How To Inflate Tubeless Bike Tires?

A lot of cyclists would not give a second thought on whether the bike is using tubeless or tube tires till something goes wrong. Tubeless tires are becoming popular mainly because they are lighter and they have fewer flats and give better performance. How to inflate tubeless bike tires?

To pump tubeless tires on a mountain bike you can use a tubeless tire booster, compressor, or foot pump for tubeless tires. When you connect the pump to the tire, you can now proceed to inflate your tire. The tightening of your tire will enable it to build enough pressure and thereafter form a seal between the tire and the rim.

In this post, we will go through how to inflate tubeless bike tires. Let’s get started!

How To Inflate Tubeless Bike Tires?

Tubeless tires have been around for a good few years for mountain bikes and road bikes. The biggest benefit is tubeless tires are self-healing but the biggest benefit is that it helps to prevent pinch flats which happen when the tube is pinched between the ground and the rim.

To inflate a tubeless tire is a fairly straightforward process. The steps are as follows.

Clean The Rim That The Tire Sits On

The first step when you need to inflate a tubeless tire is to clean the rim that the tire sits on to make the contact between the rim and the tire strong. This ensures no air loss as there is no tube.

This can be done using a dry, clean rag without necessarily having to use water and soap. And you need to add the sealant if there is none.

Ensure That The Valve Is At A 3 Or 9 O’Clock Postion

You need to ensure that the valve is in a 3 or 9 o’clock position as if it is a 6o’clock position you will get fluid build-up. And from the12o’clock position, it will also affect the valve. Open and remove the valve.

Use Straps Or Ties To Secure The Tire

Straps or ties can be used to secure your flat tire. You can hold and tighten your tire by wrapping whatever you are using around the length of your tire. The straps help to hold the tire in place when starting to fill with air.

Inflate The Tire

By using a compressor or tubeless foot pump, you can now proceed to inflate your tire. The tightening of your tire will enable it to build enough pressure and thereafter form a seal between the tire and the rim.

As the tire inflates it shall form its own seal due to the pressure build inside it. The straps or ties shall have been overturned by the pressure thus requiring you to remove them.

Finishing Up

You can finish off inflating the tire and put the valve back and close.

Do You Need A Special Pump For Tubeless Tires?

There are special pumps for tubeless tires available like a tubeless tire booster and foot pumps for tubeless. You can use air compressors to inflate your tubeless tires.

Some additional advantages of using it such as fastness, ease, and better performance may make you go for the special pump. Special pumps also enable the tire to form a perfect seal with the rim.

What PSI Should My Tubeless Tires Be?

Good tire pressure for tubeless mountain bike tires is around 26 psi on the front and 28 psi on the rear tire. For road bikes, the tire pressure is around 80 psi on the front and 83 psi on the rear tire. Also on the sidewalls of your tire, the recommended pressure level is stamped.

There are many factors to consider such as the overall weight of the bike including the rider, and also the conditions of the road. The range of the pressure level should lie between the maximum and the minimum of that on the sidewall of your tire.

How Long Do Tubeless Tires Last?

The lifespan of a tubeless tire depends on several factors especially the way it is going to be used and how often. Tubeless tires are technically self-healing which sounds too good to be true but the sealant needs to be replaced.

A lot depends on the sealant that is used. There are 2 main sealants which are fiber-based and latex-based. You can expect the latex-based sealant to last 8000 miles and fiber-based sealants can last a lot longer.

If your tire develops cracks, gets cut, or bulges, it is better to change it for safety reasons regardless of the time it has lasted since you buy it.

Why Won’t My Tubeless Tire Inflate?

There are several reasons that can make your tire not inflate. Firstly, before inflating especially a new tire, you need to check whether.

  • It is tubeless compatible.
  • The tire beads are seated the whole way round.
  • Is the nut in the valve is properly tightened.
  • You can hear sealants when you shake your tire.

If by any chance your tire isn’t inflating and it meets all these conditions, it means that there might be an opening existing in it. This might be the cause of it not inflating.

Wrapping Up

Finally, to pump tubeless tires on a mountain bike you can use a tubeless tire booster, compressor, or hand pumps for tubeless. The tubeless tires do have the benefit of helping to prevent pinch flats and offer better performance.
