Falken AZENIS RT615K+ Extreme Performance Summer Tire

The Falken AZENIS RT615K+ is an extreme performance summer tire born from Falken's championship-winning motorsports heritage. A direct evolution of the competition-proven RT615K, the RT615K+ builds on a proven foundation with a digitally-engineered, nanotech-formulated 4D Nano Design tread compound that delivers superior dry and wet grip while reducing heat generation for consistent performance across extended driving sessions. DOT-approved and fully street-legal, this tire bridges the gap between closed-course competition and daily road use — making it the enthusiast's choice for performance that transitions seamlessly from the track to the street.

Advanced Technology:

• 4D Nano Design Tread Compound: Falken's digitally-engineered, nanotech-formulated compound delivers superior grip and handles heat cycles more consistently than its predecessor, maintaining performance across extended driving sessions on both street and track.
• Motorsports-Inspired Asymmetric Tread Pattern: The proven asymmetric tread pattern promotes precise steering response, driving stability, and longer-lasting tread life — and allows for free tire rotation, unlike directional designs.
• Massive Sport Side Shoulder Blocks: Large outer shoulder blocks deliver extreme lateral traction through corners, providing motorsports-level cornering grip for aggressive driving maneuvers and sharp turn-in response.
• Solid Center Rib: A solid center rib maintains constant road contact to minimize wheelspin under hard acceleration and improve straight-line stability, putting power to the ground when it matters most.
• High-Tension Carcass Construction: A high-tension casing increases handling response and high-speed stability. Twin high-tensile steel belts are reinforced by a spirally-wrapped nylon Joint-less Cap Ply for even wear and long-term durability.
• Zigzag Grooves and Open Shoulders: Circumferential zigzag grooves and open shoulder voids channel water away from the contact patch, reducing the risk of hydroplaning in wet conditions.

Key Benefits:

• Maximum dry and wet traction optimized for warm-weather performance driving
• 200 UTQG treadwear rating — built for both track and street use with full DOT approval for road-legal daily driving
• Enhanced steering response and immediate turn-in feedback for confident, precise handling
• Asymmetric tread pattern allows free rotation for greater flexibility in maintenance
• Ideal for autocross, HPDE track events, canyon runs, and spirited street driving
• Competition-proven performance derived from Falken's championship-winning motorsports program

Important Cold Weather Notice: The AZENIS RT615K+ is an extreme performance summer tire and is not intended to be driven, stored, or serviced in near- or below-freezing temperatures, through snow, or on ice. The ultra-high-performance compound will harden when temperatures are consistently below 45°F (7°C), which can result in irreversible compound cracking. This tire is designed for warm-weather use only.

Available in a wide range of fitments to suit performance compacts, sports coupes, sports sedans, and muscle cars, the AZENIS RT615K+ delivers the grip, precision, and durability that driving enthusiasts demand — equally at home on a timed autocross course as it is on a weekend canyon run.
