Kumho has recently had new tire concepts, the Smasher and the Sealant. The Smasher uses suction plates to create a vacuum between the tire and the road, making traveling up steep hills easier. The shape of the Smasher tire also allows it to grind and destroy small rocks in the way. The Sealant does not focus on terrain, but rather, convenience. The sealant tires will fix tire penetration by filling the pop with gel, which will slowly fix the tire.
This is related to engineering as the tires require complex designs and building to make.
