The Falken AZENIS RT660 is an ultra-high performance tire inspired by intense competitors on racetracks seeking stability and unrivaled traction. Its motorsports-inspired tread compound delivers unmatched grip. The internal construction of the Falken AZENIS RT66 features a new rigid carcass construction that enhances overall stability and steering. Two large deep-side grooves tread blocks evacuate water from the contact patch, making this a street-legal tire. This iteration comes with a directional tread pattern and a solid center rib that improves acceleration and braking power.

The Falken AZENIS RT660 includes extra stiff sidewalls, offering better turn-in and steering response than softer models with a less comfortable ride. These are sensitive to cold weather and have expected durability of 60,000 miles. Due to its high levels of performance and grip, the RT660 earns high praise from driving enthusiasts and amateur competitors. The Falken AZENIS RT660 range from 14 to 19-inches of the rim, making it a perfect competitor in the autocross and track day world.
