So you’ve found yourself putting air into the same tire after filling it up just a few days ago and your wondering what you can do to fix the apparent slow leak without breaking your wallet for some new rubber.
As you probably know, there are several ways to fix a slow leak once it’s been discovered but determining where exactly it’s leaking from can be a daunting task. To avoid removing the tire from the rim completely to patch it from the inside and to avoid finding bubbles with soapy water to plug the leak, consider buying a $10 bottle of ‘Slime tire sealant’. Slime has survived the test of time, having been around since 1989, and not only repairs leaky tires but also seals future leaks when the tire is punctured (up to ¼ inch diameter).
In order to fix the slow leak using slime, as mentioned in the accompanying video, you’ll need a car jack, an air compressor, a tire gauge and the obvious bottle of slime. Any car jack will do, it doesn’t need to be a floor jack as seen in the video and a simple scissor jack can be used which is usually found in the trunk of any car.
The first step is parking the car in a position where the valve stem is closest to the ground because the slime will enter the tire easiest with some help from gravity! A word of warning, even though the tire doesn’t need to be off the ground by much to do this right, this is a good time to check the owners manual for scissor jack instructions and where to lift the car when using a floor jack.
Once the jack is propping up the tire, remove both the valve cap and the cap to the slime bottle, which you will use to remove the actual valve core. The valve core is the little apparatus inside the valve stem that creates a seal when it’s not letting air in the tire. A ‘tire valve stem core removal tool’ can be used to remove the core but the cap to the slime bottle does the job just fine.
Now for the fun part, which is deflating the tire (as the valve core is removed in the last step) and funneling the slime through the valve stem with the tube that comes attached to the ‘Slime’ bottle. On the Slime website, they recommend using 16oz’s per car tire but most everyone in the automotive industry who recommends slime will say that 8oz will be enough per wheel. So, when buying a bottle larger than 8oz, seal the bottle and rinse the tube for best results in using the rest of the bottle.
The slow leak repair is almost complete, all that’s left is screwing the valve core back in, filling the tire up with air and taking the car out for a ride to shuffle the slime around so it can go to work on the leaks. That’s all there is to fixing a slow leak with slime! Make sure you remember to put the valve cap back on!
