hole or leak in the same area after we did this patching method.
    when you put the tube back into the tire, make sure that the tire is half mounted ot the rim (one bead on the rim, one bead off the rim so you have a void between the tire and rim to stuff the tube back into the tire. first, put the valve core in the tire and line it up with the valve core hole in the rim...then put the valve cap on it. this will keep the valve core from pulling back up into the tire while you stuff the rest of the tube into the tire.
    get the entire tube into the tire and remount the tire to the rim. 9 times out of 10, you can re-mount the tire to the rim without any tools...just use your hands to pry the tire over the rim. use a little bit of soapy water, spit, or glass cleaner on the rim. this will help get the last 2-3 inches of tire onto the rim a lot easier.
    if the valve copre ends up crooked in the hole int he rim, now is the time to straighen it out. grab the valve core with your fingers, and rotate the tire keeping the valve core still. rotating the tire will turn the tube inside the rim so you can get the valve core straight.
    when you fill the tire with air, squeeze the tire with your fingers above the valve core while you hook up the pumpand while you pump air into the tire. this will prevent the valve core from being pushed up inside the rim.

    the problem is that you probably can not find the old type of rubber cemenet that came with these kits anymore because it is very toxic, flammable, and the fumes are poisonous when it is burning.
    i'm not sure if the "new" tire patch glue will even burn, but if it will, i would try this method with it and see what happens.

    which bike the tube matches?????
    a 26" tube will fit in any 26" rim (except for 10 speed, and road bike type tubes which are very skinny). if you have a 26" mountain bike tire & wheel, any 26" tube will fit.
    if you have a 24" mountain bike tire & wheel, any 24" tube will fit.
    10 speed and road bike tubes are very easy to identify because they are very skinny compaired to mountian bike tubes.
    if you are unsure if the tube is 24" or 26", just lay the tire on the ground without the rim on it, and try to put the tube inside the tire. if it fits and fills up the cavety in the tire, then it's the right tube, if it won't fit and does not fill up the cavety, then it's the wrong tube.
    i am not following what you are saying about putting the tubes on the bikes that they match.

    Lil shortcut that has worked for me.......If the puncture is obvious (nail sticking out of the tire etc) I just break one bead with the tire on the bike. Then pull the punctured portion of the tube out and patch it. Have a cigarette (or vice of your choice) and stuff it back in. Do all the centering etc hints from above and reinflate the tire. Then go ride.

    This saves a lot of grief for me on the bikes that have a drive system that make it a bear to remove the back wheel. Also, to add to the patch adhesion I sometimes use that pair of pliers in the tool kit to squeeze the patch to the tube. Works well for me.

    Yesterday I got my first flat this year, so I get it home and I thought I would try the slime stuff. Well it leaked out as fast as if I did nothing to it, the green stuff lined the inside of the tire a little. So the flats they seal up have to be really small I guess. This hole was pretty quick to get the tire flat in 5-10 seconds after pumping it up.

    Most of these young whippersnappers have NEVER used a "HOT" patch, much less seen one...Thanks for the memory..

    Well buy the Camel patch kit......This is but one supplier of good patches.. Maintenance-_-Automotive Exterior-_-1EKW4

  10. I prefer to stop the problem at it's source by either using tire liners or kevlar tires. They have always been well worth the investment.

    Agreed, I also use tyre liners but still carry a spare tube and repair kit.

    I like to be prepared as much as possible.
    1: Tools required to remove wheel and remove tire and tube from wheel
    2: Tuffy Tire liners
    3: Spare tube, Rema patch kit in case of a second flat.
    4: Also carry something to boot a large hole in a tire. I use a piece of levis material soaked in contact cement.
    5: Read the linked article by Sheldon Brown and remember because of the higher average speeds traveled by motorized bicycles you are more prone to flats from a pinched tire. Meaning the tire is forced down to the rim.

    Super tubes! Good quality tire levers. (the kind that come in 3 and stack are nice). And tire slime. Auto parts stores sell vulcanizing patch kits for cheap. Rubber cement also can be had in little glass jars from craft stores, including a swab attached to the lid.

    There are some BMX jumping tubes that are very thick and come in one straight piece that can be looped, so you don't even have to remove the axle.

    I was trying to figure out what a leviss was, but I think you mean a denim patch, like you put on the knees of blown out jeans. haha

    Yes I do mean denum. The slime is a no go for me. It is great with things like cactus burs and thorns. If you get a larger hole the slime will poor out and not clog the hole. At this point you better have another tube.

    I've cut a chunk from an empty water bottle to make a boot, and it got me home. A piece of denim should work, as would a piece of scrap pool drain hose (PVC/vinyl, 2 inch hose, flexible...)

    You can also use a long piece (82+ inches) of pool drain hose as a very tough tire liner
