What are the advantages of a tubeless tire?

Tubeless tires provide clear advantages in speed, comfort, grip and puncture protection. They avoid unnecessary friction between tires and tubes, which reduces the rolling resistance even more than with super light competition tires.
Tubeless tires can be used with a lower inflation pressure without compromising performance. That brings clear advantages in comfort as well as clearly more control in critical situations and on bad surface trails. At the same time, tubeless systems provide a high puncture protection. The danger of blowouts is clearly reduced. A sudden loss of air pressure by burst tubes or valve tear off is excluded. What is more, tubeless systems function perfectly together with puncture protection liquids. Punctures are re-sealed within milliseconds.

What do you need to fit a tire without tube?
  • Schwalbe tubeless tires
  • Airtight tubeless wheel
  • (or tubeless easy tires and tubeless rim tape)
  • Tubeless valve
  • DSealing liquid (e.g. Schwalbe Doc Blue)
  • Montagefluid (z.B Schwalbe Easy Fit)
  • Assembly liquid (e.g. Schwalbe Easy Fit)
  • Track pump with air gauge
  • A rag


You should be familiar with the specific fitting procedure. Otherwise you should leave the fitting to an expert.

What do you have to keep in mind for the fitting?

Fit the tire as usual onto the rim. Be cautious when applying the tire levers. Important: Apply assembly liquid to both tire beads before inflating (1). Make sure the valve is between the beads when inflating (2). Start inflating with a powerful burst of air (track pump or compressor) (3). The tire engages audibly on the rim. Using the rim line, make sure the tire is properly in place (4).

Deflate the tire a little. Remove the valve core (valve key is supplied with Doc Blue) and fill in 60 ml of the puncture protection liquid Doc Blue (5). For road bike tubes 30 ml are enough.


Strictly observe the indications regarding maximum inflation pressure of tire and rim!


Do not use CO2 cartridges. CO2 has a negative effect on the puncture protection liquid.


Be careful in general when using the sealing liquid. It easily causes stains on clothing or pieces of furniture.



Do I have to fill in the fluid through the valve?

No, you can fill the sealing liquid directly into the tire before mounting the second tire bead. A later filling through the valve has the advantage that your working process is cleaner, as the milk is only applied when the tire is already in its place on the rim. This is very convenient in particular with new tire/rim-combinations, where you don’t know yet, whether fitting works without problems.

With common combinations, it is faster to fill in the sealant directly. If you use valves without replaceable valve cores, filling through the valve is impossible.

Why do you need puncture protection liquid?

Real tubeless tires also function without sealing liquid. However, we recommend its use because the combination of tubeless tires and Doc Blue ensures superior puncture resistance. The sealing liquid has no negative influence on rolling

Tubeless Easy tires do not have an absolutely dense butyl coating. They require Doc Blue to ensure permanent tightness.

What can be the reason, if the tire cannot be inflated?

Be sure to use the fitting fluid! Due to the lubricating film between tire and rim, the tire is positioned much more evenly. In an emergency it is possible to get by with soapy water.

Both tire beads must be positioned either side of the valve.

When inflating for the first time, it may also be helpful to remove the valve core in order to increase the air flow.

In very stubborn cases, use a compressor instead of a track pump.

Further reasons for what can go wrong

Leaks can of course happen at the valve or around the rim. In order to determine the leaks, it is necessary to completely immerse the wheel in water. If there are leaks, air is emitting at the valve and/or spoke nipples. This may take a while, because the pressure has to build up in the rim cavity first. Often the problem is in the valve area. Possible remedy: Tighten the valve nut, clean and deburr the contact area valve/rim and replace the valve. If all of this does not help, the cause of the leak may be a defect in the rim joint or a crack in the rim base.

Is it possible to retrofit normal wheels for the fitting of tubeless tires?

With the tubeless rim tape and the tubeless valve from Schwalbe it is possible to seal standard wheels and to make them fit for tubeless use. It is then no longer necessary to invest in new, more expensive wheels, if you want to change.

The Schwalbe Tubeless rim tape is absolutely high pressure and heat resistant. One ply of rim tape is sufficient. Even in the case of a road bike. The Schwalbe tubeless rim tape is available in 6 different widths from 19 to 29 mm.

The Tubeless valve is made of aluminum and very light. The conical valve foot ensures universal fitting on almost all rims. The valve foot is reinforced with metal to prevent it from moving accidentally into the valve hole. The valve nut has an
anti-twist protection to prevent the valve from coming loose unintentionally during the ride. To ensure that the tubeless conversion also works on deep-rim profiles, our product range also includes threaded valve extensions.

Which wheels are suitable for the conversion?

You should only use wheels which are expressly approved by the manufacturer for a tubeless conversion.

This is particularly important in the case of the high-pressure system road bike. This will ensure that the rim will bear the specific loads in the tubeless use and that the tire fits safely on the rim. The complete Spline® series from DT Swiss for example has been tested and approved for the tubeless conversion.

A conversion is often impossible in the case of very narrow rims (13C), rather lowpriced, not welded or double eyelet rims. In these cases it is mostly impossible to ensure an airtight sealing of the rims with the rim tape.

Be cautious in general with rims having only a minimum flange height (clearly under ETRTO standard), such as the Alpha from No Tubes for example. Although these rims are becoming more and more popular due to their light weight, there is an increased risk of derailing. Usually we have a very big safety margin specifically for the risk of derailing. We want to ensure the safe seating of the tire, even when many unfavorable factors occur simultaneously (tolerances of the rim, tolerances of the tire, tolerances of the pressure gauge,  application errors etc.). This safety margin is clearly reduced for such rims with a minimum flank height.

What do you have to keep in mind for the tubeless conversion?

The rim base must be absolutely clean and even. If necessary, remove old glue and grease residues with brake cleaner..

Make sure all spoke holes are fully covered by the rim tape. The best option would be, if the rim tape covered the complete rim base. In most cases, the rim tape is suitable when it is 2-4 mm wider than the rim width.

Pull the rim tape forcefully before applying it, to avoid air bubbles. Let the tape end overlap by approx. 5-10 cm. We recommend that the overlapping is not in the valve area.

Simply press the tubeless valve with the pointed end through the rim tape.

Even though not very popular among road racers, a valve nut is absolutely necessary for the tubeless use in order to fix the valve safely on the rim. The valve nut on the Schwalbe Tubeless valve has an integrated anti-twist protection. This
valve makes inflating a little difficult, but avoids an unintentional opening of the valve during the ride.

Inflating converted rims with a track pump is often impossible. You should expect that you need a compressor when fitting the tire for the first time.

How often do I have to refill or replace the sealing liquid?

Refilling the sealing liquid is only necessary to maintain the protection against punctures. Schwalbe Doc Blue remains active as preventive puncture protection for approx. 2-7 months or approx. 2000 km. After this period it dries out and turns into a rubber film or separates into the individual components (latex and liquid).

By using a needle you can easily test, whether the sealing liquid is still functioning. Simply pierce the running surface and let the tire rotate. Refill sealing liquid if the hole does not seal immediately. The “test hole” is repaired with the new sealing liquid.

What to do in case of a puncture

While riding punctures are automatically sealed and repaired by Doc Blue. Sealing liquid cannot help with large punctures caused by cuts or snake-bites. In these kinds of cases a spare tube is always the best remedy. Remove the tubeless valve and wipe the sealing liquid out of the tire first.

How to use the tirebooster correctly.

Instructions for use & Safety information
The TIRE BOOSTER supports you with Tubeless assembly. All you need is the right tubeless equipment and a suitable high pressure pump with adapter for Presta valves.

1 Clean tire and rim before assembly. 2 Fit the tire onto the rim in the usual way. Coat both tire beads with mounting fluid before you infl ate the tire. 3 Turn the ‘Air Valve’ on the Tire Booster to the CLOSED position. 4 Place the pump head of the Tire Booster onto the valve of the wheel. You can enhance the air fl ow into the tire by using the adapter. Simply remove your current valve core, screw the adapter onto the pump head and screw both together onto the valve stem. 5 Pump up the Tire Booster with your track pump (max. 11 Bar/160 PSI). 6 Open the ‘Air Valve’. You will hear the tire pop into position on the rim. 7 Check the rim line to make sure that the tire is correctly positioned. If further infl ation is needed this can be done through the Tire Booster ONLY whilst the ‘Air Valve’ is in the OPEN position. 8 Remove the pump head. Add a sealing liquid into the tire if required (e.g. Doc Blue Professional) and infl ate the tire again.



  • Do not exceed the maximum air pressure for the tire and rim.
  • Do not exceed the maximum air pressure for the Tire Booster: 11 Bar/160 PSI.

  • Never inflate the bottle with a compressor.
  • Do not use a defect bottle, tire or rim.

  • Do not release pressurized air into eyes or face.

  • Before opening the ‘Air valve’: ensure pump head is attached securely to the valve of your wheel.

  • Protect the bottle from direct sunlight. Avoid temperatures of below -15°C and above +50°C.

  • Store Tire Booster only with ‘Air Valve’ open.
