Vehicle tire structure

A vehicle tire structure comprising:

• a tubeless pneumatic tire;
• a wheel, over which said tubeless pneumatic tire is fitted, said wheel and tire defining an annular chamber therebetween;
• means for acoustically compartmentalizing said annular chamber in a circumferential direction of said annular chamber;
• and
• means for defining a space between said means for acoustically compartmentalizing and a radially outermost, inner surface of said tire, said structure having an axis of rotation wherein said means for acoustically compartmentalizing comprises:
• at lease a pair of walls substantially parallel to said axis of rotation, said walls projecting in a substantially radial direction from an outer circumferential surface of the wheel into an annular chamber defined between the tire and the wheel, and wherein proximal ends of the walls are connected to an annular member which closely surrounds the outer circumferential surface of the wheel, and wherein proximal ends of the walls are connected to an annular member which closely surrounds the outer circumferential surface of the wheel, the proximal ends of the walls are pivoted to the annular member and the walls are biased towards their radial positions.

• at least a pair of walls, said walls having major surfaces and having free ends which project in substantially radial directions from an outer circumferential surface of said wheel into said annular chamber, said major surfaces of said walls extending substantially perpendicularly to a circumferential direction of said wheel.
