How to Add Sealant to Tubeless Tires? – Guide

Adding sealant to a tubeless tire is a simple process that can be done at home with just a few tools. The most important tool you will need is a good quality air compressor. You will also need a funnel and some sealant.

The first step is to make sure your tires are clean and free of debris. Next, add the sealant to the funnel and slowly pour it into the tire. Once the tire is full, use the air compressor to inflate the tire to the proper pressure.

Let the tire sit for 24 hours before riding so that the sealant has time to work its magic.

  • Clean the rim of the tire with rubbing alcohol and a rag
  • This will remove any dirt or grease that could prevent the sealant from adhering to the surface
  • Apply a thin layer of sealant to the inside of the tire
  • Use your finger to spread it around evenly
  • Inflate the tire using a bike pump or air compressor until it reaches its maximum pressure
  • The sealant will help to fill any small holes in the tire and prevent flats
  • Check for leaks by pressing down on each side of the tire with your thumb
  • If there are no leaks, you’re ready to ride!

The Quickest and Easiest Way to Add Tire Sealant

How to Add Sealant to Tubeless Tires


How Often Should You Add Sealant to Tubeless Tires?

Adding sealant to your tubeless tires is an important part of maintaining them. Sealant helps to seal up any small holes or punctures that may occur in the tire, preventing air from escaping. It is generally recommended that you add sealant to your tires every few months or as needed if you notice any leaks.

To add sealant, simply remove the valve core and inject the desired amount into the tire. Be sure to check your tires regularly for any signs of leaks or other damage.

Do You Need to Put Sealant on Tubeless Tires?

There are a few different types of tubeless tires on the market. Some have a sealant already in them, and some don’t. So, do you need to put sealant on tubeless tires?

The answer is no; you don’t necessarily need to put sealant in tubeless tires. However, many people choose to because it can help prevent flats. Sealant works by filling small holes or cracks in the tire so that air doesn’t escape.

If you do decide to put sealant in your tubeless tires, make sure to use a compatible product. Some sealants can damage the tire or cause it to leak air. Read the labels carefully before making your purchase.

Do You Need to Remove the Old Sealant before Applying New Tubeless?

It’s generally a good idea to remove the old sealant before applying a new tubeless sealant. This ensures that the new sealant can properly adhere to the tire and rim interface and form an effective seal. It also helps to prevent any contaminants from the old sealant from affecting the performance of the new sealant.

How many sealants Do I Need to Top off a Tubeless Tire?

When it comes to topping off a tubeless tire, the amount of sealant you’ll need will depend on the size of the tire. For example, a 29-inch tire will require more sealant than a 26-inch tire. As a general rule of thumb, you’ll want to use about 2 ounces of sealant per tire.

This will ensure that your tires are properly sealed and won’t lose air over time. If you’re unsure how much sealant to use, it’s always better to err on the side of too much rather than too little. This way, you can be sure that your tires will stay properly inflated and won’t give you any trouble down the road.


Adding sealant to tubeless tires is a great way to prevent flats and extend the life of your tires. Here’s a step-by-step guide on how to add sealant:

1. Start by removing the valve core from the tire. This will allow the sealant to enter the tire more easily.

2. Next, add the sealant to the tire. You’ll want to use enough so that it covers the entire inside surface of the tire.

3. Once you’ve added the sealant, replace the valve core and inflate the tire to its proper pressure.

4. You’re now ready to ride! If you do get a flat, simply remove the affected tire and add more sealant as needed before re-inflating it.
