TRED HD Recovery Board Device is made from a high-quality custom blend engineered Nylon enabling high levels of flex while delivering superior strength and durability. The mix of elasticity and tough rigid design in the main body means that the TRED HD will maintain a high level of pressure on your tire to provide ultimate traction whilst still being able to take the flex from the vehicle’s weight on unstable and uneven ground. TRED HD’s special all season formulation will aid you all year round in ambient temperatures from -15 degree C (5 degree F) to 70 degree C (158 degree F).
