They look like plastic, won’t they break?

Due to the special material blends and product design they can handle high levels of flex, are highly durable and wear resistant. The mix of elasticity and tough rigid design means that TRED's maintain a high level of pressure on your tire to provide ultimate traction whilst still being able to take the flex of being under vehicle weight on unstable ground. You may notice minor white stress marks when exposed to high levels of flex but this is what the material is designed to do – flex and bounce back time and time again.
