"Truck On (Tyke)" is a 1973 single by the British glam rock band T. Rex. Neither the track nor its B-side, "Sitting Here", appeared on an original T. Rex studio album, but both were added as bonus material on re-releases of the 1974 album Zinc Alloy and the Hidden Riders of Tomorrow. The record was poorly received critically and did not perform as well in the charts as previous T. Rex singles. The single was in the UK charts for a total of eleven weeks, peaking at No. 12, Truck On (Tyke) was the last T. Rex single to break the top 20 until 1975's New York City. Marc Bolan acknowledged that "Truck On (Tyke) is my 14th hit record and I wouldn't be at all surprised if it didn't make number one." Later, Marc would claim the move to be deliberate, stating that its release "was a planned thing. I wanted something not so good to happen to compare it (future material) against."
