This fun and simple practice tire jump will make a wonderful addition to your obstacle course. A special lightweight design makes it very easy to move around, and when not in use, it comes apart in only 4 pieces. The tire is made of 3" thick foam sections that connect to form a hoop with a 24" diameter opening. The tire is attached to the frame by ball bungees, and by sliding it up and down you can adjust it to any height. There is some simple assembly required (no tools needed) and included is free colored tape and instructions for you to decorate the tire. One of our most popular items!
