This technology was developed initially for winter products that require heavy blading for maximum traction, but suffered from poor lateral stability due to the low block stiffness. When the car corners this applies larges lateral forces on the tread block elements.

With traditional blades the block is allowed to deform as the block elements slide one against the others.

With the bubble blades, the half spheres interlock as pressure is put on the block and the spheres presses one against the others which reduces the movements and stiffens the block providing increased lateral stability. The block can therefore deform circumferentially providing traction, but retains it’s lateral rigidity for improve cornering
