The Royalblack Royal Explorer is an ultra high performance (UHP) summer tire for passenger cars, offering a sophisticated profile suited to sporty driving styles. The profile is, of course, asymmetrical for better responsiveness and perfect reliability under all conditions. The contact patch is wide. On the outside, the shoulders are reinforced for better tire protection and improved cornering stability. The four wide longitudinal grooves connected to the wide lateral sipes ensure drainage for equally effective grip on wet roads.
