Customer Review:
The new directional tread patterns improve dry grip by increasing the Land/Sea ratio and pattern stability in the shoulder, whilst wet traction is improved by increasing the groove area in the crown.
Improved tyre life is provided by aligning the pattern direction at the front to resist braking and steering forces, whilst the rear pattern is aligned to resist acceleration and cornering forces. Aligning the patterns in this orientation not only reduces stepped wear; it also allows the use of softer compounds to further enhance grip. Improved handling with progressive, positive steering characteristics is achieved by using new inflated tyre profiles. The new profiles are based on a single radius concept, which minimises changes to the contact patch areas and steering geometry, as lean angle increases.
The new Sportmax D208 tread compounds are derived from our racing programme, yielding high levels of grip, both wet and dry, with a short warm up period. The new compounds use Solution Styrene Butadiene Rubber (SSBR) polymers reinforced with a new type of "Ultra Fine Grain" carbon black to enhance grip and extend tyre life. The rear compound is further reinforced with silica.
The progressive, positive, steering response of the front tyre is aided by the use of a radial casing overlaid by two angled cut Aramid tread reinforcing breaker belts. These belts have high lateral stiffness to resist deformation of the tyre profile and contact patch during braking and steering.
The superb high speed stability of the rear tyre is provided by the use of a radial ply casing overlaid by a Dunlop "JLB" single Aramid tread reinforcing breaker belt. This construction improves the stability of the contact patch and reduces internal stresses in the tyre by resisting tyre "fling" at high speed.
