Park Tool TB-2 Emergency Tire Boot (Pack of 3)

have used these on a pretty torn up tire to get home--good addition to an under-seat bag or keep on with a spare tube. self-stick, functional, don't take up much space, and might get you home if the tire takes damage instead of just the tube.

I purchased these well over 2 years ago and carry one in my repair kit along with some cash and bandaids. I ran over glass that sliced my road bike tire and tube. Continental GP 5000 with 90/lbs of air pressure. I pressed the patch in place, pumped the new tube and so far ( fingers crossed) it works. I've put another 60 miles in since the repair a few days ago. All seems good. Eventually, I'll get a new tire and move the damaged one to my winter trainer. The patch works. Highly suggested.

I have used the tire boot a number of times to fix tread areas, in particular for nail punctures. However the best usage was when I came across a biker who's sidewall had failed. There was a big gash in the sidewall at the rim, about an inch, caused by her riding with a flat tire. She had a spare tube. I applied the tire boot, but given the length of the slit and that it was at the side wall, I figured the pressure from pumping the tire would apply a tensile force on the patch and cause it to slip, and fail. So I added two large tie straps I had around the tire and rim, to give it some hoop strength. She then successfully rode back to the nearest bike shop about 4 miles away.

Be aware that these patches are for inside your tires, not the outer surface of your tubes, in situations where you can actually see the tube through a hole in the tire. If you're looking for glueless / pre-glued patches for your tubes, I recommend Park Tool brand for that as well though several other brands also make good pre-glued patches. These patches are a great solution even in the worst of cases where the tire has such a large gash in it that there would otherwise be no way to inflate the tire without the tube bubbling out of the cut and exploding. The patches themselves are tough enough to hold up to debris (even glass) getting in the cut, and there is effectively no expansion out of the tire--whereas the old solution of using a dollar bill isn't nearly as good or durable. They are rather thick--at least as thick as a tire sidewall--yet using one doesn't leave a big bump the way many glue-on tube patches do. SIZE: I thought I would buy these three patches and try them out and then buy more immediately if they did, but each of the three is so large that you can cut several patches out of them--as suggested on the packaging. In fact, one whole patch is actually too big for a road tire, and really wouldn't be necessary in a mountain bike tire--unless it was a big three incher and the cut was reeeeeeeally bad. CON: The only source of disappointment with this product is that the glue is only about as adhesive as that of a Post-it Note, perhaps not even that strong. The glue doesn't even hold the patch in place while you're installing the tube. However, the solution is not to glue it in place; just slip it in between the tube and the tire when you have the tube partially inflated and installed, then put the tire back on the rim and inflate to normal pressure. Note that I haven't tried this on a mountain bike tire with low pressure yet, but have never personally had a mountain bike tire (2 inches in width or greater) with a hole that big in it. BOTTOM LINE: Some riders pay $50 or more per tire, and when one gets a gash in it, even if the tire is brand new, that usually means putting it in the trash right away and spending another $50 or more. That's exactly what happened to me, but I didn't throw away the first tire thank goodness before buying these patches. My replacement tire also got rather cut up over time to the point that I actually had to patch the tire itself in a couple of places. But with these patches I was able to reinstall the first tire which was otherwise completely new. And though I can actually see the patch through the gash in the road tire, it doesn't bubble out and I'm completely confident I could ride it like that for the remaining life of the tire. I now carry one of these patches with me on every ride--just in case.

Works fine when you need it.

Sticks to the inside of the tire very well makes a good temporary repair saved a lot of hassle in the field one day

saved me from a long walk back to the car.

I got a large sidewall slash from a piece of sharp metal on the road. The hole is big enough to put my finger through. This Park Tool Tire Boot has solved this problem. It easily stuck to the inside of the tire and is strong enough to hold in the tube even at 60 psi. It has held up for a week of daily driving while the new tire was delivered. It shows no sign of failure so I'll be keeping the patched (booted) tire as a backup just in case. The Park Tool TB-2 comes with 3 boots, so I still have 2 left. An excellent product.

Seems like all are old stock. The glue does not stick at all , even after cleaning tire surface with isopropyl and applying there is no stickiness to the glue. probably glue has lost its strength. should not be selling these. please remove from amazon. complete waste of money and time. DONT BUY

Nous avons fendu le pneu et nous avons roulé sur 550 kilomètre sans changer le pneu c’était parfait.

2 sorties après l'achat déchirure du flan et l'équipement m'a permis de rentrer avec la chambre à air

Die Kassette hatte ich damit problemlos abbekommen, ohne weiteres Werkzeug verwenden zu müssen.
