tubed
Definition
Adjective 1. Having an inner tube: Describes a pneumatic tire that contains a separate, inflatable inner tube to hold the air, as opposed to a "tubeless" tire where the tire itself forms an airtight seal with the wheel rim.

Notes on Meaning
"Tubed" has a very narrow and specific meaning in modern English, almost entirely confined to the context of tire technology. It should not be confused with the more general verb form "tubed" (past tense of "tube," meaning placed in or conveyed by a tube).
