The Falken Azenis RT660 is a high-performance tire that offers maximum braking and acceleration capabilities. 

Falken engineers used a new, softer compound in the design of the Azenis RT660. 

The Azenis RT660 has a directional tread design to switch tires from side to side. This reduces wear, as performance tires typically wear on the inside, and swapping the tire extends the useful life of the tread.

Although there are two large grooves and deep side grooves in the outer tread blocks to shed water, these tires are not recommended for wet weather.
