The ADVAN Neova AD08 is Yokohama's Extreme Performance Summer tire developed for the drivers of sports cars, sports coupes and performance sedans that have a passion for sport driving. The ADVAN Neova AD08 is designed to provide high levels of traction, responsive handling and driving control on dry and wet roads, however it is not intended to be driven in near-freezing temperatures, through snow or on ice. The ADVAN Neova AD08 tread compound combines fine particle, Micro Silica (MS) with Hyper Density Carbon (HDC) to provide adhesion in damp and dry conditions. This compound is molded into a directional tread pattern that features twin circumferential center ribs and extra-wide Uniblock shoulders to increase cornering stability and steering response. Three large circumferential grooves and HydroArc Channels in the shoulders enhance wet traction. The tire's internal structure includes two wide steel belts reinforced by spirally wound nylon to provide strength and high-speed capability while the sidewalls are reinforced with steel cord inserts to resist lateral deflection and enhance control and cornering stability. Like the motorsports tires this Extreme Performance street tire has evolved from, the ADVAN Neova AD08 radial's construction and compounds have been tuned to maximize the tire's traction and performance within a specific range of ambient temperatures. Therefore, unlike less highly-tuned tires, Yokohama's care instructions specify that due to its compound characteristics, ADVAN Neova tires must be used and stored at temperatures above -10 degrees Celsius (14 degrees Fahrenheit) to maintain its performance and avoid tire damage.
