Team 48 has used treads 2 out of the last 3 years and we have had allot of success with them. If tensioned properly and if you have a lowered center point to reduce skidding and increase turning they should never fall off and they will rarely break. we have used the same style twice now and it works well, it ts the TK10-K13 pulley style with the self aligning groove,and the TK10-K13 Belt profile to match. we have also used two different backing materials, in 2004 when there were slick plastic topped platforms to climb onto we used a Linatex (Red) backing, in 2006 when it was mostly carpet we used the supergrip (Green or Blue) backing to dig into the carpet.

*Do only if you have the time*
we have also transfered our tread system from 2004 to 2006 in form of a module, for ease of replacement of broken treads.
