The Hoosier DR2 is definitely what we recommend for drag racing or any use on the drag strip, but now we have a tire for the street and track as well. This tire has been track tested on cars ranging from 500WHP to 1000WHP, and we have been very impressed with what these have to offer our customers. While this may not be the best tire for launching the car, this tire still puts down the power when going from a dig. This tire really shines during roll racing events and on tracks that require actual manipulation of the steering wheel, or what is scientifically called “turning”.


The Azenis RT660 is Falken’s Extreme Performance Summer tire developed for motorsports enthusiasts, participants in track days, or any driver looking for competition-ready levels of dry traction and handling. The Azenis RT660 is designed to provide maximum performance in warm, dry to damp conditions, and like all Extreme Performance Summer tires, it is not intended to be serviced, stored, nor driven in near-and below-freezing temperatures, through snow or on ice.

Falken Azenis RT660 Callouts

Utilizing a motorsports-inspired tread compound enhances the traction delivered by the Azenis RT660 for acceleration, braking, and handling in dry and wet conditions. The low-void, symmetric pattern maximizes the rubber in contact with the surface. Massive shoulders deliver extreme levels of lateral grip, and the broad, continuous center rib provides solid on-center feel and longitudinal traction for acceleration and braking. Deep, circumferential grooves and full-depth notches help evacuate water from the contact patch to enhance hydroplaning resistance.

The internal construction of the Azenis RT660 features a two-ply, polyester casing utilizing Falken’s Crosshatch Carcass design to enhance handling and stability. Two wide, steel belts support the tread area and are reinforced by two polyamide cap plies to further improve handling and high-speed capability.

Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.


Flexing of the specialized rubber compounds used in Extreme Performance Summer tires during cold-weather use can result in irreversible compound cracking. While compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.
