The Blacklion BU66 225/55 ZR17 101W XL Run Flat is an ultra high performance radial tyre designed for powerful saloons, sports touring and sports coupes. The pattern of its asymmetrical band offers many advantages. The interior area is designed to evacuate water, which gives better grip on wet roads. The exterior area has larger contact areas, which offers traction on dry roads. The silica-based compound reduces heating, improves adhesion, braking and reduces rolling resistance. The spiral steel heel band increases the structural stiffness of the tyre, providing a smooth ride.
