The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The ground-engaging side of the track features a tread pattern that is repeated uniformly or not over the entire length of the track. The tread pattern comprises a plurality of projecting traction lugs each having an upper edge. The internal side of the track features a plurality of protuberances called drive lugs which engage in the sprockets. These sprockets are driven by the snowmobile engine and transmit its power to the endless track. The braking power is also transmitted by the sprockets to the track. It is characterized in that the drive lugs have a pitch distance half of the pitch distance of the tread pattern therefore doubling the number of lugs engaged in the sprocket. Such tracks reduce noise and rolling resistance.
