Product Details

The Falken Azenis RT615K+ is a championship-winning ultra-high-performance street and track tire engineered for today's sports cars, performance compacts, and sport sedans. Built on world-spec construction with an advanced compound optimized for both street and circuit use, the RT615K+ delivers consistent, confident grip whether you're commuting or attacking a road course.

A motorsports-inspired 8/32" tread design featuring a solid center rib and massive sport shoulder blocks provides serious traction and cornering response at the limit. With a UTQG rating of 200 A-A and an XL (Extra Load) rating, this 245/40R18 tire is a go-to choice for performance enthusiasts who demand proven track capability without sacrificing everyday street drivability.

Key Features:

  • Massive Sport Side Shoulder Blocks — deliver motorsports-level grip and unsurpassed cornering response for maximum lateral stability
  • Solid Center Rib — significantly reduces wheel spin by lowering contact patch void ratio under heavy acceleration
  • Race-Inspired Tread Compound — proprietary formulation provides excellent traction across a wide range of track and street conditions
  • High Tension Carcass Construction — increases handling response and high-speed stability for confident performance at the limit
  • XL (Extra Load) Rating — rated at 97W, supporting higher load capacity for heavier performance vehicles
  • UTQG 200 A-A Rating — reflects the tire's performance-focused compound with excellent traction grades
  • Available in 21 Sizes — ranging from 14-inch to 18-inch rim diameters to fit a wide variety of sport and performance applications

The Falken Azenis RT615K+ (MPN: 28533881) is the preferred track tire for autocross competitors, time attack drivers, and street performance enthusiasts who refuse to compromise on grip or response.

Good price but when buying a car's outside mirror you need to see which side the mirror is for (Driver's/Passenger's)
