huh??? footballs and basket *****??? not hardly, do you know how small the frame is on an ATV? There's no-way you can fit a deflated basketball or football in the frame!

 

actually most of them are in the front of the frame(by the motor or in the back by the swingarm.

But I would say get the tallest lightest tires you can find and air them up to about 30psi(will be a harsh ride in rough stuff but you should be able to float, and strip off any unneccesary weight you can.
