The Azenis RT615K is Falken Tire's championship-winning Extreme Performance Summer tire developed for driving enthusiasts looking for street-legal, motorsports-type performance. By combining world-class construction with an advanced tread compound, the Azenis RT615K is designed to maintain grip in both street and track conditions. Performance-tuned for dry and damp conditions, the Azenis RT615K, like all Extreme Performance Summer tires, is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.

Azenis RT615K tires use Falken's advanced, high-silica content AZ Compound III molded into a motorsports inspired asymmetric tread design to offer consistent grip at high temperatures along with enhanced traction in damp/wet conditions. Outboard, Azenis RT615K tires feature Massive Sport Side Shoulder Blocks featuring a variable depth design that enhances lateral stability to deliver motorsports level grip and cornering response. A Continuous Center Rib zigzags around the tire' circumference to provide constant rubber-to-road contact that helps reduce wheel spin by maintaining contact during heavy acceleration. Inboard, circumferential grooves and notched tread blocks increase the void ratio to promote wet traction.

The tire's internal structure includes a high-tension casing featuring twin steel belts reinforced by a spirally-wrapped nylon Joint-less Cap Ply to promote even wear and high-speed durability.

The Azenis RT615K+ is a further evolution of Falken Tire's championship-winning Extreme Performance Summer tire, the Azenis RT615K. Developed for drivers of muscle cars, sports cars, street rods and performance sedans who want ultimate grip in warm, dry and wet conditions, the Azenis RT615K+ is not intended to be serviced, stored nor driven in near- or below-freezing temperatures, through snow or on ice.

Utilizing the proven internal construction and motorsports-inspired asymmetric tread pattern as its predecessor, the Azenis RT615K+ features Falken's latest Extreme Summer Performance-targeted compound. The updated compound is designed to further satisfy the increased performance expectations of competitive drivers through additional dry grip. The Massive Sport Side Shoulder Blocks deliver extreme levels of lateral traction through turns, and the solid center rib effectively puts the power to the ground by providing constant contact with the road. Inboard circumferential grooves and notched tread blocks help evacuate water from the contact patch, i mproving wet traction and hydroplaning resistance.

Internal construction of the Azenis RT615K+ includes a high-tension casing to help increase handling response and high-speed stability. Twin, high-tensile steel belts are reinforced by a spirally-wrapped nylon Joint-less Cap Ply to promote even wear and durability.

Extreme Performance Summer 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.

Note: 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.

The Azenis FK510 is Falken's Ultra High Performance Summer tire developed for the drivers of sports cars, sporty coupes, performance sedans and modern muscle cars who want dry and wet traction and handling in a refined package. The Azenis FK510 is designed to deliver driver confidence in warm conditions, so like all Ultra High 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 FK510The Azenis FK510's 4D Nano Design tread compound is molded into an asymmetric, Adaptive Constant Pressure (ACP) pattern design. ACP improves distribution of pressure throughout the contact patch for enhanced directional stability and reduced stopping distances, and the wide, outboard shoulder blocks deliver the lateral grip required during performance driving. The tread compound was designed at the molecular level to optimize adhesion in wet conditions, and the Switchback Siping helps to maximize rubber-to-road contact during wet cornering. Four wide, circumferential grooves allow water to flow through the contact patch to resist hydroplaning.

Internal construction of the Azenis FK510 utilizes Falken's Tension Control Technology casing mold shape to provide a flexible middle sidewall area for reduced impact harshness and a rigid outside shoulder and bead area for handling capability. Its two wide, steel belts are reinforced by a hybrid Aramid and nylon undertread cap ply to provide added rigidity and high-speed stability.
