"IMPROVED TRAILER JACK USING FULL SIZED SPARE TIRE" ABSTRACT OF THE DISCLOSURE An improved trailer jack (10) has a castor structure enabling use of a full size spare trailer wheel and tire (66) on the jack; the jack has a gear box mechanism (22), a lift post (30) drivable up and down by the gearbox, and a lift element (50) pivotally journaled inside the post; the lift element has an offset structure (F9F2) which raises the spare axle (44) axis (58) up to a level above the bottom of the post and the spare axle is spaced to one side so that when the full size spare wheel and tire is used it pulls up into a locked storage position above and alongside of the trailer tongue (18); when the spare is down, it swivels completely around under the tongue and around the lift post. The trailer (12) is much easier to manually manipulate in a garage or driveway. An improved lift assembly (28) with a unique swiveling lift member having both a trailing offset (62) and transverse offset (64) is utilized. A method of storing and carrying a full-size trailer spare wheel and tire has the steps of securing a jack to a trailer, rotatably mounting a full diameter spare upon a movable spare axle in the jack, lowering the full diameter spare below the trailer tongue and swiveling the spare under the tongue, and then raising the spare alongside and above the tongue into a locked storage position.
