Ultimate high-performance tire delivers extreme precision and maximized grip for high-powered sports cars. The ultra-high performance Vredestein Ultrac Vorti is a result of cooperation between Dutch manufacturers Vredestein and Italian automobile designer Guigiaro. While its sporty-looking asymmetrical tread might be the first thing that catches the eye, it's the tire's performance values that are really important - and they doesn't disappoint. The Ultrac Vorti is among the safest tires on the market, with a full silica tread compound and 4-radii contour that optimize its grip and handling. It features four broad longitudinal grooves for efficient drainage of water, while the flexible region in the middle of the tread guarantees excellent braking performance on wet streets and low rolling resistance.
