Does anyone successfully use 'tubeless' or 'tubeless ready' tyres WITHOUT sealant? Is this just 'a rose by any other name'? Or is this an MTB thing?
From a Continental site:
"What does Tubeless Ready mean?
Tubeless Ready tires can be used both with and without an inner tube because the tire and wheel rim are designed so that they directly seal each other. In contrast to UST [Universal System for Tubeless] tires, Tubeless Ready tires are much lighter and are therefore air-permeable in the sidewall. This is sealed with a special sealing milk. All mountain bike tires from Continental are Tubeless Ready in the ProTection and Performance formats. The revolutionary Tubeless Ready bead allows easier and less complicated assembly of the tire. For optimum sealing results and use, we recommend using the Continental RevoSealant . If mounted correctly, the system is relatively air-tight and resistant to snake bites with folding or wired-on tires. Voluminous mountain bike tires in particular benefit from this design. Tubeless Ready tires can be ridden with a lower operating pressure [than what - tubeless tyres?]. The risk of punctures is much lower because there is no inner tube that can be punctured. Also, the movement of the tire on the wheel rim has no impact. In addition, the grip, comfort and rolling friction on rough terrain is better."
