[00:00:00] [Larry] Do you have a tire that continuously needs air? Well stop hesitating and fix that leakage. Here are the tools you’ll require for the task: a tire plug set, soapy water, pliers, jack stand, jack, lug nut wrench, gloves and glasses. I’m Larry Kosilla, pro detailer and fitness instructor, for the last 15 years. But when it concerns what’s under the hood, I’m the student. Follow me as specialists teach me how to diagnose, fix, and modify cars on Autoblog’s Wrenched. As you understand there’s absolutely nothing more irritating than a leaking

[00:00:30] tire like this one here. The only thing that I can think of is a spray sealant. Is this something you would utilize? – The expert method to fix this tire would be with a spot and plug. – [Larry] Nails and screws quickly puncture rubber tread and are normally the perpetrator of these kinds of slow leakages. The NHTSA recommends that a proper repair requires both a plug and a patch and ought to just be utilized in choose cases where this is an ideal fix. To assist you comprehend the procedure better, we’re gon na show you how it’s done. However keep in mind this is not a repair work that needs to be

[00:01:00] tried at home. Always consult your manual for the proper automobile jack points on the frame. Before raising the vehicle, loosen the lug nuts while the tire is on the ground, to prevent the wheel from spinning in the air. But, do not eliminate them altogether at this point. Now, lift the vehicle and location the jack stands in the appropriate places and launch the weight of the jack slowly, until the cars and truck is resting on the stand itself. For additional security, leave the floor jack in place as your backup.

[00:01:30] Then, remove the lugs and, of course, the wheel. As you roll the wheel, try to find any obvious metal or perhaps a nail. Often they’re concealed or obscured by the rubber itself. So spray a bottle of soapy water along the tread. The leaky air will cause the soapy water to bubble, letting you know where the object or puncture may be. In our example, the screw is fairly obvious, however marking the location with chalk can be helpful, particularly if it’s a smaller sized leak. If an item is present, eliminate it with pliers

[00:02:00] if it’s a nail or some other metal piece, or just loosen it if it takes place to be a screw. Make certain to use safety glasses and a thick glove as small metal objects might be forced upward by the air as they are removed, so beware. Tire plug kits can be discovered at any automobile shop and usually include a reamer, a plug set up set, and lots of plugs. With the item out of the tread, instantly plunge the reamer into the hole, while minimizing the quantity of air being released. This can be hard to move in and out. The objective is to use the abrasive edges of the reamer

[00:02:30] to clean up the hole prior to requiring the plug material in that tight space. After a number of passes, leave the reamer in the hole and prepare the plug tool by sliding the plug into the opened end. Once the plug’s in location, eliminate the reamer and plunge the plug tool into the air hole. Once again, this tends to require a lot of down force, so towering above the tire can help your take advantage of. Once the plug permeates the tread, quickly pull the tool vertically out to set the plug in location.

[00:03:00] If additional plug product occurs to protrude, or above the tread, you can merely cut it with your snippers. With the tire off the rim, the mechanic can inspect the tire from the within for any damage that might not have appeared previously. Now, with access to the inside of the tire, the mechanic carefully razor blades the excess plug product, then, lightly sands down the area so that the spot can lay flush versus the rubber to guarantee

[00:03:30] a lasting repair work. Next, a chemical cement is completely applied to the sanded location and the patches protective cover got rid of prior to setting up over the tire plug. Finally, a deburring tool is utilized to spread the glue uniformly under the spot to promote the best adhesion prior to re-installing the tire back on the rim. (rock music) Afterwards, test for leakages as soon as again.

[00:04:00] If you see no bubbles, you’re great to go. But it’s always a smart concept to keep an additional eye on the tire in the upcoming days, simply to be sure. Often, during the soapy water test, a leakage is discovered on the sidewall and not the tread. Sadly, these problems are not recommended for plug repair work and will probably require a brand-new tire or even a brand-new rim if a hole has bent the metal substantially. Either way, a plug may not be utilized, and a see to your regional mechanic is required. Your tires on the only thing touching the roadway

[00:04:30] and a sluggish leakage is not gon na disappear by itself. Detect the issue quickly to return on the roadway securely. For more how-to cars and truck repair work videos, go to I’m Larry Kosilla from As always, thanks for enjoying.
