Tubeless tyres are becoming more and more popular with road, gravel and mountain bikers. Tubeless systems are less prone to punctures; the tyres are lighter, small punctures seal quickly and rolling resistance is lower. If you want to put a tight-fitting tubeless-ready tyre on your rim for the first time, you'll need sealant, tubeless rim tape, tubeless valves and a special tubeless pump. It's virtually impossible to inflate a tubeless tyre with a normal hand pump. With a good floor pump, it can work, but with a tubeless pump, the first inflation is almost guaranteed to succeed. Tubeless pumps generate extremely high pressure in a short time so that the tyre quickly settles onto the rim and no more air can escape. Then just distribute the sealing milk evenly in the tyre and you're golden!
