215/45/17 Nankang AR1 tire

Product introduction

The Nankang AR1—a road-legal tire in the 215/45/17 size—is a high-performance semi-slick designed for drivers seeking maximum grip on dry roads and during track use. Developed for sports cars, track-day vehicles, and performance-oriented builds, it offers an excellent balance between grip, handling precision, and road-legal usability.

Purpose of the part

Tires provide the direct link between a vehicle and the road. On a Renault Sport or Alpine sports car—or any performance-tuned vehicle—they play a vital role in traction, braking, road-holding, and front-end precision. Thanks to its semi-slick design, the Nankang AR1 optimizes the contact patch with the ground, enhancing both grip and stability during dynamic driving.

• Reduced performance on a racetrack or during spirited driving
• Increased risk of hydroplaning or loss of control if the tread is excessively worn
