Is it true that beads should be seated with the valve core removed?

Removing the valve core during the installation of a tire helps to facilitate the seating of the beads. When the valve core is taken out, air can flow more rapidly into the tire, allowing the tire beads to push against the rim and create a proper seal. This is especially important when working with tires that may be difficult to mount or have tighter tolerances. The absence of the valve core ensures that the air can quickly fill the tire, creating the force needed for the beads to seat properly against the rim profile.

This method is a commonly accepted practice among tire service professionals and can significantly reduce the chances of the tire not seating correctly, which can lead to air leaks or even the tire coming off the rim during use. Once the tire is properly seated, the valve core can be reinserted to maintain tire pressure.
