About this deal

The kit, which handily rolls up into itself and secures via a double-sided Velcro strap, is tiny and light enough to easily join your existing flotilla of tyre-fixing accoutrements. It does this by spreading the relatively high pressure of the cycle tyre inner tube over a larger area than the area which as been damaged. To do this, it must be positioned inside the tyre. While something outside may help by keeping water out and perhaps protecting the cut area from the road surface, it will have no effect whatsoever on the problems caused by the cut. To use, just pop inside your tyre between the inner tube and carcass. The pressure of the inner tube should hold it in place although you can always carry a tube of SupaGlue if you want to be sure. But things do go wrong and, with that in mind, there are a few things that you should know how to fix on a bike, especially if you’re thinking of going off on a big ride for four or five hours. Sure, some things can only be fixed in the workshop, with the right tools, but there are a few things which can happen out on the road which you should be able to rustle up a fix for to get you home. Being stranded miles from home with a problem you don’t know how to fix is one of the worst feelings in the world, even more so if you happen to have no phone signal as well.

One of the beauties of the bicycle is its simplicity. Unlike a car with its multitude of expensive, inaccessibly difficult to source or fit parts, the bike has very few pieces, all of which can be repaired from the comfort of your own home (or most likely garage, if you don’t want to get thrown out by your other half). Add the tubeless tyre patch and press down firmly. Try to avoid touching the surface that is to be glued because this can contaminate the adhesive. Anyway, first, cut both ends off the toothpaste tube. I’m using Aquafresh Extreme Clean, figuring the word ‘extreme’ in the title lends a suitably rugged air to my tyre boot. The reason for the name is that it is designed to save space and reduce weight compared to a full-size replacement wheel. However, although they are a great option, they have narrower and shallower tread depth than regular tyres and this means they are designedto get your vehicle to a garage in the event of a tyre failure. Space saver wheels also have a lower speed limit, which it typically below 50mph. Since it's usually a roadside problem then the overriding feature is that it has to be available, either being carried by the rider or obtainable nearby.

If successful, a patched tubeless tyre can last for many rides, often to the end of the tyre’s life. How to repair serious tyre tears It follows from this that the boot must be inelastic - or slightly elastic such as a piece cut from another tyre. Do not buy a spare wheel and leave it unsecured in the boot of your car - it maydamage the car's interiorand could cause a seriousinjury to the vehicle's occupants in the event of a sudden stop or accident. My guess is that there are many more times people could have used a boot than there are times when people actually have one. Depending on the patch type, these may need minutes or hours to dry, before setting the tyre up tubeless as normal.

How often something is useful is a question that is often answered with a percentage. For example (making up numbers), Split bars version can fit snugly in the boot of an MX-5 when not in use. Thanks to special split bar design and it’s easier to store in your garage and can be shipped to customers worldwide.

After that, its just a question of cleaning it up and stashing it in your Camelbak for when you need it. I was particularly pleased that I managed to complete my tyre boot without removing any of my fingers, as you can imagine. I know bike testers like to talk in terms of one finger braking but I’m not keen to put the theory into practice. Inflate the tyre to your desired pressure, taking additional caution with high-pressure road tyres, and rotate the wheel so that the plug is at the ground for a few minutes before you get going again. This will allow some sealant to flow into the repair and fully seal things. We’ve put together a guide to five different potential bike malfunctions, from repairing a punctured tube to fixing a broken chain, and how to overcome them with nothing but your own two hands, a bit of common sense and some very basic tools which you should have on your anyway. With the plug in the centre of the tool, insert it into the tyre, making sure you don’t push through fully. The added tubeless tyre patch should stop any air leaking out from the inside of the tyre.

As a general point, I think we can agree that the purpose of a tyre boot is to prevent or at least reduce the tendency of a tyre to bulge or even allow the inner tube to emerge and burst, when the threads of the tyre's carcass have been damaged by a bad cut. Boots are a pre-made item that can be plausibly sold, which is reason for them to be made and sold. Next, use your tubeless plug tool to make sure there’s a sufficiently large hole for the plug to enter – carefully insert the spike into the tyre to avoid damaging the rim tape, and twist to give a clean, round hole. As I've posted, I've been successful a couple of times with improvisation, but the Park Tool boot was disappointing. Others have had better results. My experience is that tire boots genuinely help with sidewall failures. I have had two failed sidewalls, the first was remedied with a homemade tire boot based on Velox cotton high-pressure rim strip on two sides of low-pressure plastic tire strip, and the second was remedied with Park Tool TB-2. In both cases, riding without a boot would not have been an option, and the tire boots helped enough to be able to temporarily use the bike (but since it's not a permanent repair, the outer tire needs to be replaced as soon as you can reach a shop that sells new tires).Thread a tubeless plug through the head of the tubeless plug tool. Most tools will come with a choice of different plug sizes to suit the size of the hole. Then twist carefully to slowly remove the tool, leaving the two ends of the plug on the outside of the tyre. First, you’ll need to roughen the surface that you want your patch to adhere to, using a little sandpaper, making sure there’s no debris left from the puncture. Cleanliness is key when it comes to gluing patches. The philosophy of a "boot" being wide (or long) enough to span the full width of the inside of the tyre and beyond is that trapping it between rim and tyre on both sides gives additional fix and augments the strength of the adhesive. This was the method with the old (traditional) rubberised canvas patch, which often became semi-permanent if the gashed tyre was fairly new.

A tire boot is actually useful as often as someone has a cut, scrape or tear in their tire that can be repaired by the boot. Using stitches perpendicular to the direction of the slash can help hold the casing of the tyre together before you insert an inner tube. Space saver spare wheels are designed to be used in the event of a flat tyre or other emergency situations. They are not meant to be driven on for extended distances or at high speeds. So if I'm going far from home, I tend to carry a tyre. Boots are supposed to be get-you-home repairs, and that can be a long way: it's not unknown for me to be 150km from home riding through the night with the shops shut. Given that, about the only good thing to be said for boots is that they're small and cheap. If you don’t have a boot but you do happen to have tooth floss and a needle, you can actually sew up a torn tubeless tyre.If you do use this method, it’s a good idea to add something between the sewn rubber and inner tube, such as a strip of strong tape. Getting the actual data to assign a percentage of the time a boot is useful is impossible because no one collects that data. The anecdata I've collected fits with my own experience - when you need them, they don't normally help much. For more stubborn tubeless tyre punctures that can’t be fixed with a plug, it may be necessary to patch the tyre internally. The process for this is very similar to patching an inner tube.
