A composite PDU tire in an aircraft cargo handling system may include a plurality of bonded regions configured to propel cargo within an aircraft cargo bay. The composite tire may include edge regions that are stiffer than a cylindrical region. The edge regions may be configured to have a greater wear resistance and abrasion resistance relative to the cylindrical region. The cylindrical region may be configured to have greater traction relative to the edge regions. The edge regions may include a fillet profile and may be configured to reduce chipping as cargo climbs across the tire.

To provide a tire having a resin tire skeleton member and improved in pressure-resistant performance and reliability during rolling.SOLUTION: A tire includes a resin tire skeleton member having a bead part 12, a side part 14 which is continuous to outside in a tire radial direction of the bead part, and a crown part 16 which is continuous to inside in a tire width direction of the side part, and a tread 34 which is arranged outside in the tire radial direction of the crown part. The crown part includes a belt layer 28 where one or a plurality of reinforcement cords are coated with a resin. In the tire skeleton member, a range between an end outside in the tire width direction of the belt layer and the side part is formed of only a resin. A product of the thickness and the elastic modulus of the resin constituting the tire skeleton member in the range is 200 MPa mm or more and 600 MPa mm or less.SELECTED DRAWING: Figure 1

To provide a tire which uses thermoplastic elastomer and is excellent in stability.SOLUTION: A tire has a tread part and a side wall part which are formed of thermoplastic elastomer composition. A deviation A in a tire radial direction on an outermost surface of a tread crown part satisfies an expression (1) when a prescribed air pressure is filled after performing normal rim assembly: A≤3.0% ...(1). A total thickness T (mm) of the tread crown part and an outer diameter Dt (mm) of the tire satisfy an expression (2): T / Dt≤0.034 ...(2).<Prescribed air pressure> In a case that a virtual volume V of the tire is 15000 cm3 or more: 250 (kPa). In a case that the virtual volume V of the tire is less than 15000 cm3: 0.0152×V+22.553 (kPa). The virtual volume V (mm3) of the tire is calculated based on an outer diameter Dt (mm) of the tire, a sectional width Wt (mm), a cross section height H (mm) when the normal rim assembly is performed and an inner pressure is air pressure: V={(Dt / 2)2-(R / 2)2}×π×Wt; and R=Dt-2H.SELECTED DRAWING: None
