A groutless floor tile system, comprising: - a plurality of groutless floor tiles, each groutless floor tile comprising: - a durable component disposed on a surface of a substrate; and - a first coupling member disposed on an edge of the substrate, the first coupling member comprising a groove; - a second coupling member disposed on at least another edge of the substrate, the second coupling member comprising a tongue; wherein said first and second coupling members are configured to couple two adjacent groutless floor tiles and are provided with vertically active locking portions, which, when the coupling members of two such groutless floor tiles cooperate with each other, effect a locking in a vertical direction and wherein said first and second coupling members are also provided with horizontally active locking portions, which, when the coupling members of two such groutless floor tiles cooperate with each other, effect a locking in a horizontal direction; wherein the vertically active locking portions are substantially formed by said tongue of said second coupling member and said groove of said first coupling member, characterized in that - the substrate is larger than the durable component, such that the durable component is disposed within a groove defined within the substrate and the surface of the substrate comprises at least a portion that extends horizontally beyond the durable component; wherein the substrate includes a flange portion disposed along the side edges of the substrate and said flange portion includes said first and said second coupling member and wherein at least a portion of the first coupling member is disposed beneath at least a portion of a durable component of the adjacent tile when adjacent groutless tiles are coupled, and in that - said tongue of said second coupling member and said groove of said first coupling member, when the coupling members of two such groutless floor tiles cooperate with each other, engage at least partially vertically underneath said portion of the substrate's surface that extends horizontally beyond the durable component. - a plurality of groutless floor tiles, each groutless floor tile comprising: - a durable component disposed on a surface of a substrate; and - a first coupling member disposed on an edge of the substrate, the first coupling member comprising a groove; - a second coupling member disposed on at least another edge of the substrate, the second coupling member comprising a tongue; - the substrate is larger than the durable component, such that the durable component is disposed within a groove defined within the substrate and the surface of the substrate comprises at least a portion that extends horizontally beyond the durable component; wherein the substrate includes a flange portion disposed along the side edges of the substrate and said flange portion includes said first and said second coupling member and wherein at least a portion of the first coupling member is disposed beneath at least a portion of a durable component of the adjacent tile when adjacent groutless tiles are coupled, and in that - said tongue of said second coupling member and said groove of said first coupling member, when the coupling members of two such groutless floor tiles cooperate with each other, engage at least partially vertically underneath said portion of the substrate's surface that extends horizontally beyond the durable component.
