The amount of sealant required for tubeless tyres depends on the width. As a rule, there should be enough to coat the inside of the tyre wall and leave a small puddle in the bottom of the tyre.
When fitting tyres to use wheels we use the following measurements as a base guide (note that you can use more if you feel it is necessary):
- 23mm tyres – 30ml
- 25mm tyres – 40ml
- 28mm tyres – 50ml
- 32mm tyres – 60ml
- 35mm tyres – 70ml
- 40mm tyres – 80ml
- 3.0" tyres - 200ml
- 2.5" tyres - 150ml
- 2.3-2.4" tyres - 120ml
The sealant is water-based and will eventually dry out. We recommend topping up the sealant levels every 2-3 months depending on weather conditions. If it is extremely hot or the wheels are stored in a warm place then you may need to top up the sealant more often. To top up the sealant, please refer to our tubeless tyre fitting guide here.
