Weight, Traction, and torque. That's what you need. The weight needs to be directly over the axles and you need traction to pull. If you are going to do this on pavement, then you need more surface area of rubber on the pavement, i.e. slicks. If you are doing this on the dirt, then you need an aggressive tire like a Super Swamper Bogger or something with a chevron pattern. In both cases, air-down your tires to make the contact patches larger. You'll rip the frame out from underneath that 'yota.
