Abstract
A protrusion that projects from the inner wall surface of a tire house towards the rotational axis side is provided on the tire house side in a range from an edge of a tire cross-sectional width S that corresponds to a vehicle inner side of the pneumatic tire to a vehicle outer side. A plurality of ridges and/or recesses is provided on at least one tire side section on the pneumatic tire side. Where a maximum distance of the ridges from the surface of the tire side section is designated as Hp, a maximum distance of the recesses from the surface of the tire side section is designated as Hd, and the tire cross-sectional width of the pneumatic tire is designated as S, ranges 0.005≦Hp/S≦0.05 and/or 0.001≦Hd/S≦0.01 are satisfied.
Claims15
A vehicle air resistance reduction structure, comprising:
- a tire house of a vehicle;
- and
- a pneumatic tire mounted within the tire house;
- wherein
- in a state in which the pneumatic tire is mounted on the vehicle, and a rotational axis of the pneumatic tire is disposed so that the vehicle can move forward,
- a protrusion projecting from an inner wall surface of the tire house towards a rotational axis side is provided on a tire house side in a range from a tire cross-sectional width edge that corresponds to a vehicle inner side of the pneumatic tire to a vehicle outer side;
- and
- a plurality of ridges and/or recesses is provided on at least one tire side section on the pneumatic tire side, a maximum distance of the ridges from a surface of the tire side section being Hp, a maximum distance of the recesses from the surface of the tire side section being Hd, a tire cross-sectional width of the pneumatic tire being S, and ranges 0.005≦Hp/S≦0.05 and/or 0.001≦Hd/S≦0.01 are satisfied.
