The first MTB tires to engineer the Specialized Sweet Spot Ply through casing angle for dramatically increased grip & control. The new Specialized Grid Gravity Radial tires reinvent how trail riders experience grip and compliance. By increasing the angle of orientation to the tested Sweet Spot Ply, these tires achieve groundhugging conformity that amplifies traction and comfort-without compromising the lateral stiffness riders rely on for hard cornering.Unlike pressuretuning, which rapidly kills compliance as PSI rises, or choosing a sub-optimal casing angle for the intended experience, our Radial casing construction creates the Sweet Spot inherently: lower radial stiffness, preserved lateral stability, and a ride quality that makes technical trails feel smoother, faster, and more controlled.
