DIY Puncture Proof Bicycle Tires

Bicycle tires with tire liners and/or thorn-resistant inner tubes are available to protect against broken glass and other road debris, but if you have access to old bicycle tires, brake cables and a measuring tape you can make an inexpensive DIY armour that will protect your tires.

Instructables user mariano states that cutting the bead off an older bicycle tire and fitting that bead inside your regular tires between the tire and the inner tube will protect you from 80 per cent of punctures, which is a cheap and easy solution. If that isn't good enough he recommends lining that cut off inner tire with the metal tape from a retractable tape measure.

The metal tape will act as an armoured barrier between your outer tire and the inner tube. The author recommends using the thin strand of wire from a bicycle brake cable to sew the measuring tape to the cut tire as using regular thread or dental floss will probably result in those materials being cut by the measuring tape. I'm curious to see how duct tape would hold up.

If you're looking to avoid bicycle tire punctures and Kevlar tires aren't in your budget you may want to consider this method. Any protection method you try will increase the weight and decrease the responsiveness of your bicycle somewhat. Note that the photo above is the tape on the cut bicycle tire that goes inside your actual bicycle tire.

    Typo above - they actually said to cut the bead off the old tyre and then put the *old tyre* inside the new one, not the bead off the tyre. The bead wouldn't do much, if you could force it in.

    I was also thinking not that long ago, I wish I put duct tape or find some other kind of strong metal type tape that could go inside the tyre when I was young. So many tiny bindi holes, after over 100 years of bike tyres, you would think by now they could have elevated this problem by now and probably have, just don't want to put it out their...

    But surely someone knows of a duct tape type solutions that has stronger properties and easier then getting an old measuring tape in your tyre... Maybe even a thin tin lining stuck down with duct tape would be better/easier option then repairing tyres every week or so. I know as an adult we keep to the tracks and roads, but when I was a kid not lawn was safe :)

    I've never had a puncture on the rolling surface, always the side wall.

    If you have access to old seatbelts. line the inside of you tire with those, they will go bald before getting a puncture
