Next generation Azenis RT Tire. (The NEW Azenis)
Improved motorsports grade cap compound maintains grip over a wide range of operating temperatures.
Increased internal void ratio delivers enhanced wet grip and aquaplane resistance under competition conditions.
8/32nd molded tread depth reduces ""squirm"" when new while providing predictable mileage for street use.
200AA UTQG qualifies for SCCA Street Tire Class competition.
Note: This tire does not qualify for Falken's 30 day ride guarantee.
A note on RT-615 pricing. You probably have noticed that the RT-615 is priced significantly higher than the older RT-215 (Azenis Sport). We assure you this is not an attempt to gouge our fellow auto enthusiasts. Falken Tire Co. has chosen to set the price point much higher on this new tire. In addition, Falken has imposed a minimum price that internet dealers can sell this tire for. We are currently selling this tire at the lowest price allowed by Falken Tire Co. If you see others selling it lower let us know!
