A lot of people will recommend the use of blue nitrile roughtop tread since it is supposedly the longest lasting and has great traction on carpet. It is more durable than the orange natural rubber tread sold by Andymark. Although between the two, I am not sure if there a substantial different in traction.

Every team has different experiences with tread - understandably though, due to different wheel sizes, drivetrain fps's, driving time, and handling.
