A heavy-duty pneumatic tire includes a section width being equal to or less than 335 mm, an aspect ratio being equal to or less than 55%, and a toroidal carcass extending between axially spaced bead portions through a tread portion and sidewall portions. The carcass includes a carcass ply which includes a main portion and a turn-up portion turned up around a bead core of each bead portion. A belt layer is disposed radially outward of the carcass in the tread portion, wherein a radially outer end of the turn-up portion is located between the main portion and the belt layer in the tread portion. A sheeted rubber layer is disposed between the main portion and the turn-up portions in each sidewall portion.

A motorcycle tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass extending between the bead portions in a toroidal manner. Each of the sidewall portions is provided with a sidewall rubber. In each of the sidewall portions, a minimum thickness (Ts) is 50% or less of a minimum tire thickness (Ta) from a respective one of tread edges to a tire inner cavity surface. A minimum thickness (Ds) of the sidewall rubber is from 0.3 to 1.9 mm.

A tire includes a rubber member and a round tire frame made of a resin material. The resin material includes a thermoplastic elastomer, and has a deflection temperature under load of 150 C. or higher. The thermoplastic elastomer includes a soft segment and a hard segment derived from a polyamide. A minimum number X of carbon atoms present between nitrogen atoms in the main chain of the polyamide in the hard segment and a molecular weight Y of the hard segment satisfy the following Formulae 1 to 3:

A pneumatic radial tire for a passenger vehicle according to the present invention has an appropriate relationship between a tire cross-sectional width SW and a tire outer diameter OD. Also, a method of using the pneumatic radial tire for a passenger vehicle according to the present invention is to use the above radial tire with at least specified internal pressure.

To reduce noise while suppressing increase in rolling resistance, without affecting the formation of a carcass line, provided is a pneumatic tire (10) including: a carcass (13); an inclined belt (14), and an inner liner (17). The inclined belt (14) is disposed on the tire radial outer side of the crown portion of the carcass (13). The inclined belt (14) includes at least one inclined belt layer (16). The inclined belt layer (16) has cords extending as being inclined at 35 or more with respect to the tire circumferential direction. The inner liner (17) has a thickness of 1.5 mm or more at least in part of a side portion (19).

A tire (1) for an electrically assisted bicycle or wheelchair having tire a crown reinforcement, which is radially on the inside of a tread, with the tread being connected to two beads via two sidewalls. The tire has, on at least one of the sidewalls (3) and protruding from the sidewall, a strip (4) of a rubber compound with an axial thickness (ep) that is at least equal to 1 mm and at most equal to 4 mm, at least equal to 10 mm and at most equal to 30 mm. The rubber compound has a Shore A hardness of between 55 and 75, and a glass transition temperature of between ?15? C. and 0? C. The compound forms a smooth outer surface (5) that is intended to come into contact with a drive roller bearing a plurality of indenting elements.

The rolling resistance of a tire has been improved without degrading industrial performance. The sidewall (30) consists of two sub-layers. A first sub-layer (FE1) of thickness E1 and volume V1 provides the expected protection functions of a sidewall as the outer wall of the tire, and a second sub-layer of the sidewall (FE2) of thickness E2 and volume V2 is optimized at low hysteresis to improve rolling resistance. The ratio V1/(V1+V2) of the volumes of the two sub-layers (FE1, FE2) is less than or equal to 0.3. The elongation at break of the compound of FE1 is greater than or equal to 200% measured at a temperature of 100? C., and the viscoelastic loss of the compound of FE2, Tan(?)max, is less than or equal to 0.10.

A run-flat tire ensures run-flat durability with a reduced weight. A tire radial outermost carcass ply of two or more carcass plies has tire widthwise inner ends in a crown portion. A bead filler and side reinforcing rubber have an overlapping part in the tire width direction. In a cross section of the run-flat tire in the tire width direction in a state where the run-flat tire is attached to an applicable rim, filled to a specified internal pressure, and placed under no load, a thickness d1 of a sidewall portion at a midpoint in the tire radial direction between a maximum width position of the run-flat tire and a tire radial outermost position of a bead core is greater than a thickness d2 of the sidewall portion at a midpoint in the tire radial direction between the maximum width position of the run-flat tire and a tread edge.

A tire includes a pair of bead cores, a carcass layer extending between the bead cores, and a belt layer disposed on an outer side of the carcass layer in a radial direction. A tire outer diameter OD (mm) is in a range 200?OD?660. A total tire width SW (mm) is in a range 100?SW?400. A strength Tcs (N/50 mm) per a width of 50 mm of a carcass ply constituting the carcass layer is in a range 17?Tcs/OD?120 with respect to the tire outer diameter OD (mm).
