Any motorcyclist who rides long enough will eventually have to contend with a flat tire out on the road or trail. It can be a time-consuming, ride-ending disaster with all the hassles and expenses of getting the disabled bike hauled to a shop for repair, or it can be a brief diversion that hands the rider an additional victory during their adventure\u2014even if that adventure is merely a quick trip to the store.<\/p>\n\n

Obviously, tire failures aren\u2019t all the same. Some are catastrophic, with a sudden blowout resulting in extensive, irreparable damage to the tire and dramatic loss of control over the motorcycle. Fortunately, these are rare and typically preventable with regular monitoring of each tire\u2019s condition and inflation. Otherwise, modern tires must be subjected to an extraordinary hazard to come to such an unsavory end. The more likely scenario for a flat is a simple puncture, with a nail, screw or other sharp debris piercing the tire\u2019s tread and allowing air to leak out slowly. Usually, the offending bit remains trapped in the hole it created and actually impedes the egress of precious pressurized gas. A rider may not even be aware there\u2019s a problem for long while after the damage is done.<\/p>\n\n

Maybe the bike begins to handle strangely. Maybe the tire starts to look deflated, or a nail head is visible amidst the tread blocks. Perhaps the bike\u2019s tire pressure monitoring system alerts the rider to a pressure loss. However the issue becomes apparent, this can be an easily remedied development requiring little in the way of special equipment and technical skill. A rider can rid their tire of the evil intruder, plug the hole, reinflate, and be on their way again in less than an hour. Keep in mind manufacturers advise against extended or extreme use of repaired tires, and plugs are usually effective only when a puncture has occurred in a tire\u2019s tread area, not its sidewall, and when that puncture is a straightforward, small-diameter piercing, as opposed to an oblong gash. On the other hand, there are cases wherein repaired tires have functioned flawlessly for thousands of miles without pampering, and creative riders (using multiple plugs) have managed to get a tire with a cut sidewall to hold air long enough to make it somewhere they can safely spoon on a replacement. You\u2019ll have to decide what risks are worthwhile in any given situation.<\/p>\n\n

In this two-part article, we\u2019ll look at a variety of tire repair kits in Part One and cover the basic procedures for using them. In Part Two<\/a>, we\u2019ll compare various options for refilling a tire that has lost air\u2014as a result of damage, temperature change or plain old entropy. We won\u2019t be covering inner tube patching, as that\u2019s a much more involved process affecting a dwindling number of motorcyclists (no disrespect, vintage riders!). In the current era, many ADV\/dual-sport motorcycles with wire-spoke wheels arrive from the factory with tubeless rim\/tire setups, and even pure off-road bikes can be converted to tubeless operation with Nuetech\u2019s ingenious TUbliss system (see tubliss.com), making trail-side repair quick and easy using the same approaches appropriate for street machinery. Hence, the tools and methods examined here have broad applications. The goal isn\u2019t to steer you toward any particular product, but rather to survey the types available with attention to their respective advantages and disadvantages.<\/p>\n\n

Tire Repair 101<\/h3>\n\n

Most tire repair kits work the same way. The fundamental process goes like this. First, the puncturing item must be removed if it\u2019s still present. This can almost always be accomplished with a pair of pliers (a needle-nosed version may be necessary if there\u2019s only a little still protruding from the tread). If it\u2019s impossible to pull the offending bit back out, it can instead be pushed the rest of the way into the tire\u2019s interior, where it will pose little realistic risk, though this is not ideal. Such pushing could be done using one of the narrow, cylindrical components of the repair tool. Tools generally include a rasp to roughen the puncture\u2019s interior and enhance the plug\u2019s adhesion, and a sort of \u201creverse needle,\u201d which carries the plug in an eye at its leading end. The latter is used to forcefully insert a string-like plug into the hole and then, because the eye is open at its tip, leave that plug in place when the tool is withdrawn. A slightly different design has no such opening and instead pulls the plug partially back out through the hole after first pushing it completely through.<\/p>\n\n

The Stop&Go kit uses a wildly different mechanism, as well as a different type of plug, than the rest of the kits shown. Its plugs are most worthy of that name, as they\u2019re little rubber mushrooms that fit the image of what most would consider a \u201cplug.\u201d More commonly, tire repair kits use sticky, fibrous, vulcanized, stringlike things that function as plugs. For simplicity\u2019s sake, these will also be referred to as \u201cplugs\u201d here.<\/p>\n\n

Once the plug has been inserted, whatever excess is left protruding from the tire\u2019s exterior is trimmed away so the plug can\u2019t be inadvertently pulled back out. A string-style plug\u2019s built-in (vulcanizing) adhesive permanently bonds it to the tire\u2019s rubber; air no longer has an escape route, and the tire can be reinflated with a reasonable expectation it will stay that way. String-style plugs come in a variety of widths. Thin ones can be inadequate for repairing larger punctures. In some cases, it may be possible to compensate for this by inserting more than one such plug into the hole. While this almost certainly decreases the trustworthiness of the repair, it may suffice to get bike and rider to a better location for further work. Alternatively, string-style plugs of different sizes can be purchased at any motorcycle, bicycle, or auto parts store and substituted for those included in a kit. Just make sure the tool\u2019s insertion needle eye can accommodate the larger plug diameter or they may prove uselessly incompatible when needed.<\/p>\n\n
