Abstract
A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring and a circumferential tread extending about the outer ring. The circumferential tread includes a band layer constructed of a single material and a tread rubber layer directly attached to the band layer.
Claims19
A non-pneumatic tire comprising:
- an inner ring having an axis of rotation;
- an outer ring coaxial with the inner ring;
- support structure extending from the inner ring to the outer ring;
- and
- a circumferential tread extending about the outer ring, the circumferential tread including a seamless cylinder constructed of a solid, metallic material extending across a width of the tread and a tread rubber layer directly attached to the seamless cylinder, wherein the seamless cylinder has a diameter between 20-50 inches and a thickness between 0.010 inches and 0.300 inches.
A method of making a non-pneumatic tire, the method comprising:
- providing an assembly with an inner ring, an outer ring coaxial with the inner ring, and support structure extending from the inner ring to the outer ring;
- providing a seamless cylinder about the outer ring, the seamless cylinder being constructed of a solid, metallic material extending across a width of the tire, wherein the seamless cylinder has a diameter between 20-50 inches and a thickness between 0.010 inches and 0.300 inches;
- and
- providing tread rubber about the seamless cylinder.
A non-pneumatic tire comprising:
- an inner ring having an axis of rotation;
- an outer ring coaxial with the inner ring;
- support structure extending from the inner ring to the outer ring;
- and
- a circumferential tread extending about the outer ring, the circumferential tread including a seamless cylinder constructed of a solid, metallic material extending across a width of the tread, wherein the seamless cylinder has a diameter between 20-50 inches and a thickness between 0.010 inches and 0.300 inches, and wherein the seamless cylinder has a surface with an average surface roughness of less than 25 microns.
