we've had bad problems with treads, even though the traction is amazing, turning creates a whole new set of trouble. the amount of torque required to turn is immense and is related to surface area to ground, so don't have too much traction otherwise the motors will draw too much power and reset constantly. also you will get heat problems, so don't completely encase them, leave an airflow channel and add fans! before you chose your timing belt, experiment as to which one gives the best traction without being to hard to turn, and keep in mind that each tread could have as much as 65 LB pushing down, so weigh them down when testing. also too much tread can leave a metallic ice from Colombia two years ago, where they physically could not move because the motors did not have enough output.
