The ADVAN Neova AD08 R (R for new Revolution in street tire tread compounding) is Yokohama’s Extreme Performance Summer tire developed to excite sports car, sports coupe and performance sedan enthusiasts who have a passion for fast and fun driving. ADVAN Neova AD08 R is designed to increase grip and improve handling on dry and wet roads. However, like all Extreme Performance Summer tires, these tires are not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
Yokohama ADVAN Neova AD08 RADVAN Neova AD08 R tire’s tread compound features more carbon to increase dry grip and Micro Silica to enhance wet grip. A Macromolecule polymer blend increases tread rigidity and resistance to wear, while Yokohama’s Orange Oil Technology maximizes performance and minimizes environmental impact by replacing some of the petroleum oil traditionally used in tires with oil harvested from orange peels. The new compound develops better initial dry grip and control, while increasing wet performance and resistance to wear. 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 resist hydroplaning and 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. The sidewalls are reinforced with steel cord inserts to resist lateral deflection and enhance control and cornering stability.
At the end of 2016, Yokohama changed the Uniform Tire Quality Grade (UTQG) of their ADVAN Neova AD08R Extreme Performance Summer tire to reflect a 200 Treadwear rating.
UTQG ratings for Treadwear, Traction and Temperature are based on tests conducted by tire manufacturers and reported to the National Highway Traffic Safety Administration (NHTSA). These regulations allow tire manufacturers to under-rate their tires’ capabilities, but prohibit over-rating them. UTQG ratings are required to be printed on their labels and branded on tire sidewalls.
Yokohama assigned the 180 Treadwear rating when the ADVAN Neova AD08R was introduced, however subsequent Yokohama wear data revealed the tire line earned a 200 Treadwear rating.
With some competition rules now requiring higher UTQG Treadwear ratings, Yokohama decided it was time to officially change the ADVAN Neova AD08R line’s rating to accurately reflect its capabilities.
*In order to help drivers confirm which tire they will receive, we have identified the tires by listing their Treadwear rating on the product Specs tab.
Like the motorsports tires this Extreme Performance Summer street tire has evolved from, the ADVAN Neova AD08 R 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 AD08 R tires must be serviced, stored and driven at temperatures above -10 degrees Celsius (14 degrees Fahrenheit) to maintain its performance and avoid tire damage.
