If it's a really slow leak, you might even think you're imagining it—maybe it lost a little pressure due to cold weather or a similar phenomenon. So you fill it and go on your way. That is until your Tire Pressure Management System sets off a holiday tree full of warning lights on your dashboard. Repair or Replace? Now the question becomes whether to replace the tire or try and fix it. Before you plunk down a bunch of Benjamins, try to locate the puncture. Most can be repaired with a tire plug. This tried and true method utilizes a section of strong cord coated with rubbery tar to stop the leak. In use for decades, it has proven very reliable. Traditional Tire Plugging Plugging a tire the traditional way, while effective, is a messy, arduous process for the do-it-yourselfer. First, you locate the puncture, then you use a special round file-type tool to widen and clean the hole, then you wrestle a gooey piece of tar-coated plug into the needle end of the reaming tool, and then shove the whole thing as hard as you can through the hole and pull it back out. If it doesn't go in easily, it means that you didn't widen the hole enough and have to start all over again. The Dynaplug This small tool has revolutionized the task of plugging a slow leak on a tire. This all-in-one tool shaped like a short screwdriver doesn't look like much at first. Gone is the reaming tool, and the plugs themselves didn't look sturdy enough. All in all, how could this slick-looking system possibly make a dirty job any easier? But it does. No more enlarging the puncture hole, no more threading, no more wasted plugs, no more reaming. With Dynaplug, repairing a tire is a simple, one-step process. How It Works The Dynaplug system uses plugs made from strong bits of sticky rubber that are attached to a brass tip. This entire unit is inserted into the end of the Dynaplug's applicator, which looks similar to a screwdriver handle. Then all you do is remove the nail or any other object that is causing your tire to leak, insert the brass tip into that hole, then pull it out. The sticky plug seals the hole, leaving a tail that can then be cut flush to the tire. That's all there is to it. Not Just for Car Tires There are Dynaplug tools available for just about any size tire, from the largest trucks and SUVs to bicycles to the tire on your wheelbarrow. The traditional tool retails for about $60 and comes with an assortment of ready-to-go plugs. An assortment of smaller sizes, including the compact Racer, are available for bicycles, and some even come with handlebar mounts. Replacement insertion tubes are available for all sizes and styles as well.
