2004 marked the final year Mattel would use the small monster truck wheel design in the Monster Jam line as the transition to the large monster truck wheel design began to take into effect as part of a broader rebranding effort to emphasize a more rugged, oversized look. The transition to these larger wheels was meant to appeal for a more visually striking aesthetic to match the larger-than-life monster trucks seen in real-life events. By making the trucks appear even more extreme and powerful, Mattel sought to enhance the play experience and keep the brand fresh and exciting for its audience.
