Non-pneumatic tire

Claim 2

1 . A non-pneumatic tire comprising: at least one annular band, wherein said annular band has an inner ring and a deformable outer ring; a plurality of generally flexible web-spokes connecting said inner ring to said outer ring; and a ground contacting tread cap affixed to said annular band.

Claim 3

2 . The non-pneumatic tire of claim 1 , further comprising a deflection limiter.

Claim 4

3 . The non-pneumatic tire of claim 2 , wherein said tire comprises a first annular band having a first inner face and a second annular band having a second inner face opposing said first inner face, and wherein said deflection limiter is sandwiched between said first inner face and said opposing second inner face.

Claim 5

4 . The non-pneumatic tire of claim 3 , wherein said first and second annular bands further comprise: a first fastening means circumferentially spaced around said inner ring on said inner face of said first and second annular bands; a second fastening means circumferentially spaced around said inner ring on said inner face of said first and second annular bands and between said first fastening means, wherein said first fastening means on said first annular band interact with said second fastening means on said second annular band, and wherein said first fastening means on said second annular band interact with said second fastening means on said first annular band to connect said inner rings of said first and second annular bands together; a third fastening means circumferentially spaced around said outer ring on said inner face of said first and second annular bands; and a fourth fastening means circumferentially spaced around said outer ring on said inner face of said first and second annular bands and between said third fastening means, and wherein said third fastening means on said first annular band interact with said fourth fastening means on said second annular band and wherein said first fastening means on said second annular band interact with said second fastening means on said first annular band to connect said outer rings of said first and second annular bands together.

Claim 6

5 . The non-pneumatic tire of claim 3 , wherein said first and second annular bands further comprise; a plurality of first friction attachment means in a surface of said outer ring, wherein said first friction attachments means extend in an axial direction toward an outer face of said first and second annular bands; and wherein said tread cap having an interior surface further comprises; a plurality of second friction attachment means on said interior surface, wherein said second friction attachments means are configured to engage said first friction attachment means on said first and second annular bands, thereby affixing said tread cap to said first and second annular bands.

Claim 7

6 . The non-pneumatic tire of claim 1 , wherein said inner ring, outer ring, and web-spokes of said annular band are made of polypropylene or reinforced nylon.

Claim 8

7 . The non-pneumatic tire of claim 1 , wherein said tread cap is made of polyurethane or polyethylene.

Claim 9

8 . The non-pneumatic tire of claim 1 , wherein said web-spokes have a generalized shape selected from the group consisting of “C”, “Z”, “S”, a sideways “A”, a sideways “M”, a sideways “W”, a sideways wishbone, and combinations thereof.

Claim 10

9 . The non-pneumatic tire of claim 8 , wherein said web-spokes have a sideways wishbone shape.

Claim 11

10 . The non-pneumatic tire of claim 9 , wherein said web-spokes have a double wishbone shape.

Claim 12

11 . The non-pneumatic tire of claim 9 , wherein said web-spokes have a stiff wishbone shape approximating a sidewise “A”.

Claim 13

12 . The non-pneumatic tire of claim 1 , further comprising central hub for attaching said non-pneumatic tire to a machine axel or hub.

Claim 14

13 . The non-pneumatic tire of claim 1 , wherein said non-pneumatic tire is used on a machine selected from the group consisting of tractors, utility vehicles, walk-behind lawn mowers, riding lawn mowers, tillers, cultivators, snow throwers, chipper shredders, chipper shredder vacuums, gas-powered portable DC generators, power sprayers, and power washers.
