SLICK: External profile and internal structure to maximize the dimensions of the contact area, in all the driving phases. Belt geometries and materials to optimize the lateral force transmission generated during cornering. Tread specifications with different compound to perfectly adapt to every combination of track surface and temperature.
RAIN: External profile and softer constructions that increase the footprint to find grip even on slippery, wet track. Exclusive pattern to maximize the water removal from under the tread, both in longitudinal and lateral direction, reducing the aquaplane risk.
Main usage: Praga/Radical SR3 & SR8
