1. A tire testing device comprising:
a road surface;
a carriage configured to rotatably hold a test wheel on which a test tire is mounted and capable of traveling along the road surface in a state where the test tire is in contact with the road surface; and
a plurality of guide mechanisms including a first guide mechanism and a second guide mechanism, which are configured to guide movement of the carriage in a traveling direction,
wherein each of the plurality of guide mechanisms includes:
a rail extending in the traveling direction of the carriage, the rail having a first side facing in a first direction and a second side facing in a second direction opposite the first direction; and
a runner fixed to the carriage and capable of travelling on the rail,
wherein the runner includes:
a plurality of rollers capable of rolling on the rail; and
a plurality of bearings configured to rotatably support the rollers,
wherein each bearing is a rolling bearing including rolling elements rolling on a circular track,
wherein the plurality of rollers include:
a first roller capable of rolling on an upper surface of a head of the rail; and
at least one of a second roller capable of rolling on a lower surface of the head of the rail and a third roller capable of rolling on a side surface of the head of the rail,
wherein the rail of the first guide mechanism and the rail of the second guide mechanism are arranged parallel to each other,
wherein, in the first guide mechanism, all of the rollers except for the first roller are disposed only on the first side of the rail of the first guide mechanism, and
wherein, in the second guide mechanism, all of the rollers except for the first roller are disposed only on the second side of the rail of the second guide mechanism.
