Did you know that you should be refreshing the tire sealant in your bike tires every six months? And if youre riding in hot and dry conditions, you might need to do it even more frequently. Regularly refreshing your tire sealant is crucial if you want to avoid slow leaks, and even worse, flats! The good news is that this is a bike maintenance task that even the most mechanically uninclined folks can manage. In this guide, Ill walk you through the simple steps to refresh the sealant in your tubeless tires. Why Refresh Your Tire Sealant?Tire sealant works by filling small punctures and creating an airtight seal, allowing your tubeless tires to hold air even without an inner tube. If youve ever heard a sudden sudden rush or air gushing out of a puncture, only to have it bubble and seal up within a moment or two, then youve seen tire sealant in action! However, over time, the sealant can dry out, especially in hot and dry climates, losing its effectiveness. By refreshing the sealant regularly, you ensure that your tires are always ready to handle whatever the trail or road throws at them.What Youll NeedBefore we get started, youll need a few essential tools and materials:Tire sealant: I recommend using Stans NoTubes Tire Sealant, but there are plenty of other popular brands including Orange Peal. Buy a big bottle, and it will last for a while. Valve core remover tool: This tool is essential for removing your valve core, and replacing it when your done. Injector syringe or a sealant bottle with a nozzle: Either will work to inject the sealant thru the valve. Personally, I like the small 2 oz Stans bottles. They are cheap, convenient, and you can refill them later.Bike pump: Youll need this to inflate your tire after adding the sealant.Step 1: Prepare Your SealantWhether youre using a bottle with a nozzle (like me) or youre using an injector syringe, fill it up with the appropriate amount of sealant. For road tires, youll need about 2 oz of sealant. For mountain bike tires, youll want between 4 and 6 oz, depending on the width of your tires. The fatter the tire, the more sealant youll need. For instance, for my 2.2 mountain bike tires, I add adding 4 oz of sealant, which equates to two of the small 2 oz bottles.Step 2: Remove the Valve CoreNext, use your valve core remover tool to take out the valve core. Place the tool on the valve and turn it counter-clockwise until the core is completely loose. There will be a big rush of air as all of it is released from the tire. Be sure to set the valve core somewhere safe so you dont lose it.Step 3: Add the SealantNow its time to pour the sealant into the valve. Go slowly to prevent the sealant from overflowing. Sometimes, you might encounter a clog in the valve due to old, dried-out sealant. If this happens, use something long and skinny, like the end of a hex wrench, to push the clog loose. This will allow the new sealant to flow in smoothly.Step 4: Reinstall the Valve CoreOnce youve filled the tire with the appropriate amount of sealant, its time to reinstall the valve core. Finger-tighten the valve core as much as you can, then finish tightening it with the valve core remover tool. This ensures that its securely in place and wont leak air.Step 5: Inflate and Distribute the SealantThe final step is to inflate your tire to the desired pressure using your bike pump. Once inflated, give your tire a spin to help distribute the sealant evenly throughout the tire. This helps ensure that the sealant can quickly fill any punctures that might occur while youre riding.Step 6: Repeat With Your Other TireThat was the process for a single tirebut your bike has two! Repeat the whole process on your other tire. Additional TipsKeep a rag handy: Even the best of us spill a little tire sealant during this process. Just wipe it up right away or it will become sticky and hard to clean. (Dont ask me how I know this). Store sealant properly: Keep your sealant bottles tightly sealed and store them in a cool, dry place to prevent them from drying out.Use quality sealant: Not all sealants are created equal. Using a high-quality sealant like Stans NoTubes can make a significant difference in performance and longevity.If replacing the tire, just pour the sealant in: If your tubeless tire is already seated (aka inflated and holding air), the easiest way to add sealant is using the process I described it here. If, however, you are replacing your tubeless tire or setting them up tubeless for the first time, you can pour sealant directly into the tire while its partially off the rim rather than thru the valve.
