A cart is disclosed having a rigid base with a plurality of cutouts, bottom and top sides, and at least one peripheral edge. The bottom side has at least one removable, lockable caster at each bottom side corner. The cart has a rigid cradle with bottom, back, and top sides, and at least one peripheral edge. The opposing sides of the top side have horizontal rollers mounted on flanges. The cradle has a handle, tool hooks, a lug nut tray, and a wheel retainer. An actuating lift coupled between and centered on the base top and cradle bottom is movable between a lowered position and a raised position. The base has an elevated portion and is switchable between raised and lowered configurations, setting the cradle's maximum height, by removing the casters and decoupling the lift from the base; flipping over the base; reattaching the casters; and recoupling the lift.

A storage array includes one or more tiers including a plurality of roller pairs and at least one motor for spinning each roller pair. Plates are positioned between each roller pair. A horizontal nudge is positioned above each plate moves tires horizontally within the storage array. A tire is moved longitudinally within the storage array by causing a roller pair bearing the tire to spin followed by lifting the plate below the tire, thereby causing the tire to roll forward or backward within the storage array. The storage array may be coupled to a distribution system including a plurality of channels including a planar or concave bottom surface over which tires roll and vertical sidewalls extending upwardly from the bottom surface. Accelerators, brakes, junctions, and elevators may be positioned in channels in order to control movement of tires through the distribution system.

The present disclosure relates to a process and a system for manufacturing an HSST tyre, as well as the HSST tyre manufactured by the same. The process for manufacturing an HSST tyre includes a cleaning step, a spraying step, and a forced-cooling step. The cleaning step includes an air-drying procedure for evaporating the isopropanol solution on the tyre to be treated with air-drying gases. The forced-cooling step is configured to forcibly cool the tyre to be treated that has been sprayed with the high molecular organic material. By means of accurate design for each step and procedure, the relying on operator's experience is eliminated and thus the performance stability of the HSST tyre is guaranteed. By means of the air-cooling procedure and the forced-cooling step, the time taken to manufacture an HSST tyre is substantially shortened, making it possible to produce the HSST tyre in a large scale.
