Abstract: A synthetic resin skin material composite, including: a urethane resin skin material including a urethane resin skin layer provided at one surface of a substrate; and a cushion layer that is placed at a surface on an opposite side of the substrate from the surface of the urethane resin skin material at which the urethane resin skin layer is provided; in which the urethane resin skin material has recesses at a side of the urethane resin skin layer, and each of the recesses has a depth in a thickness direction of the synthetic resin skin material composite, such that the recesses extend from the urethane resin skin layer into the cushion layer beyond an interface between the urethane resin skin material and the cushion layer that is present in a region without a recess, as well as a method of producing a synthetic resin skin material composite.

Abstract: A pneumatic tire and a rim includes a noise damper, fixed to a tire inner surface or a rim inner surface with the upper surface facing a tire inner space, and extending in the tire circumferential direction. The noise damper is made of a sponge having a volume ranging from 0.4 to 20% of the volume of the tire inner space. The noise damper is a laterally long and flat, with a maximum thickness ranging from 5 to 45 mm and a width more than the maximum thickness. The upper surface extends along a wavy curve including a hilltop, valley bottoms on each side of the hilltop and slopes extending down to the respective valley bottoms from the hilltop. Each end of the upper surface is terminated at the valley bottoms or the slopes. A thickness from the upper surface to the bottom surface ranges from 1.0 to 15.0 mm.

Abstract: An assembly of a pneumatic tire and a rim includes a band-like noise damper, having the bottom surface fixed to a tire inner surface or a rim inner surface and the upper surface facing a tire inner space in the tire inner space, and extending in the tire circumferential direction. The noise damper is made of a sponge having a volume in the range of from 0.4 to 20% of the entire volume of the tire inner space. In a tire meridian section, the noise damper is of a laterally long, flat sectional shape having a maximum thickness value (tm) from the bottom surface to the upper surface in the range of from 5 to 45 mm and having a width (W1) of the bottom surface more than the maximum thickness value (tm).
