Tire with arched spokes

A non-pneumatic tire comprising:

• an inner annular band;
• an outer annular band constructed of a polymeric material and having a reinforcement structure embedded therein;
• and
• a plurality of spokes extending from the inner annular band to the outer annular band, wherein the spokes are configured to carry a load in compression and in tension, and wherein each spoke includes:
• a first concave sidewall,
• a second concave sidewall opposite the first concave sidewall, wherein a bottom portion of the first concave sidewall is connected to a bottom portion of the second concave sidewall, and
• an upper convex arch having a first end connected to the first concave sidewall and a second end connected to the second concave sidewall, such that the first concave sidewall, the second concave sidewall, and the upper convex arch form a closed geometric shape.

A tire comprising:

• a first hoop;
• a second hoop;
• and
• a plurality of spokes extending from the first hoop to the second hoop, each spoke including:
• a first sidewall having a concave shape when the tire is in an unloaded condition,
• a second sidewall opposite the first sidewall, wherein the second sidewall has a concave shape when the tire is in an unloaded condition, and wherein a bottom portion of the first sidewall is connected to a bottom portion of the second sidewall, and
• an upper member having a first end connected to the first sidewall and a second end connected to the second sidewall, such that the first sidewall, the second sidewall, and the upper member form a closed geometric shape, wherein the upper member has a convex shape when the tire is in an unloaded condition.

A non-pneumatic tire comprising:

• a first polymeric band;
• a second polymeric band;
• and
• a web extending from the first polymeric band to the second polymeric band, wherein the web is configured to carry a load in compression and in tension, and wherein the web includes:
• a plurality of U-shaped spokes, each U-shaped spoke having a concave portion, and a pair of radial stems extending from the concave portion, wherein each stem directly contacts the first polymeric band, and wherein the concave portion does not directly contact the first polymeric band and does not directly contact the second polymeric band, and
• a plurality of members, wherein each member directly contacts a concave portion of at least one of the U-shaped spokes, and wherein each member directly contacts the second polymeric band.
