In some embodiments, the tile lengths in an installation are the same and the tile widths are customized to a particular section of the aircraft or other vehicle in which they are installed. ## Claims ### Claim 1 A method for providing carpet tiles for a floor of a mass transit vehicle having at least a first vehicle floor section having a length and a width and a second vehicle floor section having a length and a width that is different than the width of the first vehicle floor section, the method comprising: (a) forming a carpet web having an underside, a carpet web width and a carpet web length; and (b) forming carpet tiles from the carpet web by: i. providing a plurality of vertical partition lines extending along the carpet web length to divide the carpet web into carpet web sections across the carpet web width, wherein each carpet web section comprises a carpet web section width and wherein the carpet web section widths are substantially equal; and ii. providing a plurality of horizontal partition lines extending across the carpet web width, wherein a first distance between a first pair of adjacent horizontal partition lines substantially equals the width of the first vehicle floor section and wherein a second distance between a second pair of adjacent horizontal partition lines substantially equals the width of the second vehicle floor section, wherein each tile of a first set of tiles comprises a tile width substantially equal to the carpet web section width and a tile length substantially equal to the first distance and wherein each tile of a second set of tiles comprises a tile width substantially equal to the carpet web section width and a tile length substantially equal to the second distance. ### Claim 2 (depends on 1) The method of claim 1, further comprising (c) orienting the first set of tiles along the length of the first vehicle floor section so that the tile length of each tile of the first set of tiles spans the width of the first vehicle floor section and (d) orienting the second set of tiles along the length of the second vehicle floor section so that the tile length of each tile of the second set of tiles spans the width of the second vehicle floor section. ### Claim 3 (depends on 1) The method of claim 1, further comprising positioning adhesive on the underside of the carpet web. ### Claim 4 (depends on 3) The method of claim 3, wherein positioning adhesive on the underside of the carpet web comprises positioning adhesive strips along the length of the underside of the carpet web. ### Claim 5 (depends on 4) The method of claim 4, wherein at least some of the plurality of vertical partition lines are provided within the adhesive strips. ### Claim 6 (depends on 4) The method of claim 4, wherein a portion of an adhesive strip extends along at least one edge of each tile of the first and second sets of tiles. ### Claim 7 (depends on 6) The method of claim 6, wherein a portion of an adhesive strip extends along at least two edges of each tile of the first and second sets of tiles. ### Claim 8 (depends on 3) The method of claim 3, wherein the adhesive comprises a releasable adhesive. ### Claim 9 (depends on 6) The method of claim 6, further comprising orienting the first set of tiles along the length of the first vehicle floor section so that the tile length of each tile of the first set of tiles spans the width of the first vehicle floor section and so that an edge of each tile of the first set of tiles positioned along the length of the first vehicle floor section abuts an edge of an adjacent tile of the first set of tiles positioned along the length of the first vehicle floor section. ### Claim 10 (depends on 9) The method of claim 9, wherein abutting edges of adjacent tiles of the first set of tiles comprise a portion of an adhesive strip. ### Claim 11 (depends on 1) The method of claim 1, wherein the carpet web comprises at least one backing layer comprising a filler selected from the group consisting of glass spheres, fumed silica, a silica-based foam, and combinations thereof. ### Claim 12 (depends on 11) The method of claim 11, wherein the filler comprises glass spheres and wherein the glass spheres comprise hollow glass microspheres. ### Claim 13 (depends on 1) The method of claim 1, wherein the carpet web has a weight of less than about 82 ounces per square yard. ### Claim 14 (depends on 1) The method of claim 1, wherein the carpet web has a weight of less than about 56 ounces per square yard. ### Claim 15 (depends on 1) The method of claim 1, wherein the first and second sets of tiles comply with one or more of the following standards for flame, smoke or toxicity: FAR 25.853; BSS 7239; BSS 7238; D6-51377 and BSS 7230. ### Claim 16 A method for providing carpet tiles for a mass transit vehicle having at least a first vehicle floor section having a length and a width and a second vehicle floor section having a length and a width that is different than the width of the first vehicle floor section, the method comprising: (a) forming a carpet web having an underside; a carpet web width; a carpet web length; at least one backing layer comprising a filler selected from the group consisting of glass spheres, fumed silica, a silica-based foam, and combinations thereof; and a weight of less than about 82 ounces per square yard; and (b) forming carpet tiles from the carpet web by: i. providing a plurality of vertical partition lines extending along the carpet web length to divide the carpet web into carpet web sections across the carpet web width, wherein each carpet web section comprises a carpet web section width and wherein the carpet web section widths are substantially equal; and ii. providing a plurality of horizontal partition lines extending across the carpet web width, wherein a first distance between a first pair of adjacent horizontal partition lines substantially equals the width of the first vehicle floor section and wherein a second distance between a second pair of adjacent horizontal partition lines substantially equals the width of the second vehicle floor section, wherein each tile of a first set of tiles comprises a tile width substantially equal to the carpet web section width and a tile length substantially equal to the first distance and wherein each tile of a second set of tiles comprises a tile width substantially equal to the carpet web section width and a tile length substantially equal to the second distance. ### Claim 17 (depends on 16) The method of claim 16, further comprising (c) orienting the first set of tiles along the length of the first vehicle floor section so that the tile length of each tile of the first set of tiles spans the width of the first vehicle floor section and (d) orienting the second set of tiles along the length of the second vehicle floor section so that the tile length of each tile of the second set of tiles spans the width of the second vehicle floor section. ### Claim 18 (depends on 16) The method of claim 16, further comprising positioning adhesive strips along the length of the underside of the carpet web. ### Claim 19 (depends on 18) The method of claim 18, wherein at least some of the plurality of vertical partition lines are provided within the adhesive strips. ### Claim 20 (depends on 18) The method of claim 18, wherein a portion of an adhesive strip extends along at least one edge of each tile of the first and second sets of tiles. ### Claim 21 (depends on 18) The method of claim 18, wherein the adhesive strips comprise a releasable adhesive. ### Claim 22 (depends on 20) The method of claim 20, further comprising orienting the first set of tiles along the length of the first vehicle floor section so that the tile length of each tile of the first set of tiles spans the width of the first vehicle floor section and so that an edge of each tile of the first set of tiles positioned along the length of the first vehicle floor section abuts an edge of an adjacent tile of the first set of tiles positioned along the length of the first vehicle floor section, wherein abutting edges of adjacent tiles of the first set of tiles comprise a portion of an adhesive strip.
