1. A track system for a vehicle, the track system comprising:
a drive sprocket including:
a hub connectable to an axle of the vehicle;
a plurality of teeth extending radially outward of the hub, the plurality of teeth including a first tooth;
a rim at least indirectly attached to the hub, the rim including a resiliently deformable tread;
a resiliently deformable track disposed around the drive sprocket and tensionable up to a rated tension exerting pressure against the drive sprocket, the resiliently deformable track having a track-inner surface and a plurality of lugs projecting therefrom;
the track-inner surface including a track-inner-path surface and a track-inner-drive surface, a track-inner-path-surface portion in contact with the resiliently deformable tread;
the plurality of lugs including a first drive lug and a second drive lug, a track-inner-drive-surface portion extending between the first and second drive lugs;
the first tooth located between the first and second drive lugs and spaced away from the track-inner-drive-surface portion
such that when the resiliently deformable track is tensioned to a rated tension, the track-inner-path-surface portion exerts a track-tensioning-path pressure against the resiliently deformable tread, thereby deforming the tread radially inwardly towards the hub; and
the track-inner-drive-surface portion to be displaced towards the first tooth.
