Dunlop tyre technologies

CARCASS TENSION CONTROL SYSTEM (CTCS)

Carcass Tension Control System (CTCS) controls casing stress distribution, optimising the tension in different areas, resulting in more consistent and controlled line holding, straight-line traction and better feedback.

DYNAMIC FRONT FORMULA (DFF)

The front tyre section shape and mould profile have been optimised using Dunlop’s Dynamic Front Formula (DFF) design approach. This provides the ideal balance between steering effort, stability and feedback, delivering unparalleled rider confidence and enjoyment.

HISILICA

An increased Silica content is used to promote compound flexibility at low temperatures. Used to reduce a compound's reliance on temperature to offer optimum grip in wet and less than ideal conditions, as well as to increase mileage.

MULTI-TREAD (MT) TECHNOLOGY

Years of success in global Superbike, Endurance and GP championships have resulted in the development of a pioneering multi-compound, which is transferred to many of our current Sportmax track and road products. By mixing compounds, the same tyre can display different performance properties at maximum leaning angles than when upright during straight line speed.

JOINTLESS BELT (JLB) CONSTRUCTION

All our radial street tyres are designed using a combination of Computer Aided Design (CAD) technology and Finite Element Analysis (FEA) as well as JointLess Belt (JLB) construction (either front or rear). JLB construction eliminates the belt overlaps resulting in smoother handling and a more stable contact patch with the road.

RAYON PLY CASING (RPC)

Rayon is used as casing ply material, to improve mileage & shorten warm-up time.

HEX SHAPE BLOCKS (HSB)

Through a new block layout technology called Hex Shape Blocks (HSB), which are polygonal blocks with additional edges, more grip is generated in multiple axes, increasing directional control. This allows for more stable handling, especially on very hard terrain and rocky surfaces.

Benefits

OPTIMISED FRONT PROFILE AND REVISED SIDEWALL TRANSITION

Provides light handling and reduced stand-up tendency when braking in curve whilst delivering perfect feedback.

NEW COMPOUND BLEND

All new compound blend which combines wet grip resin in the shoulder compound with silica and ultra-fine carbon black. This provides increased safety margin on wet surfaces and better outright performance within a wider operating range.

DFF-OPTIMISED MOULD PROFILE AND SECTION SHAPE

Using Dunlop's proven DFF (Dynamic Front Formula) the front and rear tyres' section shapes have been intricately optimised and matched to provide responsive handling and confidence-inspiring stability.
