On the road the tyres certainly lived up to the billing, as the D05’s wet grip is remarkable with little loss in traction and braking performance experienced when conditions got wet. This is thanks largely in part to the tyre’s wiper block design, which not only increases the road contact area, but its sharp and angular shape enable it to disperse water easily with its “Edge-Effect” that breaks the water tension and reduces the water-film between tyre and road surface. From there the D05’s four wide longitudinal grooves enables it to channel the water out easily, clearing the way for the tyres to grip the road.
