PNEUMATIC TIRE
Provided is a pneumatic tire including, on an outer surface of its sidewall portion, a decorative portion including a print layer and a protective layer located on a tire outer side of the print layer. The decorative portion further includes an intermediate layer located between the print layer and the protective layer. When a storage modulus of the print layer, a storage modulus of the protective layer, and a storage modulus of the intermediate layer are respectively defined as E1′, E2′, and E3′, the following relational expression is satisfied: E2′>E3′>E1′.

PNEUMATIC TIRE
First direction ridge patterns and second direction ridge patterns are lined-up alternately at a tire side portion. Plural main ridges 22A through 22D and sub-ridges 26A through 26D, which project-out from a bottom surface 18A, are formed at a first direction ridge pattern 20. The respective ridges are disposed in parallel such that ridge extending directions are a same direction. Light reflection patterns are different at a main ridge region 24 and a sub-ridge region 28.
TRIPLETUBE TIRE
The present application relates to a tire (6) comprising: a tread portion (8) and side walls (10), said tread portion (8) and side walls (10) defining a main air chamber (12); at least two auxiliary chambers (14, 16, 18) formed in the tread portion (8); and an air transfer device (28) for transferring air between the main air chamber (12) and each of the auxiliary air chambers (14, 16, 18).
Pneumatic tire
A pneumatic tire of the present technology is a pneumatic tire provided with a tread portion, side wall portions and bead portions, a plurality of circumferential grooves extending in the tire circumferential direction being provided in the tread portion, and a belt-shaped sound-absorbing member being bonded via an adhesive layer to the tire inner surface in a region corresponding to the tread portion along the tire circumferential direction, wherein the width W of the sound-absorbing member is from 70% to 95% of the tire ground contact width TCW, and the total width of the circumferential grooves included in the region in the tire width direction in which the sound-absorbing member is disposed is from 25% to 40% of the width W of the sound-absorbing member.

PNEUMATIC TIRE
A pneumatic tire includes, on a surface of a side rubber provided on sidewall portions, a two-dimensional code in which a dot pattern is formed by two types of gray scale elements distinguishable from each other by irregularities on the surface. Dot holes are formed in the two-dimensional code, corresponding to dark elements of the gray scale elements. The side rubber is a diene rubber including butadiene rubber, and when A is a blended amount of the butadiene rubber relative to 100 parts by mass of the diene rubber contained in the side rubber and when B is a blended amount of carbon, a ratio A/B and a hole depth D (mm) from an opening of the dot hole to a hole bottom satisfies a relationship of 1.1≤(A/B)/D≤6.0.
Aircraft tire
An aircraft tire capable of suppressing rubber tire wear during landing and shocks which accelerate or decelerate an aircraft at touchdown includes, on a side of a tire body constituting an outer peripheral part of an aircraft wheel, a protrusion for receiving flight wind pressure. The wheel is rotated ahead of the touchdown by the action of the wind pressure received by the protrusion in a direction in which the wheel rotates during a landing roll. Weight is inserted into a hollow part of the protrusion. Through use of centrifugal force on the weight in association with a rotational motion of the wheel, the protrusion is deformed to change its wind pressure receiving area for bringing rotational speed of the wheel ahead of the touchdown close to a rotating speed of the wheel that is consistent with a flying speed of the aircraft making the touchdown.
