It is recommended to use about 50 ml of sealing fluid in a road tire, 70-80 ml in a gravel tire and 100-120 ml in an MTB tire. When installing tubeless tires for our wheels, we use Stan's fluid.
The amount of fluid should be adjusted according to the width of the tire. For road tires, it is not recommended to use less than 50 ml of fluid, because in a puncture situation, high pressure can cause partial loss of fluid before it is effectively distributed and seals the punctured tire.
It is recommended to regularly refill about 20-50 ml of sealing fluid every 2-3 months, however, depending on the intensity of use and tire punctures, it may be necessary to refill more often. The easiest and fastest way to refill the fluid is to pour it through the valve after first unscrewing the end of the cartridge (instructional videos in the second part).
Additional recommendations about using tubeless
- It is not recommended to mix fluids from different manufacturers. If you change the brand of fluid, clean the tire thoroughly.
- If you're not sure if there's enough sealing fluid in the tire, a simple way to find out is to pull the wheel off the bike and shake it vigorously. Ideally, you should hear the characteristic sound of sloshing fluid inside the tire. If you don't hear this sound, it's a sign that the tire's fluid should be topped up.
- Before topping up the fluid after a long period of not using the bike, it is important to thoroughly clean the tire and rim. The purpose of this process is to remove any residual old sealing fluid and any debris.
- If the bicycle will not be used in the post-season, it is recommended to remove the sealing fluid from the tires to avoid drying out the fluid and losing its sealing properties. Alternatively, if the bicycle is not used for a long time, the wheels can be turned every 1-2 weeks so that the fluid remains evenly distributed inside. Good-quality fluid will retain its properties after extended periods of non-use, as long as it has not dried out in the tire.
- Regularly check the condition of the valve and its tightness. An improperly installed valve can lead to loss of pressure. In addition, the valve cartridge often becomes clogged with residual sealing fluid, making it much more difficult to pump the wheel, so it's a good idea to clean it thoroughly every few months or replace it with a new one.
- Be sure to check the maximum allowable pressure on the tire and follow the manufacturer's recommendations. The pressure in tubeless tires is lower than that used in tires with an inner tube, in order to increase driving comfort, improve grip and traction.
