Quote: " Tubeless ready tires don’t have the sealed casing that UST tires (see below) do. That makes them lighter, and also means they require sealant to hold air.
Tubeless Compatible: A tubeless-compatible wheel or rim is one in which the rim has a bead lock, but the rim bed itself is not sealed. Some companies use “tubeless ready” and “tubeless compatible” as synonyms. In either case, the components needed to run the wheel and tire combo as a tubeless setup are the same: a sealed rim bed, tire with a tubeless bead lock, and sealant." |
Whether or not this is true is irrelevant, because letting the wheel sit overnight will simply pool the sealant to downward facing part of the tire. riding the tire will spread the sealant and therefore assist in this allowing the thinner casing to hold air better over time. the sealant is not supposed to really dry inside the tire (though it will over time) to 'seal it,' certainly not after 24 hours. but it will lay a wet film over it sure, increasing the mass of rubber and thereby allowing less air to escape i guess. All rubber will allow air to escape the tire eventually, which is why you have to pump it up.
