    Cutting a FREE "steel belted radial bicycle tire liner" from used car tires.

    I am attaching a lot of images of what automobile tire manufacturers have generally settled on after over a century of extensive research. Sure, one could use Mr. Tuffy liners, old bicycle tires, old tubes, slime and tubeless setups, but since we all have motors we can integrate the weight of this automobile tire technology into our ebikes and surely get less flats.

    Implementing this idea is as easy as:

    (1) obtaining a used street tire larger than your bicycle tire from your friendly neighborhood tire store,
    (2) measuring a 1-4" strip around the middle of the used tire,
    (3) cut your hoop with a drywall saw, sawzall, cutoff wheel, hacksaw, woodsaw, utility knife, steak knife, etc.
    (4) cut the resulting hoop so that it becomes a strip, not a hoop. This cut is perpendicular to the circumference. It needs to expand outward when you inflate the tire. Make it too short and you have an unprotected segment. Make it too long and it will protrude into where your tube goes,
    (5) To protect your tube from the "steel belted radial bicycle tire liner", put a Mr. Tuffy tire liner in between your tube and the new, thick tire liner. The Mr. Tuffy tire liners have one smooth, velvety side to keep your tube happy; the other side of a Mr. Tuffy tire liner has ridges to keep it centered.

    I am waiting until I get another flat to try both tubeless and this, but of course now that I want to get a flat I am not getting one.

    Ya gotta think that those steel belts would help!

    Just go buy a couple of these. I seriously doubt any normal cause for flats has much of a chance here. Plus, they really ride smooth.

      This tire makes for another interesting cutaway view, but they don't make it in my fat tire size.

        Yeah, I wasn't thinking fat tire, just highly indestructible. That blue part keeps anything under 1/2" from puncturing the tube, which to me makes the tire more than adequate for my needs as a touring bike user. It will get stuck in beach sand, so if you are looking for good floatation, this isn't the right tire. It does do hard surface, even rocky ones well though.

      Ever try cutting up a steel belted tire? Good luck! If you find an easy way, let me know. I tried once, and gave up.
      Fabrication is fun! Build something today. Show someone. Let them help. Inspire and share. Spread the desire.

        The steel belt wires have given me a flat tire.

        I don't think this is going to be helpful.

          Instead of spending all this time and effort trying to solve this continual flat problem, relace your hub motor to real moped/ motorcycle rims. The selection of tires available in the 16"-21" size is pretty impressive and much less expensive than bicycle tires.

            This guy did it in order to make treads for a robot: http://bobgreiner.tripod.com/id166.htm

            He cut it with a fine tooth metal cutting blade in the jigsaw and then sanded the edges down with a belt sander.

              Ahhh, with a board backing it up. OK, then, I'll remember that. Thanks!

                My frame builder (Design Logic) builds each frame around a specific tire size (for the rear, of course), and all four of my frames were built for tires from 4.80-5.05" wide and 30.5-31.5" in diameter. Before I bought frames from him, I had no idea that any frame builders did this.

                      That was easy, but no pricing...

                    I bought a used 170mm dropout frame 2 years ago for $495 plus shipping. It was red, so I powder coated it.
                    I bought a new 170mm dropout frame for $850 plus shipping. It was bare.
                    I bought two new 190mm dropout frames made to my specifications for about $1,540 each plus shipping. They were bare.
                    The frame builder has been welding steel frames for 35 years. His work is highly recommended.

                      You go to a lot of effort to avoid flats and yet fail. Meanwhile I haven't had a flat in 1200 miles on my bike with commuting tires. (knock on wood!!!!) :D

                      As I posted in your other thread, you want commuting tires like these:
                      Origin8 Supercell Folding Bead Fat Bike Tires, 26 x 4.0", Black/Black: https://www.amazon.com/Origin8-Super...+bike+puncture

                      Get the low TPI version of the tire.
