A truck tray includes a wear resistant lining covering an area of a floor (15) of the truck tray, with the lining including a tiled floor area. The tiled floor area includes (a) a plurality of tiles (3) formed from a wear resistant tough material arranged in a pattern on the tiled floor area and (b) fines of material transported on the tray in use of the tray covering exposed floor areas of the tiled floor area. The shape of the tiles (3) and the pattern of the tiles are selected so that the fines form protective layers of wear resistant material in the exposed areas of the tiled area. One embodiment of the tile has an hexagonal shape and has a key-hole shaped hole in the tile.
